Top!
Excellent quality product with top sound. Using it to drive my centre speaker in my suround sound set-up. Only wish would be to be able to switch off the power light which is possible in the stereo version of this amp. As ususal, quick & efficent dispatch from Audiophonics.

Superb
I bought a pair of these to replace my existing monoblocks. The RCA/XLR switches allowed me to remove a passive pre-amp (and lots of cables). I am delighted by the difference. My speakers love the power on tap and my ears love the sound, with deep, punchy bass, even at low volumes and very clear mids and treble. They took a day or so to burn-in.

Sadly, it took more than two months to receive them after they were shipped thanks to post-BREXIT customs delays on both sides of the la Manche, but I cannot blame that on the product or Audiophonics.
