Leave an amp "on" permanetly

I understand that tube amps need to warm up sufficently before they can reach their potential. Is this also true with SS amps? I own a McCormack DNA-1 deluxe, and I hear a discernable difference when listening to my system "cold" versus "warmed-up". Do you also find this to be true?

If so, would people recommend leaving a SS amp on permanently? Could I damage my amp by doing this?

Mrtennis,

You seriously don't hear a difference in the sound when your tube amp is on for an hour, two hours, or more? Are you in the room listening to the system or out on the court?

You might benefit by getting a good power conditioner, one that regulates current. Especially with tubes, its not a great idea to plug into the wall if the power source is subject to noticeable power fluctuations. This can really shorten the life of the tube.

Both my tube amps (Audion PX25, EAR 859SE)and solid state amp (Threshold T-200)dramatically improve once they are hot, and a hot tube technically optimizes tube performance. So, sorry to here about your power situation, please accept my recommendation along with my apology for ribbing you.

Mrtennis,
The Shunyata Hydra-2 is a good conditioner that also regulates voltage anomalies...which you seem to be experiencing. Many audiophiles also use the Richard Grey RGPC 600S and pole pig.

I have a dedicated power line with hospital grade outlets for my Threshold T-200 amplifier. This Class A amplifier runs hot, and the soundstage grows dramatically within the first two hours it is turned on. Same with the Audion and EAR859 tube amps. Even the old (1975)solid state Marantz 2252 improved after a couple of hours, although less dramatically than the aforementioned amps. On the other hand, I heard little difference from the lower end NAD and Rotel products.
