Thank you guys, I appreciate the input. Leg pulling is fun as long as you get around to the subject, rather sooner than later. As I am rebuilding my speakers it will be a while before I get to hear this amp perform.

Hey, what are you saying?

I'm building what will be my last amplifier, and it is one with FET output transistors, the ones designed for audio. Design is Indian, and super symmetrical, with current feedback.

I listen mostly to classical music (well Baroque, mostly), where 'pure' is king. That is why I chose a design using Lateral MOSFET's. Two amplifier boards per stereo channel, feeding two mid range units per channel (one with a real ribbon tweeter).

The two most important things in an amp are the power supply, followed the circuits. In stereo, you should have more than enough clean power for almost any reasonable pair of speakers. I'd try to stick to 8 ohm speakers, but it isn't mandatory. Other than that, have fun with it.

As I said in post #3, I like the MOSFET sound, if it's done well. I've been using a 1981 Soundcraftsmen A2502 MOSFET amp in my main system for at least 15 years, and it's the only component that hasn't changed at least twice.

My Perreaux PMF2150B Mosfet amp has been with me since mid 1980, and has since been reworked with premium parts. It compares very well against the best of my other 6 amps.

The Sirius (GamuT) D-200 is a stupendous amp. Now way out of my price range, I wish I had bought one when it first came out!
