CLASS A AMPLIFIERS

Atmasphere, thanks for your informative comments. But I'm not clear on why it is unacceptable for some speakers to have an amp that increases power into a lower impedance load. My Martin Logans are superb, but among their very few weaknesses is the fact that they roll off the topmost treble...and the impedance in the treble is 1 ohm or less. Surely an amp that can deliver more power into this tough load has the potential to provide better treble performance...?

Atmasphere, thank you for your explanation. Although I'm no EE I think I understand what you're getting at. I will have to try a suitably high quality and high power SS amp on my panels to see what it does to the treble.

Yada, currently I am using the Odysseys; their midrange is simply excellent, and they have good dynamics, but (as mentioned) they are not the equal of my previous ribbon speakers in the topmost treble. (Overall a much more musical experience; it's the midrange that counts the most!)
