Not really, and I don't care to either. Love both amps, different tonal characters to be sure. Pass amps sound a little more tubey than the Burmester.
And as far as the HVAC thing goes, it just seems kind of silly to run AC all day long and run a pair of amps drawing 2000 watts all day long in the summertime. The climate here in the Northwest is mild enough that I don't need AC otherwise. Having the XA200.5s on 12 hours a day actually eliminates the need for heat in the spring/winter/fall season.
I'm still loving my XA200.5s. The XS300s have me concerned in terms of heat, current draw on the power conditioner, and price. I probably couldn't listen to music from May through October with that kind of heat, as the XA200.5s are uncomfortable enough during the summer for short listens.
They're not that bad. I think the heat issue is overblown. I've been living comfortably with the XS300 since the beginning of August 2012. I do suggest bypassing any type of power conditioner though. I had a 220 line going into a Torus 60A conditioner and the Pass amps connected to it. It wasn't until I removed the Torus and connected each amp to it's own dedicated 20a circuit that they reached their full potential.

Oh. I don't have the luxury of listening to my stereo for 12 hours a day as I have to work from Monday through Friday away from home. Probably running my KSA-250 for 12 hours per day 7 days a week would make a noticeable difference in my electric bill as it does run quite hot. Since my listening room is 9' underground, it doesn't take much in the way of heating or cooling in order to keep the temperature moderate year round and I never worry about the heat load the amp presents to the room because of that. It's always pleasant temperature-wise to me.
I sometimes leave my XS 150's on over night, but generally turn them off. I turn them on the next day about 2 hours prior to listening. They seem to be at the optimal bias temperature by then. They are probably ready to listen to after an hour from cold start.
Thanks, have the VR Isobases at present. Kevin says this provides 4+ the isolation of the VRs. Am thinking of one of the Ohio Class for under the preamp now but they're really expensive

Hope to upgrade someday to the XP-25 and XP-30.

It's a little early, about 67 hours but the first word that comes to mind is more. Dynamics, slam, weight, detail, even at this stage in the break in it's obvious and I can't stop listening. I've been at it 7 straight hours today. It was very good out of the box, in fact I was up until 2:30am the night it was delivered. Day 2 was a little rough but it has been getting better and better since.
