I would recommed the "filter choke upgrade" for both 14B-SST or 7B-SST. Check out the link I sent earlier and search the Bryston Circle (all info is there). Some people on A'Gon sell the amps with the upgrade already done. It made a noticeable difference on the high frequecies for me.
Last year I put my upgraded 7B-SST's for sale here in A'Gon but I pulled the ad and decided to keep the amps. I was considering upgrading to the newer SST2 series. Instead, I just bought a Torus power unit for the amps. The newer 7B-SST2 amps have the Torus stuff built in.
