Wow! Just unwrapped this and played with it for an hour plus. This amp has more beans than a pair of the Fosi V3 monoblocks it will be replacing. This really makes my Klipsch towers come alive with the Wiim Ultra feeding it. Perfect visual matching BTW. Great clarity at low volumes. Plenty of REAL power at loud volumes. Never got hot, just comfortably warm, as expected. It sounds great! Well balanced and able to be very dynamic. Surprisingly heavy (plenty of heatsinks inside). Oozes quality from the packaging to the plug connections. I’ll update this later with comments about the internal DAC (same as the Wiim Ultra IIRC). So good, I’m buying another for my other Wiim Ultra. Just wish they had made an option for silver too.

I was delighted to see that WiiM rolled out an upgraded power amp that connects nicely with the ultra streamer. I received the item today and was impressed with the packaging which reminded me of Apple’s branding. I connected the Vibelink to my pair of floor-standing Prestige 75F speakers and was impressed with its breath. Even the low notes punched hard with tons of headroom. I’d love to see WiiM come out with mono blocks down the road.

The WiiM Vibelink Amp completes the welcome WiiM offering of an amplifier and control hub /preamplifier pair that WiiM initiated in 2024 with the introduction of the WiiM Ultra control hub/preamplifier. The usual WiiM Amp features and functions, with the exception of the RCA analog and the digital optical and coaxial inputs and the digital to analog converter (DAC), are absent from the WiiM Vibeamp. The WiiM Ultra control hub/preamplifier supplies all of the usual inputs, outputs and other WiiM capabilities found in the other WiiM streaming amplifiers (WiiM Amp/WiiM Amp Pro) and more. The Vibelink Amp does not include a remote control or streaming functions as these are present in the WiiM Ultra. On the front of the Vibelink Amp is an analog volume control and a selector button that cycles through the RCA (analog) and Optical and Coaxial (digital) inputs. There is a standby/factory reset button on the rear of the Vibelink Amp. The Vibeamp Amp can be powered on via a 12V trigger from another component such as a WiiM Pro/Pro Plus music streamer or from the WiiM Ultra. However no 12V trigger cable is supplied with these components. (I used the 3.5mm auxiliary connector cable that is included with the WiiM Mini (Mini sold separately) to supply the trigger signal and it worked to supply the 12V trigger signal from the Ultra to the Vibelink Amp). The WiiM Vibelink Amp can receive firmware updates over Bluetooth (BT) from your phone. You can also turn the Vibelink Amp on and enter standby mode using the WiiM Home app and your phone.The WiiM Vibelink Amp's additional power and dynamic headroom (Rated at: 100 Watts per channel at 8 ohms and 200 Watts per channel at 4 ohms) versus the 60 WPC @ 8 ohms/120WPC@ 4 ohms for the WiiM Amp and WiiM Amp Pro streaming amplifiers was welcome and very evident in use.Note that the WiiM Vibelink Amp Owner's Manual specifications page states that the rated 100 WPC @ 8 ohms / 200 WPC @ 4 ohms only applies when using the Optical or Coaxial digital inputs. When using the RCA analog inputs the rated output power of the WiiM Vibelink Amp is the same as for the WiiM Amp and WiiM Amp Pro (60WPC@8/120WPC@4.)You must use banana plugs to connect the speaker wires/cables to the WiiM Vibelink Amp. WiiM supplies (4) metal gold colored (plated?) banana plugs that accept bare wire with the Vibelink Amp. I chose instead to use the Sewell deadbolt gold plated banana plugs (available from Amazon.)I use the WiiM Ultra's USB output option to connect to the USB-C input of an SMSL PO100 PRO digital to digital converter (also sold on Amazon). The SMSL PO100 PRO automatically re-clocks the digital stream sent from the WiiM Ultra. In my listening, the re-clocked digital stream improves the sound of transients, instrument separation and placement. If you own a WiiM Ultra and use the Ultra's digital output to connect to another component (DAC or amplifier) you won't be disappointed by adding the SMSL PO100 PRO in the digital stream. (The improved audio is especially evident when listening with headphones.)The WiiM Vibelink Amp product description is spot on when stating the WiiM Vibelink Amp "delivers superior clarity, deep bass, and dynamic range for an immersive listening experience". I heard layered instruments and vocals where the WiiM Amp had none.In summary, the WiiM Vibelink Amp pairs perfectly with the WiiM Ultra. The WiiM Vibelink Amp sounds great and the added power and dynamic headroom really helps if you have a large room or lower than average efficiency speakers.WiiM should include a 12V trigger cable with the WiiM Vibelink Amp. In my system the WiiM Vibelink Amp ran 88 - 94F. This is slightly warmer than the WiiM Ultra's 86-88F.Using the optical SPDIF connection, I compared the WiiM Vibelink Amp with the WiiM Amp and the WiiM Amp Pro. Via optical the sensitivity of the WiiM Vibelink Amp is higher by ~3dB. I did not test the RCA pure analog inputs.The additional power/headroom is very evident. Using the WiiM Vibelink Amp, WiiM Ultra and the optical connection I drove a pair of "ELAC 4" passive wired bookshelf speakers", (model BS41), available exclusively from Amazon), until I had to turn down the volume. I never got the WiiM Ultra's volume control above 60/100. Note that the ELAC BS41 is a  6 ohm speaker with lower than average efficiency (~82dB), rated for 40 Watts nominal / 80 Watts peak power.Unlike both the WiiM Amp and WiiM Amp Pro, the WiiM Vibelink Amp has no subwoofer output. The WiiM Ultra features a single RCA connector for subwoofer output with bass management.

Used this for an outdoor setup driving a pair of Polk Atrium 8's. It's a long 75ft run from the receiver to the speakers and my old Denon wasn't quite up to the task. I noticed an immediate improvement as soon as I hooked up this amp to the speakers! Setup was super easy and I'm very happy with the sound quality.

I don't know. I was so looking forward to getting this amp. The write ups made it sound like it would be stunning. I was drawn to it because of its simplicity. I"m running an old school stereo set up. Turntable. Phono pre amp. Passive speakers. Amplifier. I am very much into listening and buying vinyl. I have been since the '60s. That being said, I have been really impressed with my current set up of Klipsch Reference R-50M speakers through an AIYIMA 19 PR0. I up graded the tubes to GE5654W and it sounds remarkable with the EQ set flat. It has a very deep and well structured sound stage. Actually pretty amazing for a price under $200 even with the tube upgrade. I am space limited, so when I saw WiiM was coming out with the Vibelink, audiophile quality, I thought that if my system sounds so good now, just think how much better it could even sound with the vibelink. Well, I guess the Vibelink does what it is supposed to do, but it doesn't sound very musical to me. There is good clarity and separation, but to me it sound flat and lifeless. It certainly doesn't have the depth and bring out the best of my speakers or records. To me it lacks musicality. But, maybe that is what it is designed for...very flat response. Anyway, I'm going to hang on to it, but I have re-hooked up my AIYIMA and am very happy with how it sounds with my turntable and speakers. And I have answered a question that was on my mind. The grass is not always greener on the other side. I want to add that probably my biggest disappointment with this amp is the lack of low end drive. It just really lacks any low end oomph and doesn't pack any punch. It sounds like it needs a bass EQ boost to me. ADDENDUM: I hooked the Vibelink up to my system again to give it another try for a day. Sorry to say it was still disappointing. The bass response is very anemic. I want to be sure to say that I don't think there is anything wrong with this amp, it just doesn't sound as good, to me, as my current set-up. I decided to return it.

I was waiting for this product with a lot of excitement as I own an Ultra and thought they would make the perfect match. Well, with the optical cable worked for an hour or two, it stopped working after that !!The RCA cables still work and connect to the Ultra but with a huge sound difference vs the optical. Was not happy with that at all!I’m hoping the defect is because the product is pretty new and they will be fixing the bugs.I havent lost my trust in WiiM but this experience was a frustration.

It gets super hot
