Review: Great little amp! - OK - I modded it a little by adding the copper rings around the vacuum tubes. Buy this is a great little amp. Drives my Eltax Monitor III speakers well and interfaces with Alexa over BT and my 4K UHD TV via Optical connection. Obviously no surround sound. But really good sound. Good looking too and for the small home it’s nice and compact! No problems so far! Will see how I get on. Very basic RC but is does I/O, Mute, Function switching and vol control well enough. Overall I am impressed! Nice solidly made too!
Review: Really quite incredible! - Really a little wonder of an amp here! after having owned it now for a few weeks Ive tried it out on a few sets of speakers at different wattages and ohmage from expensive Dynaudio speakers, some JVC speakers and some cheap 90s sony 3-way speakers and the amp performs amazingly with all of them and scales really well to the size, spec and class of speaker you are using. whether you are using audiophile speakers or cheap hifi speakers this amp is bound to sound amazing especially being able to dial in the woofer and tweeters with the treble and bass controls. The amp sounded MUCH better with the addition of new valves I installed some Mullards and the difference was night and day I would strongly recommend changing the stock valves immediately and getting some good oxygen free copper cabling both will drastically improve the quality. The amps sound is very open with nice overtones from the valves, the transient detail is really not bad at this price point and the tone controls are actually both smooth and not to hyped the treble or bass didn't sound artificial and on a natural flat sounding speaker like my Dynaudios I was able to boost and cut quite a lot without 'hyping' the sound which shows the quality of the EQ curve in the units bass and treble control. Now I knocked off 1 star for a few minor niggles: The left and right output on my unit were backwards/mislabelled left was actually right and the left was right I only noticed due to panning in one of my reference tracks being the wrong way round, a minor QC issue. The VU meter requires VERY loud levels to start dancing about. Headphone output at least on my cans was not very loud and the stock valves as to be expected were brittle and a little shrill. Overall, though fantastic sound quality and lots of bang for buck and a real fun bit of kit that has so much connectivity and function and can certainly kick out the volume! Highly recommend if you have never had a valve hifi before!

### ⭐⭐⭐⭐⭐ Brilliant chip amp
*by T***S on 4 January 2022*

I have a few chip amps . I've built some from cheap boards and bought a couple by smsl I have a douk valve preamp. Their stuff is well made and durable This of note is £20 cheaper on Amazon than their eBay store at present. Looks wise, the combination of underlit tubes and orange backlit vu meter plus aluminium edged black dials looks very classy. It's tiny and mighty Sound , be it Bluetooth streaming Amazon music or Spotify sounds superb. Direct RCA in from my MP3 player also. You can switch using the remote or pressing the volume button I paired it with a set of "Roxel" bookshelf speakers. To be honest I had s set of wharfedales going spare but my wife wanted cherry wood look and these not only look great but sound good also. All in all for a bedroom amp or office amp ( our use) this is superb.
