Thanks for the info, quite interesting. The amp is pretty special, I've had quite a few amps over the past few years and this is a keeper.
I've got my drivers in TC's bigger is better boxes. (tall folded pipes) Not ideal, as they are built for a smaller driver, but they work. And with the new amp, they actually sound good in these boxes. My goal is to put the Fostex's in a sealed cab (or O.B.) with a larger woofer for the lower end of things, crossed around 200hz or so. I also have some supertweeters I may try for a little extra air on top.
As for the rest of the system, Audio Note CD 2.1x, Thorens TD160 with SME and Shure cart, Grado phono pre, FT Audio LW1 passive buffered pre. IC's are primarily 47 labs OTA with Eichmann Bullet Plugs, (best IC's I've heard, including some pricey players). I also have two Yamaha servo'd 8" subs. I have some power bits, which help, hoping to mod the pre at some point and rewire the tone arm.
This is far from perfect, but is sounding better with the recent changes. New speaks and some room treatment of some sort and I may have something.
Cheers!
