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.

It really depends on your room. I have an X250.8 that I run in a fairly open space. The amp itself gets warm but it doesn’t noticeably heat up the room. If I was running it in a small bedroom it would probably get pretty warm though. 

XA60.5 owner. Not at all. But I have an open space so the amps get as much “air” around them as possible. I guess if you had a small room it could warm it up a bit. However, I think the heat they give off is pretty minimal as long as they’re not in a rack or anything like that. The manual says basically the same thing.

Over the years, I've had a Pass-Labs 30.8, and several First-Watt amps all of which ran hot. The F-W SIT-2's and F8 ran hot as they were class-A as was the P-L 30.8.  The sound was great in all of them.  I presently have an Accuphase A48 also class-A which runs just as hot as the P-L and F-W amps.  At idle or full tilt, they will run just about as hot as class-A is always driving.  The sound is worth it !  IMHO...

Running XA60.8 monos with KEF Reference 1 Meta. They get warm but not hot. I have them on Sound Anchors stands in the middle of the speakers completely out in the open so they get good ventilation. Love the sound quality and the company, the heat and electricity usage are worth it IMO.
