Your Experience with Bryston 7BSST.....

I need to replace my B&W MPA 810 MonoBlockcks, used to drive the Woofer Sections of my INFINITY BETA. Unfortunately, one has gone South, and B&W aren't disposed to repair them, and in spite of schematics, I'm having no luck getting them repaired. SO...this brings me to the BRYSTON 7BSST. I understand they are outstanding in Current Delivery and other "Bottom End" aspects that might make them a good choice for this application. I've seen the BRYSTONS (various models) used extensively in Pro-Sound/Touring P.A. systems, and know their reputation for reliability. I've had no exposure to them in "Home Audio" situations, and that's what this query is about: Could any of you Out There on AudiogoN share your First-Hand Knowledge of the BRYSTON 7BSST, particularly regarding the Low End ??? Thanks !!!!!!

My buddy has Betas, went from a Bryston 4BST to a pair of Sim Audio W-10 monoblocks for the woofers. I have asked him to respond to your thread...

Hi Uncajuan; The Bryston 7BSST make great price/performance amps, they can be found used for good prices and are definately built to last. I am Sutts friend who bought the Simaudio W10's. I played with a few different amps before settling on the W-10's. I compared my Bryston 4B-ST with a Krell KSA-250 and a Simaudio W-5 (because I was thinking about either MDA-500's or W-10's), the Krell went much deeper and is a high current amp, The Simaudio also went much deeper than the Bryston (but not as deep as the Krell). I fould I liked the higher damping factor of the Simaudio, because it controlled the woofers better. Your milage may vary since you no doubt have different associated equipment, but hopefully this will help you make the decision that works for you. Have fun and let me know where you end up. Tony

Although I don't have experience with the 7BSST, I once owned the Betas and used a 4B NRB for the bass columns. It was OK, but I eventually replaced it with a QSC M3000a. I believe it produces enough current for 900W/ch into the Beta's 4 ohm impedance. The QSC had much better tone definition and slam than the Bryston, and is available at professional musician's outlets for around $1000. QSC has since gone to digital switching power supplies which might be even better. The main thing with the Betas is to use tubes for the mid/twt columns.
