Bryston owners ONLY

I posed a similar question a few weeks ago only it was whether to buy and bridge a second 3B-ST or buy a 4B-ST or two 7B-STs. The concensus was that the speakers' load was the issue since Bryston did not rate the bridged 3B-ST at 4 ohms. My speakers would present a 4 ohm load. The pair of 3B-ST amps would probably handle the load, but run hot. If the bridged 4B-STs can handle your speakers' impedance then you have a good option buy buying a second amp. That said, I'm hoping to get 7B-STs. You might write Bryston...

So what is the purpose of the upgrade? I can't imagine you needing more power to drive the Sonatina II's, they are fairly sensitive at 93db. Do you prefer the sound of the 7B-ST or 14B-ST? The 7B-ST operates in high-current or high-voltage mode (series or parallel, I forget which is which). High-current mode isn't recommended for speakers over 3 ohms. The high-voltage mode is essentially the same as bridging a 4B-ST. I had the 7B-ST in my system for a one week audition. The biggest enhancement over the 4B-ST is stereo separation. There was an increase in dynamics in high-current mode and a slight sweetness in the treble but you couldn't use it with your speakers.

If you have money to spend and want to improve your system I would consider power conditioning, power cords for your source, IC's, or speaker cables.

Hi. I am new to this site and this is my first post here though I have occasionally inhabited a neighbouring low brow mid fi site.
I have just traded in an 11 month old 4BST & BP 25 for a similar vintage 14 BST.There was nothing wrong with the 4bst, its superb value for money,but I was never entirely happy with the BP 25.In my view it was too clinical and neutral and did't gel with the metal dome tweeter of the B&W CDM 9NTs.Hence out went the 4bst & bp25 to be replaced by the 14bst and an ancient ARC LS2B(on temporary loan from the dealer).This combination is heavenly.The tubes on the preamp add just a hint of sweetness to the brute strength of the 14bst. This is a match made in heaven.I wonder what Patrica Barber & Diana Krall will sound like when I add a new preamp.Its a toss up between the ARC SP 16 or the CJ PV 14 L.There are much better preamps out there but beyond my budget.
Basically the 14 bst is a brilliant power amp and the equivalent Krells/MLs cost two to three times as much with no dramatic or tangible improvement in any area.The 14bst ( the SST has only cosmetic changes) is the most musical of all brystons.
Cheers.

Thank you all for your opinions, Jazzdude is absolutely
right. I love the 4B-ST, why change? I think this hobby,
as much as I love music at this level, sometimes brings
out questionable behavior in us all i.e. maybe tuning out
the people we love too often, spending vast sums of money
with questionable results. I think I'm going to take my
wife to dinner, maybe listen to her abit more.
Thanks

Sunnyboy--I agree with you about the ARC LS2 with Brystons. I'm using an LS2 MK2R, into 7B-STs. Wish I had the version, like yours, with balanced inputs, however. So far I haven't found one with remote as well.
