I've purchased three of these now, one for myself and then two as gifts. They look great with the glow from the tubes and the meter, giving a warm ambiance. The small footprint is easy to accommodate. The remote is easy to use. Bluetooth works well with good range. Hook up was easy and straight forward. I'm using Bluetooth, RCA, and optical. The sound is quite nice, with good power and detail.I listen to this everyday and I'm very happy with it.

Little beauty! Very solidly built. Wonderful controls. Very warm sound. I have this amp paired with a pair of vintage BBC Rogers LS3/5a’s and a Cambridge Minx 300 sub. It’s a great combination with the amp having just enough power to push the system to fill a room. Highly recommend.

I purchased this amp along with some Fluance speakers so I could have a very carefully controlled test bed for other components, speakers, etc. So far, pleasantly surprised at how punchy and strong this little amp is. I can quickly hook things up to this amp and run tests. I measured all the outputs with my diagnostic equipment and it tested out to the specifications listed for this amp. A very simple, powerful, punchy amp at a good price. Nice.

Sounds sweet and bright with my Deli speakers after upgrading the vacuum tubes, great quality in this price range.

Had the Douk ST-01 for a couple weeks. It arrived with a set of 6AG5 tubes. I paired the amp with a set of Fluance SX6 speakers. Sound is crisp and full. Great bass and treble. Device feels sturdy and well built with nice feeling adjustment knobs. Remote works. I only used the optical input and Bluetooth connection so far. Both worked perfect. Beautiful little amp and looks fantastic with the copper tone accents.

Great quality for a small tube amp. The tube upgraded to JAN 5725W. It sounds better than the tubes that come with it.

I wanted to purchase this a few years ago but couldn't decide what speakers. I found a pair of Realistic Minimus 7 for $20 on Facebook Market Plus in mint condition. After about an hour of playing, I was blown away and the sound warmed up. Looking for a wonderful amp for near listing field.I would recommend this amazing little amp

Good little amp. Great sound. I wish it had a sub out connection.

It is amazing what a nice sound this little thing can provide. Especially I like warmth of the sound (kind of softness) produced by tubes. Pair it with Polk's speakers (like I did) and you would just "bath" in music all day long.

Sound from this amp is 7 out of 10 where my 10 is audiolab 6000a. First thing I did is I upgraded tubes to GE ones. They become warmer but not sure if better. I guess it's personal preference thing. All in all they worth the price but I had to return as my speakers require at least 70 watts to sound their best and this amp barely makes 55 wpc, while advertising 100 wpc. Upon research I found out you can upgrade power supply to get more watts out of it but this upgrade moves this amp to another price leauge where you'll find better options
