To this point I'm not getting much on how the Panasonic unit works. From the PS Audio site there is a descrition of how their digital amp works, summarized chain;CD Data (Pulse Code Modulation) -> D/A conversion -> Pre-amp analog amplification-> HCA-2 (Pulse Width Modulation -> Transistors) -> Speaker outputs
My guess about the Panasonic unit;
CD Data (Pulse Code Modulation) -> Convert to Pulse Width Modulation -> Modify Pulse width for volume ->Transistors -> Speaker outputs
If this is true, it would seem very beneficial.However this is similar to how the Tact amplifier works, which I have heard on huge Tact ribbon speakers. I was not that impressed, as no sonic nirvana emerged.
