To bridge or not to bridge....

Do you mean that your 4B-st were clipping??? With what speakers???

Dedicated monoblocks will definitely do the job better than bridged amplifier.
If you somewhay sacrifice quantity over the quality you won't go too far away towards higher budjet over getting another 4B-st.
For example most-likely if you get VTL MB225 you will stay with the same power and you won't be red-ligtning.

What do you mean "It doesn't have to be Bryston". Keep Canada green, get Bryston. 7B STs is the way to go. Why, anything else (unless it's Simaudio. etc.)simply isn't Canadian.
No I have no relation with Bryston, other than being a satisfied customer. They no have an SST series BTW, for those who must have the latest. Don't forget the music. Good day.

If you are happy with the 4B-ST, I too would suggest a pair of used 7B-ST's (what the heck, a 20 yr warranty). The 4B-ST will not give the same performance level on a bridged basis. If you like to listen loud, you will be hard pressed to find more performance for the dollar (i.e., quality reproduction, not just volume). I am also not affiliated with Bryston but sure do enjoy their stuff. Happy listening! P.S. I didn't know about their SST series so can't comment on that (thanks for the heads up Pbb). I guess their next upgrade will be SSST ;-)

I was in the same situation in that I also wanted more power from my 4BST. My speakers were PSB Stratus Gold I’s. I went with a Spectron Musician II (500 watts per channel) and could not be happier. Not only did I have more power, the sound quality was far superior. I found the 4BST too bright, unnatural sounding and less detailed in comparison. I have since upgraded my speakers to Silverline LaFolia’s and the Spectron is a perfect fit.

Unlike Bryston, Spectron had some prior production problems which gave them some bad press. I have had mine for 8 months and have had no problems. I hear that the newer Spectrons have better quality control. I was willing to trade off built like a tank Bryston, but not nearly as musical, for a Spectron Musician II that didn’t have quite the same build quality as my Bryston, but sounded far superior.

Finally, I have no affiliation with Spectron. I’m just a very happy customer who would like to share my thoughts. Good Luck! Happy Listening!!
