No such thing as "perfect" amp

Mosfets have, even at this late date, too high a gate capacitance to really work well. There is also no such thing as a complementary Mosfet output stage. The p channel device only can act as a constant current sourse for the n channel device above it. So the n channel device is really taking most of the audio load. There is also this famous Mosfet "mist" that everyone with Golden ears hears. A high freq frizzy that surrounds everything like a fog. Until someone is brave enough to bring out the water cooled heatsinks or even stoop to consider a transformers coupled Class A amp then I'm afraid Bipolar transistors operative in complementary emitter followers Class AB is the best of all evils. There is no perfect amplifier. They are all euphonic in their own way. Go listen or borrow amps to hook up with your speakers in your listening space. Most reputable dealers will allow this. Only then can you arrive at what you want. Anyone else recommending an amp is like recommending someone for you to marry. The best! James
