Hey guys (Fedreams, Teajay and Jeffreyb) many thanks for your posts and perspectives!
Teajay......first of all, NL-10 amps, VERY NICE!!! (I'm jealous!) I was looking at one of the other Sig 1's on Audiogon and hate to talk with Neli or Mike unless I wanted to buy their unit (you know the gig, I don't want to use their expertise to buy someone else's component). But if I do want to pay a 'little more' I'll give them a buzz.
Guys.....with all your thoughts, I thought I had made my decision on the Sig One. The only thing that is putting a little damper on it, is that having just received my new amps (Krell FBP 250M monoblocks) I just talked to Krell and they STRONGLY reccomend a balanced preamp for the output to the their amps (mind you, they weren't pushing their preamp), but only that the Full Balanced Power 250M's truly perform their best with a completely balanced preamp.
So, I'm now considering the Roland Synergy. We'll see which wins my 'internal battle'!
