Pass X600 Will it heat my room too much ??

It probably depends on how hot of a room you can take before feeling uncomfortable.

I tried an XA30.5 in my 10' x 12.5' x 8' room. The room's volume is 1000 cu. ft. and the XA30.5 put out 200 watts into the room. I was sweating and irritable and returned it to Reno Hi-Fi.

Your room's volume is 2352 cu. ft. if you have an 8' ceiling. So it's almost 2.5 times the volume of mine. Each X600.5 puts out 600 watts into the room (I'm assuming that the X600 puts out the same). That's 1200 watts or six times the heat in two and a half times the space of my room.

It looks like the two 436 monoblocks put out 360 watts into the room at idle, so about 30% of the heat of the X600.

So it depends on how hot you can take it.

Can you audition them or hear them in their current setup to see what how much heat they put off?

It's not the heat you have to worry about, your electric bill will go through the roof if you leave the on all the time.

I have yet to encounter an amp that put out so much heat that it bummed me out. I have a couple of tube amps with 4 output tubes per channel. One operayes in class A, I am ccertain about that. I freely admit that the tubes get very, very hot and put out plenty of heat I just don't position myself close to the amps, I am at least 8-10 feet away. The rooms seem to handle it well.
I hope I haven't jinxed myself because I now have to downsize post divorce. My new place is quite small she got the house (they always get the house!!)

I hope your divorce wasn't over this hobby. I want a pair of XA100.5's and my wife is not happy about it. So if I want them I am just going to have to pull the trigger and see how it goes.

By the way I had an INT-30A in my listening room for a couple of weeks which is about the same size as yours and has a cathedral ceiling and from a heat perspective I never even knew it was on.
