bryston 4b sst- could you or should you turn

Does it sound bad to you when you listen to after it's been off?

Not a problem. The Bryston will last a lifetime.

Turn it on when you want to and don't worry about the small benefits of leaving
it on 24/7. The amp should sound good immediately and improve for about the
first 30 to 45 minutes.

If you want a "green" amp you can leave on 24/7, then you need to
consider a digital/chip amp. However, you should only consider amps that
double power output as loudspeaker impedance is halved so the performance
will equal the performance 4B SST into all loads.

IMO.

Tvad,
Please explain further about (However, you should only consider amps that

sorry for the lack of knowledge,still trying to move into higher end audio.

Actually, Gary, I was mistaken. The 4B SST does not double power as speaker impedance is halved. Caught me by surprise because I was certain the 4B SST doubled power.

When used with speakers that have a significant impedance curve, i.e. low impedance in the bass regions relative to higher impedances in the treble regions, the result is less volume produced in the bass frequencies relative to the high frequencies. What one hears, then, is a "tipped up" or "bright" sound because the highs are louder than the bass.

However, this effect can be ameliorated by using a speaker with a flat impedance curve.

Gary,

It is fine - it will warm up fairly quickly. I never leave mine on except when in use and it generate loads of heat when I use it. The only thing I leave on permanently is my DAC1 and that is because there is no switch - LOL!

Don't worry about turning on and off a Bryston amp. Bryston's are built like a brick and also sound great after only a few minutes of warm up. I have had mine for three years and never leave it on when not listening to music. I don't think you can go wrong with the 4bsst.

Tvad, aren't you talking about amps with high output impedance? The Bryston's output impedance is low enough relative to a speaker's impedance to not be an issue.

That's a good question.

I have 8 ohm nominal speakers with minimum impedance of about 4 ohms. I know my speakers display significantly more balanced music reproduction with amps that double power as impedance is halved (Pass XA-60.5, Belles 150A Reference, Belles 350A Reference, Bel Canto Ref1000) versus amps that do not (NuForce Ref9SE V2, VAC Musicbloc 160, Atma-Sphere M-60).
