This is a point to point hand-wired tube amp with the beauty of simplicity of classic circuit design that comes at $400. The way it comes sound like an old tube amp that is still somewhat enjoyable as the sound has warm tube distortion. I did...until I modified the amp. The most distortion comes from the power tubes biased so cold, like 50% of total power dissipation. Changing the 500 ohm wire-wound cathode resistors with lower ones like 250ohm will clean the sound up and you will be very surprised. It will radically change how the amp sound. Then, changing the factory PSVANE EL34 tubes with quality Tungsol EL-34B or JJ EL34 will drastically improve the sound. Then again when you think it can get any cleaner, changing the factory Shuguang 6n2j tubes with quality ones will again make it sound so much cleaner. I rewired the 6n2j socket for 12ax7 in order to use quality 12ax7 tubes. If you know how to solder and such, both replacing cathode resistor and rewiring the socket aren't very hard thing to do. Reisong A12 comes with 12ax7 sockets but with hefty extra cost of $100.I have both A10 and A50 MKIII, and I prefer how A10 sounds. Oh, I would recommend having a decent set of speakers with quality tweeters. That makes huge differences. I enjoy this amp through Definitive technology BP9060 speakers with 90dB effeciency.In short, this amp is a great value, and with swapping bias resistors and replacing all the tubes (and rewiring for 12ax7 because it's much easier to find quality 12ax7 tubes) with quality ones it becomes an amazing value.

I’ve read/seen lots of raving reviews about this tube amp so decide give it a go. Honestly for the price I didn’t expect any miracles. But I was blown away by the sound as soon as I played music on this amp. I come from a solid state amp which costs 7 times of the price Reisong. While this Reisong doesn’t beat that amp in the details department and bass clarity, it exceeded my expectations in overall presentation.Just enough highs to bring out the clarity, warm rich palpable mids and detailed bass.And the build quality is way above its price class. Beautifully and solidly built.The packaging was the best I’ve seen in anything I’ve ordered online, ever. It looked like it could survive a 20 foot fall.I bought this for my secondary listening room but tested it with my 92dB efficient Elipson Heritage XLS 15 speakers in 4 Ohm tap and it sounds amazing. When connected to 8 Ohm tap, the bass was bit too much and lacked details. 4 Ohm tap solved those issues. I only listen at moderate volume levels.I highly recommend this amp. I will definitely buying one of their their higher end amps in near future.

I'm an audiophile, but I'm sure there are others who are more knowledgeable than me here. Having said that, in my system, this was the perfect fit and certainly lives up to the hype.Also, it was my first time dabbling with Chinese hi-fi gear, and I must say, the quality really did surprise me, and I feel like I came at it with a negative bias too. If you look at the equipment coming out of China on an objective level, it's hard for any other country to compete on price-performance.MY SYSTEM- Klipsch RP-8000F's- Topping D10s DAC- Reisong Boyuurange A10 Tube Amp (this amp)- Blue Jean Speaker and Interconnect CablesPACKAGINGThere was some mention of poor packaging for what must have been an open-box purchase. The packaging on the brand new unit that I got was impeccable. It could have survived the nonsense abuse that Air Canada and Fedex subjects our parcels to with ease. You'd best believe that, if they packaged my firstborn premature child this way, I'd feel like the baby would survive a fall or two.Also, regarding what must have been an open-box purchase, my unit did not have any fingerprints or marks. It was literally perfect!See pics for the packaging I got. I'm telling you it doesn't get any better than this! Look at the corner holders. It literally prevents the inner box from even opening up.SOUND QUALITYI warmed up the tubes for 20-30 minutes before playing and sampled with a few albums of various genres. My favorites include opera, jazz, vocals, and lots of Beatles. The vocals were crisp, clear, and tubey in all of the right ways. I don't know the precise audiophile jargon to describe what's in my mind, but what I mean is that, the sound is very engaging, rich, and "life-like" in the way you would want a tube amp to sound. If you were looking for a 1000% transparent sound, you generally wouldn't be using a tube amp in the first place.With that said, it's not like the sound was sickeningly warmed-up. It felt just right- like the singer was in the room with you, or rather, you were in the studio or concert hall with the singer.PRICE AND VALUEYou simply can't get a better tube amp of this quality at anywhere near the price, from everything I've researched. (It's currently Jan 3, 2021, and I bought it before the holidays in 2020). Buying it off Amazon cost only a bit more than shipping it yourself, paying the hassle of taxes and duties with customs, etc. so unless your have way too much time on your hands, just get it here.Compared to a non-tube, solid state amp, this was the better choice for our use case that consists of a of music and vocals. However pairing this with a warm-sounding DAC might not be the best option, in case the warmth is additive and stacks, but like most audio gear, you have really have to try it to know for sure - you might just notice that it maxes out at a point instead of stacking.COMPATIBILITY WITH SPEAKERSThis will really depend on how loud you play your music, and the sensitivity of your speakers. My Klipsch RP-8000F's are very high sensitivity, and I never need to this amp set beyond 50%. The DAC is also set at only 75% when attached to my windows PC.YMMV, but keep that in mind. People who say this thing doesn't output sound simply aren't pairing their speakers and components properly, in my opinion. Wattage isn't the only thing that matters with amps. This is well established. With good, sensitive speakers, you're not going to be playing beyond 5 - 6 W in the majority of situations. Also, having said that, it's clearly stated what the wattage is for this amp. Don't blame the amp because you're not reading and building your system properly.CONCLUSIONI'm very pleasantly surprised by the hi-fi equipment makers from China, starting with Reisong Boyuurange. I had always been a made-in-USA sort of guy, for a variety of reasons. I still am, technically, as you can see in my choice of speakers. However, I really can't argue with the quality (build and packaging), value, and overall sound of this tube amp.If you're on the fence about this tube amp, which is relatively cheap by audiophile standards, Amazon has great return policies that could help you test the waters. This thing was a no brainer for me! Would do it again!

Shipping 5/5Amp was ordered in April with the knowledge that delivery would be between June 2 - 5 and arrived on June 5.Opening the outer box revealed another cardboard box, so double packed in heavy cardboard boxes.The amp was suspended in packing foam with the tubes well packed in foam and boxes placed inside the protective cage. Nothing was able to shake or rattle and arrived in perfect condition.Appearance 5/5As other reviews state this amp is heavy and has a solid feel to it. The mirrored finish is spotless and the amp looks great with protective cage on or off. This really is a beautiful piece and the "cool" factor is off the charts when those tubes are glowing. Even with the protective cage installed you can clearly see them.Setup 5/5Amp came with wiring schematic and English instructions but really not needed, pretty self evident where the tubes go and there is a notch to align them properly. Pop in the tubes, connect your speaker wires and interconnects, plug it in and fire it up. If it takes more than 5 minutes to get this up and running, its you, not the amp.Functionality 5/5Again very simplistic, On / Off and volume control knobs on the front. Very nice feel to the action of the knobs.Around back you get two RCA inputs, CD and AUX with a button to switch between the two inputs. Also binding posts with options for 4 or 8 ohm speakers. No problem with inserting on RCA interconnects or the banana plugs on the speaker wires and the connections seem tight.One review here complained of no way to switch between inputs and had to buy a switch box - not required, there is a little black button at the back you use to select. It is not obvious but it is there. Maybe they could have put another knob on the front to select, but this is a minor issue as due to clearance required around the amp for heat accessing it is no problem.I have my CD player directly into the CD input and Zone 2 from my receiver feeds the AUX so I can listen via bluetooth or my CD collection stored on my NAS.Sound 5/5With this being my first tube amp, and due to my age I wasn't alive for the first go around of tube equipment I wasn't sure what to expect. Once the amp was hooked up I turned the power on with the volume turned all the way down. I originally hooked it up to an old pair of satellite speakers just in case as I was not risking my Klipsch RP600M.After letting it warm up for a few minutes to make sure it was all good I hit play on the CD player and gradually turned up the volume to about 12 o'clock and I have to admit was very pleasantly surprised with the volume and sound quality right away. Tubes apparently require a burn in period until they sound their best but sounded very good to me. With everything appearing to be in order I shut down the amp and connected it to my Klipsch and fired it up. I was blown away by the volume and quality of sound, I find it hard to believe it can get any better than this. This is a great sounding amp right out of the box.Vocals and instruments are fantastic: piano, guitar, cymbals reveal incredible detail. I can't comment too much on the bass response, it is pretty good and punchy but you can't expect too much with only 12W and 6 1/2" woofers. My AUX feed from my receiver goes through a Rolls Tiny Stereo 2 Way Crossover to feed a subwoofer that adds to the bottom end turning this into a great full range system. With efficient, larger speakers this would probably not be required so I can't deduct anything for that.I have maybe 15 hours on it and no problems so far and have run the volume to around 2-3 o'clock.One reviewer commented on the power, this is quite loud when paired with efficient speakers, I have yet to be wanting for more and was extremely pleased as 12W does not seem like a lot when used to 100W+ amps. If it is not loud, it is your speakers or a problem with the amp.Overall 5/5When ordered I thought this might be more of a novelty, display piece for me and was fine with that. Within one day of use I knew that was not the case, this will be my go to for music listening for quite a while. Sometime in the future I may experiment with different tubes, but really no need to do so as they sound really good.If you are thinking about it, just buy it, you won't be disappointed.

This is my second tube amplifier from China. I have previously purchased a Yaqin MC-13S about 5 years ago and it's still going strong. This unit arrived triple boxed, the outer amazon box was labeled fragile and after years of ordering and selling online I have found that labeling something fragile is a magnet for abuse, and this was no exception. the outer box was in very bad shape. Fortunately the amp itself comes double boxed and protected with foam. The tubes come in 5 boxes securely wrapped underneath the safety cage.The amp itself seems well constructed and the polished finish is beautiful. Something to note and something I learn with the MC-13S is that it needs to be gently cleaned regularly or it will attract a lot of dust, scratches and stain very easily and it's a pain to clean. I have made a nice nylon cover for it to keep it from happening again.Setting it up is very straight forward, set the tubes in the proper socket and orientation ,plug your speakers, your source and the power cable, turn it on and let it warm up for a bit and you're set. The amp will automatically adjust the bias so no need to do anything. The sound out of this little amp is excellent, very warm and clean provided you have the proper speakers for it. It is most definitely not a 12 Watt per channel amp as advertised (maybe 6 watt) and it will struggle to drive anything under 90db efficiency. My amp is powering a pair of Klipsch Heresy that are very sensitive ( 96db) and can get to be quite shrill and shouty with solid state amps, but with this amp there's none of that.Now to the bad part. In my first inspection I found that the power switch is not mounted straight, so the knob sits bent very slightly to the right, it also came loose so I had to re tighten the screw that holds it in place. Next was the power cable, it does not make proper contact when plugged in to the amp socket and had to be replaced. The cable is just a standard IEC power cable so none of this was a big deal and was an easy fix but you shouldn't be expected to be fixing things like this on a new amp even at the low price. Finally, one of the EL-34 tubes was defective, this would really be an issue if you don't have any spare El-34, KT-77 or 6CA7 tubes around. Now the good part is I contacted the seller TubeAmplifierStore and they replied very promptly with all the info I needed about compatible rectifier and preamp tubes. They also sent me the schematic of the amp and a new tube, it arrived two days later.Overall I think is a great entry point to tube amps if you are curious about tubes and the kind of sound they bring to music or if your budget is below more know tube amp brands that can be quite expensive. Just make sure you have some efficient speakers or you're not really gonna get much out of this amp.UPDATE: It's been 18 months since I got it and It's still as good as back then, no issues at all. I bought socket adapters to replace the 6N2 preamp tubes with 12AX7, worked great but they're not connected the same so don't try it without socket adapters. Also bought an RCA switch, having 4 sources and only two inputs gets annoying fast. Lastly the price has gone up since I got mine, It's still great for what you get but not at the bargain price it once was.

Just kidding. No not really. If this thing sounded just "okay" I'd still keep it for looks alone. Although, I do want to give it plenty of hours first before I pass judgement. I will return with a sound update, just wanted to drop some sweet pics! Although, right off the bat I've noticed how much more bass I'm getting out of this than from my Onkyo 9150.Couple of points aside from the sound:- You do not understand how heavy this is. I shudder thinking about the A50.- The packaging is superb! Kept everything safe and sound (pun intended).- Better binding posts than most speakers I've had. Quite surprised at this!- Using my 90db BR03 and A5.4 with dial mostly at 9 o'clock. Plenty loud.- Absolutely stunningly beautiful in person. Pictures don't do it justice.- Ordered an assortment of tubes for some good ol' tube rolling. I will return.*UPDATE: Been using this for about a month now and have tried it with Chane A5.4, Focal 706, Triangle BR02, BR03, and Klipsch RP600m. Best pairing so far has been the RP600m, followed at a distance is the A5.4. I'm not a fan of what it did to the BR02 or BR03 as it made the BR03 too bright and the bass too bloated on the BR02. I'm currently using it with Gold Lion KT77 and Voskhod 6N2P.It definitely has more personality and soul than my 9150, which is quite surprising as the 9150 is a long-standing favorite of mine for its tone. The A10 is also more textured and sounds more spacious. The music sounds more "alive". The only downside is it can sound a bit bright and bassy with certain parings. It really transformed the bass on the BR03 and made it way too bass heavy for my liking, so much so I had to pull it out another foot from the wall just to take the edge off. The BR02 pairing was just bad, but that speaker already sounded like an inferior BR03 to begin with. But it really makes the RP600m sing, especially with the two sets of Gold Lions I'm running them with (KT77s and 12AX7s w/ socket adapters). The bass is incredible. Tight, controlled and with a shocking amount of heft with absolutely NO bloat! It'll be fun to try this amp it with other speakers!*UPDATE 2: I've built my tube collection a bit. I have 4 sets of power tubes: stock Psvane EL34b, Electro Harmonix 6CA7, Gold Lion KT77, and Tungsol EL34b. 3 sets of preamp tubes: stock, Voskhod 6N2P and Gold Lion 12AX7. And 2 rectifiers: stock and Gold Lion 5AR4. I'm pretty much happy with all except the 5AR4 which makes gives it a thinner overall sound and the Psvane EL34b which sound kinda lifeless. Gold Lions definitely are the best for me, but the 6CA7s are also right up there and look nicer due to their fat-bottles and are a better value. I've had no issues with the preamp socket adapters and have probably 150 hours on them with the Gold Lion 12AX7s. Although, I've noticed there is now a Reisong A12, which has the 12AX7 sockets as standard instead of the 6N2P.F.Y.I, my pictures are 6-30 second exposures at f/1.4 - f/5.6. The tubes are nowhere near that glowy during use.

Please keep in mind this review is from someone that has never used a tube amplifier before. I have been through tons of solid state amps and receivers since the 80's. Love to listen to music and blast a good home theater system and have separate systems for both. In the late 90's through early 2000's I taped a TON of live music using quality mics and gear so I know my way around audio components and what sounds good. I have always loved vinyl and love to play with gear so I decided to give a tube amp a drive and and see what the difference was.I didn't want to spend a ton, but I also didn't want crap. Did a little bit of research and came upon this little bundle of joy. Seems Boyuurange had a few of the US versions in stock in Amazons PA warehouse (I am in Upstate NY) showing next day delivery, so that made the decision easy as I hate waiting :).First off the packing and shipping of the product is super pro. No way this thing will take any damage during shipping with the way they had it packed. Came with updated English instructions that address a lot of the questions they are seeing on Amazon which shows they care about customer service. They also send you a nice welcome email after purchase with some good information in it.This little beast is heavy as hell. My wife about dropped it during the handoff with the UPS guy as she was not prepared for the weight. She was like, what the hell is this? Seriously, you could anchor a small boat with this amp.The build quality of this amp is top shelf IMO. The stainless steel case combined with the super heavy duty transformers is where all the weight comes from. Has two knobs, one for power one for volume. Nice heavy duty knobs, and the power knob makes a very satisfying click when you switch it on. All the speaker and rca ports in the back are solid as hell also.5 tubes come nicely packaged with it that are super easy to install. As another reviewer noted, one of the boxes contain two tubes so don't freak when you see 5 holes and 4 boxes. I had the amp set up and plugged in quickly.Keep in mind this is a integrated amplifier with a pre-amp stage that you can't bypass. Doesn't mean you can't run this with a different pre-amp, just requires a little more playing around with the gain/volume on both pieces of hardware. I know many purists will poopoo this kind of set up since you are going through 2 pre-amp stages, but I have played with enough audio gear in the field (pre-amps, amps, DA converters, etc.) to say, let your ears decide what sounds best.Since I have multiple audio play back devices (CD, DAT, Solid State Recorder, Vinyl, etc.) I needed to keep using my current receiver and hooked up the tube amp via the pre-amp outputs on the receiver to power the speakers. I am using a Pioneer Elite 2 channel network stereo receiver in conjunction with the Reisong tube-amp. Played around a bit, but found setting the Reisong volume to around 12 o'clock while adjusting the Pioneer to the desired listening volume yielded good results. Still have room to crank it up, but no need to. I am using Klipsch R51-M speakers for listening with this amp as high sensitivity speakers are a must for an amp like this. I have a powered sub-woofer I use with my vinyl and cd's, but have to turn off for my live recordings, or risk blowing out the sub :) Damn low bass response from Schoeps Microphones.Out of the box this amp sounds amazing and I can't wait to see how it will only improve with time. The soundstage is remarkably wide, natural and airy. I am hearing things I have never heard in my vinyl and recordings before. The attack and decay of instruments is amazing with crystal clear highs, clean mid's and tight, accurate bass. The tubes really do give a nice warmth to the music with out being overpowering or too colored. While my vinyl has never sounded better, this amp has breathed new life into my live music recording collection. Have about 800 hours of live music I recorded onto DAT 15-20 years ago. Gov't Mule, Phish, Dead etc. all sound amazing through this amp. The detail of the recordings really shines through and the soundstage created makes me feel like I am at the live show again. Going through and listening to all my favorite shows and it's like hearing them again for the first time.I will report back after I get more break in time on the amp, but so far this little tank of an amp has completely transformed my music collection. Can't wait to listen to more music! Pictures includedUPDATE 5/17/20Reporting back after really breaking this amp in with 100's of hours of music (Vinyl, CD, DAT). My opinion on this amp just keeps getting more positive.The first thing I want to address is some of the reviews that say this thing can't be turn up loud or you get distortion, pops, crackles, etc. I am not sure what equipment others are using, but something has to be wrong if you are having those issues, possibly the amp is not working properly? I played with many different ways to run this since I am running it into the pre-amp inputs on my Pioneer network receiver. I started out with the volume on the amp turned to the 12 o-clock position and then adjusted volume to the desired position on the Pioneer. Sounded good, but I like to tinker so I decided to apply the same logic I used when taping shows to my stereo set up. The less signal attenuation in your chain of equipment as you go from your MICS to recording media, the better the sound. So I cranked the amp all the way to max and then adjusted the volume on the pioneer. WOW, cranking the tube amp up all the way completely changed the sound. Cleaner, clearer, more airy, more detailed, just flat out better across the board. I can't turn the receiver up more than 50% now or it will make my ears bleed. Not distorted, just too loud! This is why I question some of the issues others are having with this amp to either user error, or a bad piece of equipment in your set up. With a pair of high sensitive speakers and a proper set up you should have no issue cranking this thing.This amp is the best purchase I have made for my listening enjoyment, EVER. The performance you get vs. the cost is pretty amazing. Combine that with incredible build quality and you just can't go wrong.Great amp, as I go through my music collection its like listening to these albums for the first time!UPDATE 1-14-21This is hands down the best purchase I have ever made for my listening pleasure. I listen to a lot of music while I work from home and this little amp gets a ton of use. Usually the first thing I turn on to warm up as I make coffee before tuning into my favorite morning radio talk show. Key point, always let this baby warm up before using, it will just treat you better.I love the way it even makes the radio talk show sound, like I am in the studio with them. There is such an airy realness to the soundstage this magic box produces that is hard to explain while blending in this beautiful tubetastic warmth that is never overwhelming, just...perfect...I listen to so much more music now because of this amp. A good vinyl pressing sounds so amazing with this amp so getting old classics I love but never had on vinyl has been a real treat. I can also vouch that it’s built to last. Had a bad power surge in my house that killed my internet modem, CD player and power strip the amp was plugged into and made a horrible sound....I thought for sure it was fried....nope, came back on and is fine...Just get it, you won’t be disappointed. The satisfying click it makes when I turn it on still makes me smile every morning, and that’s just turning it on....Update 4/12/22- Turned the amp on today, hard a pop in the speaker and now the right channel us completely dead in the amp. Tired switching cables, reseating tubes, etc, channel is completely dead. So bummed, I loved this amp, sent a note hoping this is something that can be fixed, was hoping to get more than 2 years out of this amp.....
