I was running a pair of Hawks with an Audio Research VS110. Life was good, but I was still craving something more. Enter the Bel Canto ref1000, and the Hawks jumped to life.
After discussing my situation with Vince from Totem, I upgraded the speakers to Mani-2 Signatures. Wow, another massive jump. I tried the VS110 with them for a few minutes before realizing that it was not a good match at all.
After a year with the Bel Cantos I had an opportunity to buy a pair of barely used Nagra PMA monoblocks and I jumped on it. They were better in nearly every way than the ref1000, but it was only a matter of degree and not the huge overall shift that I had from the tube VS110 to the ref1000.
Funnily enough, the person I bought the ref1000 from was also using Mani-2 Signatures and he upgraded to the top-end Pass monoblocks.
The Mani-2's can take a lot of amplifier and still keep giving back. From my experience, I think the 14b SST would make you very very happy. If you want to save money, the 4b SST also looks like it would work well.
