Keeping your Pass Labs Amplifier on all the time

I'm a proud and happy owner of a Symphonic Line RG7 MK4 amplifier. The amp's designer, Mr. Rolf Gemein, recommends to leave the amp on all the time for best sonic performance. I highly concur. After approximately 2-3 weeks of being left on, the amp's sonic qualities jumped from being excellent to revelatory! Liquidity, transparency and sheer musicality were immensely improved. I once read a post here that says a SL owner, after hearing the benefits of keeping the amp on, kept in powered continuously for three years!

I have a pair of XA100.5's which remain in standby mode until I want to listen. From my time with them, I have learned that after about 1 hour of being ON I am 90%+ on the quality of listening.

No sense in paying the electric company more $$ that can go to buying more music :).

Try the experiment yourself and hopefully you can save some $$.

I keep my pass int-150 on standby. If I will be away a couple of days it gets unplugged

Serious listening requires 1 hr warm up. Until then, I still listen and have never left the room screaming in horror

XA160.5 keep them on standby it only takes about 20 minutes for warmup. Best of Luck

I agree, not really any difference between leaving amps on or off, still takes an hour to sound good, I keep my amp completly off, fire it up from cold, i do this to save on capacitor life more than the power bill.
