Question on a Levinson 27.5 amp

I have a Levinson ML-3 amp in a second system. This is more ancient than your 27.5. I listen to this system about once a month. The ML-3 just goes and goes. I wouldn't worry, just enjoy.

Best,

I have a 23.5 (very similar to your 27.5) for 16 years now. For years, I turned it on and off at the beginning and end of each listening session -- this because it was part of a bi-amped system with a pair of tube monoblocks. So when the tube amps were powered down, I just turned off the Levinson too.

For the last couple of years, I've been using the 23.5 only. I turn it on every morning, and off every night, and the rest of the system stays on. During monsoon season (just ended, with lotsa lightening!) when a thunderstorm is approaching, I turn off both power conditioners and the whole system is shut down.

In all that time (knock wood!) I've never had a problem due to power surges or lightening strikes. And the 23.5 ? Sounds as beautiful as the day I bought it. As a side note, according to the watt meter on my power conditioner, it takes about 5 minutes after turn on for the Levinson amp to settle down to a constant idle current.

The 27.5 was the first of three Levinson amps. That I own and I never turn any of then off, except for when I upgraded to the 23.5 then the 432. Enjoy. 

My Class A amp's power switch is on the back panel, with a standby switch on the front. Made c.1993 and still as sweet as it ever was. The Lev's build quality is surely comparable to my Bel Canto.

What does the maker suggest?

I really couldn't get a straight answer from them, although it was via email, so maybe I didn't communicate it very well. I guess I would prefer to keep it in 24/7 since I feel it takes about an hour of warmup time for it to achieve the large 3D soundstage that I have enjoy. As long as I am not shortening the life span. Then it is not worth it. Thanks for your replies.
