I started with one 4B-ST, driving Sound Lab A-3s. Bought an additional 4B-ST for bridging. Read/spoke with several experts about pros and cons of bridging and decided to replace them with 7B-STs, with which I'm very happy. Still wonder if by doing so I in effect simply replaced bridged 4B-STs with "other" bridged 4B-STs (in the form of 7B-STs). The 7B-STs do offer a bit more versatility with the mode switching (series/parallel) feature however.
I haven't heard the 14B-SST, but from what I've read it's a better amp, with even lower distortion. With my present arrangement using monos, I have very short speaker cables, so going to a single amp would require some changes in that respect.
I think if I make any changes in amps it will be to tubed units, such as the ASL Hurricane monos. Hate to think about paying full retail though. With all of the swapping with Brystons, I've managed to upgrade without losing any money in the various transactions, and the 7B-STs were new units at a used price.
