Bryston 7bsst vs 28bsst?

Jim Tanner of Bryston has stated that the 28B run full power into 4 ohms will trip the circuit breakers in your home panel and they would have problems with Underwriters Labs if this figure were published. Going by the ratings of other Bryston amps usually the 4 ohm rating is about 1.7 times the 8 ohm rating.
Why the obsession about the ratings even if it did not put anymore into 4 than 8 when do you need more than a kilowatt per channel anyway

I can't run my 28s with my pre past 9:00(I could but she'd
rock the neighbourhood+mine).
A couple of thousand watts,you could fill up a 300-500 seat bar and with plenty of sound to spare.
Now if I ever get a bigger house,WE ARE MORE THAN READY.
I was ready with the 4s+7s let alone these superb 28s.

Shannere, the obsession with ratings is that if you have 4 ohm speakers, you could run them with a 500 watt amp that doubles down into 4 ohms without worrying about circuit breaker problems. The whole point is moot if you're running 8 ohm speakers. If you've got 4 ohm speakers, someone had better answer some questions and document it. I have a set of Infinity Kappa 9's that dip to 1 ohm and below. I'd certainly like to know if the amp has the testicular fortitude to handle those low impedances for sustained periods without bypassing the circuit breaker on the rear of the amp or worrying about tripping the house circuit breaker. I'm sure someone that owns a set of low impedance amp-killing Apogees would certainly question this amp's performance at 4 ohms and below. Krell lists its amp at 900 wpc @ 8 ohms and 1800 wpc rms @ 4 ohms.

Sorry, but when putting out that kind of scratch, I'd like to see its 4 ohm performance in writing.

The 7B SST states that it will go to 900 wpc @ 4 ohms. Something tells me that the 28B SST won't perform any better at 4 ohms. So, if you've got a 4 ohm speaker, you could probably save yourself some dough and go with the 7B and be assured of your 4 ohm performance. I still see question marks all over the place for the 28B.

I have no issues driving my MBL 101E speakers which are 4 ohm and dip lower with the 28's which I already answered above.

None of us are manufactures of the amp so I would suggest you contact Bryston, they will provide you with the appropriate information.

I see you use Pass 600's, I actually owned X600.5,s and when hooked up to my MBL's the volume on my Audio Research Ref3 pre was usually at 45-50 and now paired up with my 28's 30-35. Big difference, if I put it up too say 45-50 well that's really rocking the house.

One note of difference in these 28 amps which I have not experienced with any others is that the 1st watt of these amps sounds the same as the last watt which to me is pretty special so you will find your self listening at lower levels and really enjoying.

My suggestion is to contact Bryston and then get a demo pair from a dealer to listen to in your own set-up.
