Pass Labs Amps - Does the heat bother you?

I am very intrigued by pass amplifiers (NOT the intergateds). I have heard many good things about them. However, I also have heard from many people that they get really hot. I am interested in the stereo amps.... like the X350. 

Curious, if you own one or used to own one... how do/did you deal with the heat? I wouldn’t want it heating up my living room where the AC runs more (which kills my music enjoyment session). 

Also, I usually leave my  amp on from 5:00 pm till I go to bed (anywhere from 9:00 pm to 12 am). Not sure how that would come into play if a pass labs would be a good fit for me.

I have a pair of X600 monoblocks in a moderate size room, and they do heat up the room if left on all day, something I don't do.

I turn them on about an hour before a listening session so they get adequate warm up time, and of course turn them off after the session.

I have never felt uncomfortably warm during a listening session.

If it ever becomes an issue, I would run a room AC ahead of time and turn it off while listening.

My pass 250 integrated get warm in my small listening room. I have 8 amps to work with, so Pass in winter and use my other amps when it warm. I recently purchases my first class D monoblocks, and at 300 watts each, they barely get warm. So maybe a second amp for milder weather?

A few rude individuals hereno. I think the question is valid, as I have owned, and still do, some very hot running class A amps. My response: it depends.

I have a XA 25 in a 325 sqft room, N SoCal, not an issue. Even consider buying a second one for dual mono set-up.
