Plinius warm-up

mi plinius sa 100 when I leave on AB for a day, its
sound close to class A mode. I notice If its off.
it takes 2 hours beofr it will perform to its
peak. I class A mode it takes a hour then its audio
heaven the inner detail is next to none.

I have an 8100 and I leave it on all the time. I feel that Plinius, more than anything else I own, needs time to warm up and since I listen a lot, I just always leave it on.

Every Plinius(and so I believe Pass) amp has an extraneous heat sink area for its output elements. This situation is substantially better than having a lack of a heat sink area, but it needs a great amount of time to bring the amp to the normal operating conditions.

Along with it they idle cool and quiet and need no worries that something will burn internally or externally. Moreover no extraneous ventillation or cooling neccessary as well.

My Sim is on 24/7, as they recommend. Even then, I warm it up with music, fairly loud, for 15 minutes or more before settling in for serious listening. The difference is not subtle. Most improvement comes in image and soundstage depth and, well, warmth.

I leave my Plinius SA-102 on in A/B mode all the time. If I'm planning on listening in Class A I flip it into class A and let it warm up for about 20 minutes. If I simply start listening it is a bit harsh in the highs, relitively! Plinius seems to be very sensitive to this issue. If I do turn the amp off or unplug it for some reason it takes a couple days to get back to top performance.
