Burning Burn in question

Thanks for the advise. Not sure I want to both turn the poweramp on AND play at 100% volume :), but I'll hook up the DAC/Pre to my poweramp, keep it turned off and crank the volume on the DAC all the way up.

Dont blow your ears (JK) let us know if you notice a difference after some burn-in!

I'm more concerned about blowing my speakers. I just did this a few weeks ago and was out $1,000 for new midrange drivers.

The current drawn from the dac/pre by your power amp will be well under 1/10,000th of an ampere, and most of the circuitry in the dac/pre has no involvement in supplying it. I doubt that having the power amp connected will have any influence on the burn-in effects that will occur. I agree, though, that it makes sense to have signals going into the dac/pre.

Also, while it is probably very unlikely, I would not totally rule out the possibility that the long-term reliability of the input stages of the power amp could be degraded by exposing them to large amplitude signals for prolonged periods of time while in the powered down state.
