I have a Pass Aleph 5, an older Pass class A amp and it does run hot. Pros and cons are it sounds excellent once up to operating temperature but the cons are that it takes a good hour on to sound it’s best. I’m a New England’s do in the cooler months it’s not a problem but in Summer it can get a bit toasty in my listening room . You just have to decide if the heat is worth the trouble for the sound you may love.
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 would NEVER buy or keep an amp that required an hour to sound ’best’. Maybe OP should start a new conversation: "Powerful Amp that only needs a SHORT WARM UP". "LESS HEAT" Also Desired" I try to get the title to be clear about the objective, so when seen in a list it clarifies things. That makes ecological sense while reducing his problem I don't care how much you can afford it, "Teach the Children Well" |
