David,

The T+A’s reasonable DF level and its negligible NFB no doubt contribute to its perception/reputation of being a very organic sounding  transistor amplifier compared to many other solid state brands. Also explains why it pairs so well with your Nenuphars. I guess it comes down to what someone desires as some amplifiers are touted for their DF greater than 1000!!! This is viewed as a + attribute.

Just as luck would have it.. there was a SIT-2 on sale, so I snatched it up. Now I can compare between 4 ohm output impedance with 0.5 damping factor and >100 damping factor.

khragon,
 Nice ! It will be quite interesting to read how these very different amplifiers  sound paired with your Nenuphars. I believe this will be a very enjoyable endeavor.

Wise choice!
I am thrilled with the synergy the SIT-3 has with the Nenuphars and the SIT-2 should be even better from what Srajan heard with the SIT-1.
I think you'll be shocked at the difference between the SIT-2 and your other amps.
You're in for a treat.
