Bryston 4BSST or 6BST or 7BST

Vvrinc, thanks for your comments. I find that interesting that you prefer the sound of the 7BST to the newer 7BSST. That is one reason I would steer away from the 7BST and get the 4BSST - because I would assume that the SST would sound better. Are the differences between the STs and the SSTs that pronounced that it is worth the extra money. I am still undecided which amp(s) to buy as there does not appear to be a clear winner except that nobody has really said much about the 6B.

I compared the 4BST and the 4BSST and ended up purchasing the 4BSST because of the refinement in the top end. It simply sounded more natural to me

I personally preferred the SST series over the ST. Like others here I prefer the added smoothness and refinement and found them more neutral and less bright. But there are people who preferred the "hotter" balance of the ST series and found them to be more dynamic and involving.

I think the best thing to do is to compare an ST amp with their subsequent SST replacement. But of the amps you mentioned, there's no question to me that the 7BST will be the best amp. First of all, you won't find too many people who actually think the SST series to be a quantum leap in advancement. And second of all, the 7B will be much more dynamic and throw a much deeper and wider soundstage than both the 4B and the 6B regardless of whether it's ST or SST. The 7B is simply a better amp.

I would definitely agree with everybody who has posted that the SST series is better than the ST series. I have owned all 3 versions of the Bryston 3B - 3B, 3BST and 3BSST. Each one is incrementally better than the previous version but none is a huge improvment over the previous one.

Ultimately, I am looking for the best sound. I think the decision is fairly clear for me - the 7BST is the better choice over the 4BSST or the 6BSST.

Thanks to all who replied and helped me out here.

Cheers.
