"I bought my SIT-1 Mono's (Demo's) for about $500 more than what the SIT-3 goes for new."

That sounds like a great deal. Didn't they sell for $11K when new?
"I found independent power supplies for each channel to be a very substantial upgrade when I did it for my first watt f4s. I think I've said this before too, but it's a really beautiful amp that doesn't get the attention it serves, btw."

I remember reading the 6moons review of the F-4 years ago and thinking they would be perfect if one had a preamp that they loved.

Preamps are sometimes under-appreciated, with more time being focused on amps and speakers. It may have been Robert Harley who wrote that the amplifier determines the character of a system while the preamplifier determines the quality.
