## Customer Reviews

### ⭐⭐⭐⭐⭐ Outstanding amp.
*by F***D on 5 March 2016*

Having owned a Sonic Impact amp many years ago, I know how good a class D amp can sound. Reading the Topping TP21 spec revealed a T2021 chip surrounded by the kind of audio grade components you don't expect to find in a £58 amp. On paper it looked like it should blow the Sonic Impact out the water and reading a review at [...]further reinforced that view. Unboxing the amp was the first surprise. The casework would be considered good at a much higher price. The face plate is thick brushed aluminium with legends milled into the surface. Not screen printed, but milled! You might expect that on a £500+ amp but not £58. Even the volume knob is solid aluminium with a milled edge and a small depression cut into the surface to indicate its position on the volume scale. The rest of the case is a black extruded aluminium box. Still good at this price point. At the back are quality gold plated sockets and a decent power switch. By now I was expecting this amp to perform as well as it looks. Well, after a 48 hour burn-in, it just did that. Strangely, it doesn't seem to have much character that I can pin down. And that's a very good thing in hi-fi. You don't want components in your hifi adding anything to the music. This amp sounds good out of the box and it sounded even better when I changed the supplied PSU for a Russ Andrews Power Pak II. These are no longer available but cost over £100 when they were. You may think spending twice the price of the amp on a power supply is a little out of proportion. All I can say is you can't get this quality out of any £150 amp I am know of. If you are looking for new amp to drive sensitive speakers, or just headphones, I highly recommend the TP21.

### ⭐⭐⭐⭐⭐ Small and mighty! Superb bit of kit!
*by M***J on 30 January 2015*

I bought this to replace a 35 year old Technics SUV150 amp that had lost a channel! This unit measures about a fifth of the size of that old amp, yet produces as much power (if not slightly more) with less THD, better S/N ratio, and clearer harmonics across the frequency range. Don't be put off by the lack of tone controls, D/A convertors, and input selectors. If you are connecting it to a computer soundcard, these will provide all of those capabilities. My soundcard is a SoundBlaster Audigy RX, and the clarity and quality of the sound it produces, is admirably demonstrated by this amp and the Gale monitors I have hooked up to it. I am very pleased!

### ⭐⭐⭐⭐ Powerful little beast
*by M***N on 8 August 2015*

Seeing as it's near impossible to find a reasonably priced full sized amplifier anymore, seeing this gave me some hope, though I was a little worried as to how such a small device would work.Glad I took the plunge. It powers my bathroom's ceiling mounted speakers well. My only regret is getting a version of this amp that doesn't give full control over treble, bass, etc. The sound it produces can be a little flat.
