SYMEF?

So you are talking about an active powered speaker. An active speaker does not require the amps be in the speaker box -- a design choice that puts the amplifiers in an environment that is not beneficial to them.

S/S amps cope perfectly well in the loudspeaker cabinet. Most studio actives have them there and although it is partly for convenience, I don't think they'd do that if there were serious problems with it. I think that's probably an old hi-fi myth put about by the manufacturers of separate amplifiers.
The actives I've heard certainly have fewer problems than most conventionally separated amplifiers/speakers that I've heard. And, as I said, they have most of the benefits of single driver with some advantages over them.

Anything with caps in it (to bring forward the biggest offender) is subject to microphonics. Not that i've yet found a SS amp i could live with for the midtweeter.

On,
Someone would have to bring by one for me to here. With no tubes...

Give your speakers a treat, go SYMEF. There a few constructors in your area, they might bring the SYMEF during the audio fest. Your speakers will come alive
You might even consider offering your speakers plus HAL amplifiers as a kit
FWIW the most musical & transparent fully SS amp I've yet heard is:

and Gary's severely tweaked out Behringer wasn't hurtful either:

mind you that was about 4yrs ago, so things may have advanced since then
or not

Thats very interesting. Did the amplifier employ feedback ? What was the gain ratio ?
Yes on Feedback (lots i understand), for the rest you'd need to talk to the designer, Daniel (aka Duo), he has at least one thread on the subject.
I do know it had a very high bandwidth, it was adapted from a current amp for driving the electron guns in a CRT.

Yep, ditto on that. Super clean, very nice amp. But don't forget, it's a Solid State "Tube Amp".FWIW the most musical & transparent fully SS amp I've yet heard is:

Spent a lot more time with the Fostex. I still can't get what the single driver thing is about. Horrible breakup at 6800, a bottom end that can barely make it to a sub and distortion several times as high as I expected. This thing is far more evil than my crossovers. What am I missing?
It would be interesting to hear Mr. Pass and Mr. Curl comment on that little FET idea.
