Bryston 28bsst2 worthy upgrade from a krell fpb70?

My only concern with the Bryston is if it's able to drive a load lower than 4 Ohms. Otherwise, it puts out great sound. However, in that price range, and even cheaper, there are other excellent amps that deserve an audition.

Hi Lecram, At this point, I have put $4,000.00 recently into the inside of my 700cx, very well worth every penny too, and I am going to ride off into the sunset with this amp, it's all new, with modded capacitors and tweaked power supply, I might put the SR reds fuses inside, another $400.00, I am conterplating If there is a need?, also if you put a single pole 30 amp breker on this amp, play for 17 to 20 hrs for burn-in, you will be amused at how much better a 700cx sounds and runs extremly cooler doing this, when you do this 30 amp breaker, have a furutech GTX-D Rhodium outlet on it, these wpo's take 500 to 700 hrs to break-in, however, after 165 hrs, you will enjoy the sound, the wpo opens up a bit to enjoy, and the the furutech GTX-D R does not warm up or get hot with this much current like most wpo's do,best $5.00 that the breaker cost that I ever spent in audio, I would have paid $300.00 for what $5.00 did, it's a win!

Is there a question of reliability, get it fixed if it breaks down! I mean really, come on guys, listen to the amps.... Is it a better fit for your speakers? Is it a better match for system? How does it sound at your preferred listening levels? If your trying to break your eardrums, either amp can probably help you do that, if your trying to get perferred results with your given equipment at your listening preference, then do what any smart buyer would do.... Bring it home and listen for a couple weeks and put back your Krells and hear what you think!

Hi Lecram,

One thing to consider in making your decision, of course, is impedance matching between your Jadis preamp and the Bryston 28B-SST2. From what I can gather, the JPS2 has an output impedance of 1.5K ohms. The 28B has an input impedance of 15K single-ended or 15.5K balanced. Typical rule of thumb says 10X at a minimum is needed on the amp-side, and many people prefer 20X or more to prevent distortion and dynamic compression. So, that puts the 28B right at the edge of compatible with your preamp, perhaps too close for comfort. It might sound just fine but you really should try before you buy. Just thought I'd point out this possible issue, since no one has mentioned it in the thread.

All that being said, the 28B is an excellent amp. I've been using a pair with a VAC Phi Beta preamp (output impedance of 200 ohms) for a few years and really enjoy them. For comparison, I also have a VAC 300.1a tube amp and a Reference Line Silver Signature, which is a boutique pure class A, solid state amp from the late 1990s. The 28Bs more than hold their own against these others, to the point where I've been unable to part with the Brystons despite their obvious redundancy in my system. Never heard the Krell, though, so I can't make a direct comparison to that well-regarded piece.

Good luck.

That should say 16.5K balanced for the Brystons. Please excuse the typo.
