It is very, very quiet compared to the SS amps in the band. I was assuming that they did not suffer from Nyquest noise like SS amps do. However, we have a Alan and Heath sound board, and those are the best sounding boards I have ever heard. Extremely quiet pre's and warm sounding. So, I guess it is possible with SS.

The difference between shoddy and good can be infinite; any difference between tube and solid state pales in comparison. Take a smart, dedicated audio circuit designer who _believes_ in solid state electronics, give him a big budget and set him loose. Do the same thing with a similarly smart and dedicated audio circuit designer who _believes_ in tube electronics, give him the same budget, and set him loose. When they're done, the differences will be minor, and hugely different (in both price and sound) from something you buy for $100 from Guitar Center. -- Tim Wescott Control system and signal processing consulting www.wescottdesign.com

I remember when I was young and those super low noise RF FETs came out. Everyone (who had the dough to buy those) jumped on them, only to find out that the old nuvistor preamp was in about the same ballpark noisewise but had a dynamic range from here to the Klondike while them thar newfangled trainsistahs didn't. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.
