SIT-1 monos (when they can be found) are much more expensive than than the SIT-3s. Occasionally you will find a SIT-2 for sale, usually cheaper than a 3. The SIT-2 is stereo and provides that immediacy of a tube SET amp. The Bakoon 13R integrated ($5K used) sounds good with Nenuphars, although I prefer going FirstWatt.

For a preamp, the Pass Lab ones make for a great combo. On the tube side I have used LTA and Backert, with Backert being my preferred choice. Easy tube rolling if you enjoy that.

It would be interesting to try the sit3 in a dual mono configuration for a more fair comparison to the sit1. All you need is a second chassis, power supply, and then you just move one channel over. Anyone over on the pass labs forum of diyaudio could do it. As I've mentioned earlier in the thread, 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.
Thanks @riaa and @rwpollock Looks like you guys are lucked out getting a pair of SIT-1. All the SITs are unobtonium these days. I will keep my eyes and ears wide open in the used market but if anybody is willing to offload any of the SITs, pm me please :-)
btw, I currently have a PS Audio BHK Pre - can anybody tell if it’s a good match with the SITs ?

@david_ten thanks for the confirmation. You happen to also use a Townsend podium - did it make a bigger difference then just using the Eden spikes on the bare floor ?
