Do you leave your components on 24/7?

Minol, 15 minutes may work with your system but I have found at least an hour of warm-up gets you 75% of the desired sound, 24 hours and you have reached a 100%. A case in point is I had a Musical Fidelity solid state preamp. It sounded so much better after 24 hours of continuos operation! Here is some other food for thought, In regards to Audible Illusions preamps I know that the tubes are always on even when the power button is turned off. The only way to turn the tubes off is to unplug the power cord. Manufacturer claims this will keep them operating for the best sonics whenever you are ready to listen. Not sure how this effects tube life.

We repair technicians who work for the manufacturer love when you leave them on 24/7. Over many years the heat damage to the circuit boards or the brittle fragility of overheated wires in point-point wired amps makes them unrepairable (well, beyond economical repair, anyway) so we get to sell new amps and preamps.

You can always tell, even with the coolest running solid state units, which older components were left on or turned off during their lifespan.

I say turn them off. And if tubes, absolutely turn them off.

I tried Minorl's suggestion of having a glass of wine while waiting for my system to warm up...and I became too drunk to read my morning paper.

Hi Mcintech, thats funny as I was told by Nagras US distributor to leave my PSA amp on 24/7. So was that info given to me incorrect ?( I believe you've posted before saying you are Nagras US service manager)

The folks at SMc Audio recommend leaving their McCormack amps on 24/7.
