Should Class A Amps be left on??


Ok- Audiogon members need some advice here. Should Solid State Class A Amps be powered all the time? Have heard two school of thoughts on this. Apparently from what I have heard this is a moot question for Class A/B amps due to the usual low biasing of A/B Amps. From what I have been to learn so far Class A Amps should be left continously on.

I keep my solid state amps on 24/7 unless I am going out of town. The soundstage really opens up after they have been on about an hour. I turn off my tube pre-amp between sessions. It seems to warm up fairly quickly, plus I don't want to burn up my NOS tube set.

If you notice a difference and don't want to wait then leave them on all the time. If you have heat/power concerns or ocassional listening habits, then you may want to switch them on in advance of your session.

Be aware that warm up can also be significant when auditioning new equipment.

On a side note, I have 22 Bryston amps at my work that have been on for 10 years straight without failure.

hope this helps,
