What amp to match with Conrad Johnson Premier 16/2

The information on the Jeff Rowland Model 10 is scanty at their website.

I see it is a two chassis model with a switching power supply.

Does the type of power supply mean that it runs pretty cool during idle?

Also, is it practical to tuck away the power supply out of sight, maybe 2-3 feet away from the amplifier unit?

Non sound related questions, I know, but I'm grateful for the benefit of your experience.

Many thanks for the consistent input

I'm kinda/sorta biased to the tube pre/SS power model for amplification, though my experience is by no means wide.

Any thoughts on a Pass labs x150 or x250 instead of a Gamut? An alternative is a Burmester (good prices here in Singapore). The Pass units run pretty hot; not a trivial concern here in my Equatorial city, where humidity and heat cause the airconditioning at home to run all out and switching on a few extra lamps has an immediate impact on comfort. Sounds absurd, but its true. And no, I don't have the bucks or desire to upgrade my airconditioning/power supply :-)
