Incredible amplifier!
The amplifier arrived incredibly fast and was very well packaged. It’s aesthetically pleasing and feels like it’s built with high-quality materials. The sound is fantastic, handling the low frequencies with great efficiency! The soundstage is excellent, and the overall tone is smooth, non-fatiguing, and never harsh. I’ve listened to a lot of equipment in my life, and this amplifier is truly one of the best I’ve heard. It’s powering a pair of difficult-to-drive speakers at 87dB with ease. I’m extremely satisfied!

This amp exceeded my expectations. It is not too bright in my system as I was afraid for the d class. For the preamplifier I have atoll pr300 signature. It is neutral with excellent and controlled bass and with a huge reserve of power, the workmanship is impeccable, quality connectors... and as always safely packed by audiphoniccs

Sweet Spot of Class D Power Amplification
I bought this power amplifier to run a pair of difficult to drive but well loved Infinity Kappa 9's. It handles them with aplomb. Zero background noise, a common complaint on prior Class D amplifiers. For 700 Euros shipped, it is a bargain if you don't want to build yourself. The Purifi based amplifiers may put up slightly better specifications, but in my room I can't ask for more than this amplifier deliveres for the price.
