One very interesting thing to me is that forums and reviewers tend to say that his amplifiers sound like the better parts of tubes and solid state combined....he says that is NOT his goal....that his goal is to drive distortion and S/N to a low level and then to tune his amplifiers to sound like nothing...don't add or subtract anything to the sound...not that this is unique because other well regarded amplifier designers say similar things.
I recently purchased the company's new 2Cherry amplifier. Let me be clear, I'm not saying this is the best amplifier in the world as there are a lot of great amplifiers. What I am saying is that this amplifier was transformative to my system https://systems.audiogon.com/systems/7699
What stands out most about the 2Cherry is the incredible level of transparency/clarity that seems to lift a fog that you didn’t know was there which brings the music alive. There is no sibilance, no brightness, no harshness, no artificially pumped up midrange and top end. This amplifier brings you into a detailed, layered, powerful yet delicate soundstage with emotional involvement similar to a live performance.
