I Need a Power Amp for my Studio Monitors

Bryston are excellent value for power amps. They do run very hot. If "unrefined" implies lacking in coloration then they are unrefined, IMHO. If you like SS designs and are not frightened by the negative feedback boogeyman then Bryston is a solid choice, IMHO.

I've heard the Brystons are good in the bass department, but lacking in the mids and highs. I'm wondering how a Hafler Transnova P-4000 would compare to the Bryston. I see lot's of Haflers in studios too. There's one for sale locally brand new for $500. Would a used 4Bsst be worth the extra $1500?

Lots of Brystons in the recording studio;s for the obvious reasons.Never had heard of them running hot.My 2 didnt on 4-ohm speakers[Missions].YMMV,good luck,Bob

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.
