I'm sorry I don't do this often but I have to brag for just a minute. I bought a Demo model XA-30.8 power amp a few weeks ago and can honestly say this is by far the best power amp I've ever owned. (and I've owned a LOT of amps)
I run the amp above 300hz and at first I wondered if it would be powerful enough but that concern was quickly put to rest. It's a 93 lb monster and I've yet to see the needle move up even when I crank the crap out of it.
No more constantly trying out different power amps for me. This one is a keeper.

I hope you removed that foam in a meantime

I think what you're seeing is a very small piece of foam wedged to hold four small silent fans I put on the heat sinks. They work very nicely as the heat can be felt blowing out to each side of the amp.
All right. I'll yank them out and see how hot it gets. The rack is open on all sides so it does get plenty of air. Mostly I used the fans because I had them anyway for my tube amp.
I think mine runs at around 45C or so in free space with 20C ambient.
I'm curious what temp is yours running at with the fans?
It's certainly a keeper for me, not to mention that I cannot move it
even if i want to. 🙂

Warm but not hot - Those four little fans really suck the heat out. On my day off I'll yank them out and check though. I believe Zen Mod is correct in that fans shouldn't be needed with all those nice heat sinks.
Again I only put them because I had them on my prior tube amp and figured might as well keep them.

Using the fans may affect the bias adjustment, since it was made without them.

Okay yeah I got the message and will remove them. Again I just had the little fans and figured I wouldn't waste them. Amp is open on all sides so should still cool nicely without.
Thanks
