I have no idea what Crem1 is talking about anymore (never been a member of a union?), but taking the totality of his comments into account -- including his repeated references to the Audio Critic, where they don't even believe in listening to amps for sound quality -- sorry but I just can't place a lot of stock in his recommendations. I do however take something from Cwlondon's less than positive experience with the reliability and power of the Sonic Impact. Bottom line is I guess we're still waiting for someone to come out with a decently-built, usefully powerful, compact, lightweight and portable (maybe even battery-powerable), class-"D" design control amplifier at a relatively modest price (with or without a DAC built in). I'm hopeful it will happen sooner or later.
