Bryston 7BST 600 Watt Monoblock Review

Totally unrelated to sound quality, but I have always been bothered by Bryston’s cartoonish logo. :facepalm:
I've never owned any Bryston gear but I never thought their logo to be cartoonish.
On the other hand, I like G.A.S. and SUMO gear (I never owned any of it, either).
I guess that you could consider their labels "cartoonish".

One of the better known SAE designers, James Bongiorno, left SAE and founded Great American Sound (GAS)

These 7B's were one of the beasts of the day. Amazing you can get the same power now in a little box that weighs seven lbs.

I have no interest in something that I have to add weight to in order to keep the cables from flipping it over or pulling it onto the floor.
Kind of like putting quarters on the phono cartridge head shell to keep it tracking the record.
No mass: No thanks!

I am pretty sure the 7B will stay were you put it. If you feel like that is still too light there is a Boulder amp that weighs 350 lbs.

Not so bad for a 1993 amp )
Chech here for other measurements

Not bad for 2025 either.
You do realize that the one-hour, 1/3-power preconditioning JA does corresponds to about 250W/4 Ohm for a hour, don't you?
 
I have more amps that I could ever use. Adcom, Pass, and several class d amps. I use my Bryston 14bsst to power my salon 2’s. 26 years old and still my favorite. Serviced once by factory. Hopefully it will still rock for many years to come cause I don’t want to have pick it up anytime soon. Thanks for the review.
 
ASR Superego: measurements alone, price irrelevant, noise is evil, no audiophile tomfoolery.

ASR Id: drooling and fawning over 500 pounds of 30-year-old hyper-brawny buzzing high-end Big Iron not-a-toy amps like those girly Class D thingees, and quite reasonably priced if you stop and think about it

:p
 
Overpriced is very subjective compared to today’s offerings. But they last for a long long time. So the cost per year is low-ish
Very valid point.

I also heard that Bryston often will service their amps after 20 years for free.
 
Some misinformation here about the history.

Stuart Taylor redesigned the Bryston amplifier line which is called the ST series. The ST amps are different than older, not rehashed. The schematics are different. They perform and measure differently, the older amp about 4x higher distortion than the ST, although still awesome. Stereophile has a good interview I linked in my previous Bryston review. Of course, a rehash of the 1978 design is quite a compliment, and actually reason to buy older models with confidence.

Stereophile did measure the SST they are roughly equivalent to the ST series, with a few incremental improvements here and there. All of these various generations have performance that exceeds most any high power amp offered today.

Used isn't for everybody... But for those who are shopping for used gear, to exclude the older Bryston models from consideration one would have to ignore this review with some remarkable measurements from a 36 year old pair of amps, from a manufacturer with legendary reliability reputation, with a matching after-sales reputation for ongoing support of their gear.
