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 live in Phoenix and leave my BAT monoblocks on for days.  Each has 12 tubes and I can feel the heat just walking in past my 15 x 25 listening space.  The space  gets warmer when the DAC (6 tubes)  and preamp (18 tubes) and phono stage (10 tubes, I think) are switched out of standby mode.  It's gets a little toasty, but it's worth it. I have a quiet ceiling fan that stays on high speed to help cool things down and my A/C is set to a chilly 77 degrees (That's chilly for those of us who live in the desert).  Personally, if you love the sound, I wouldn't be concerned if an amp runs a little warm.  

@8th-note You should have a listen to the KRELL Duo XD amps. Beautiful 100% Class A and it runs cool, not even warm. Only issue is if KRELL is still in business.

CODA amps only run warm. My current #11 is the warmest of all the CODA amps I owned, #16, #8, CSiB. The KRELL Duo XD amps run cooler.

X250.8 owner here. Would I wish the amp to run cooler? Yes, but it is perfect for along Canadian winter ❄️ the big  bright blue meter actually bothers me at night. I wish theres way to turn thr led off. 

I really love the sound so I cannot seem to change the amp. 

If I were a manufacture I would say to leave them on all the time as you have to replace parts more often. Surge strikes ,brown outs ect. I feel maybe the class d is only ones I leave on. Enjoy the music . I'm near a nuclear lab but they won't let me plug in 🤨
