I Need a Power Amp for my Studio Monitors

Bryston amps are the only amp I know of that has a ten year warranty.

I have some Powerpack 120s (which are among the smallest and least powerful amps Bryston makes) that are over 11 years old, had regular use in a variety of systems and have never malfunctioned, even when used as on-location PA amps with a low-impedance load under terrible outdoor conditions.

Brystons are as close to bullet-proof as any amplfiier ever made - that's why pro studios use them. Having an amp break down during a session is not acceptable.

That being said, current generation (made during the last ten years) are not at all soft or euphonic, so depending on the other gear in your repro chain they can be either too revealing or too matter-of-fact.

Yes, YMMV when it comes to sonic tastes, but in terms of reliability and functionality Brystons are a great choice.

In my primary system, which is also a home theater, I'm using three Bryston 7B ST's for center and rear channel power. I used to use two of them for my main front speakers.

I agree that they are good in the bass, but I haven't found them lacking in the mids and highs. They are reasonably accurate and do not convey any of the lushness in the midrange that is commonly attributed to tubes. I don't recall them ever having run really hot. In this instance, my sentiments seem to align with some of the pros.

I replaced the Brystons in my front stereo channels with a pair of Pass X600's, which cost a lot more. These sound slightly more delicate on the high end and very slightly more detailed in the mids. As Class A circuits, they also run hot for real.

Bottom line, I think Brystons should be perfectly fine with your monitors, and the "unrefined" comment is undeserved. The primary difference you may hear between Brystons and other amps is a more accurate midrange from the Brystons when comparing them to tube amps.

"more accurate midrange from the Brystons when comparing them to tube amps."
Yeah Sure!
