Summertime ss amp Question

Wow those look hot. Do you get any ball rash mid summer?

Why not look at Luxman 800 or Esoteric A-03. These will at least compare to what you have even though they are above your range.

Check out McIntosh's MC7100 power amp, 100 wpc @ 8 ohms, 150 wpc @ 4 ohms, THD @ .005 maximum. I have one, and it runs so cool and would be perfect for your needs. AND it's a great sounding amp. The later models like mine, have balanced/unbalanced inputs, to boot! No meters, or autoformers. Currently they can be had for about $700 or less.

I did, yes. Assuming your question goes to the differences between battery power and wall power, I had 20 amp dedicated lines and battery power was still the way to go. The batteries, even in a highly resolving system, brought no improvement at normal listening levels. It was only during very demanding orchestral passages that the batteries showed their worth - because they provide a very low-noise power supply, the crap/grunge that would normally find its way into the signal path, and which gets amplified very audibly at high volume, is largely absent. The effect is a sense of more natural dynamic range, even though the batteries actually lower available peak wattage. The benefit is also audible with cleanly recorded rock played back at high volume, but mostly, the batteries are for people who are very serious about the playback of orchestral music.

The Rowland Model 2 and 6, if run from batteries and run balanced (i.e., with fully differential balanced source components and preamp) in a well-assembled system, offer some of the very best performance available from solid-state. I sold my Model 6's several years ago (my current amps are a darTZeel solid-state amp and VAC Renaissance 70/70 Mk. III triode tube amp), but have been running a Rowland Coherence II battery-powered preamp in my main system for seven years now.

... fit into 17 X 8 X 19 inch space in Stereo closet and run cool, budget under $2K used.

Is it possible to take the $2k that you're going to spend on a amp (that will most certainly not compete with your wonderful Atma-Spheres) and instead spend it on modifications to the stereo closet that would help the amp run cooler? I ask because...

I recently moved my equipment into a dedicated closet just outside my listening room. My amp is class A, so I was worried about heat. My solution was to place the amp on the top shelf of a tall rack and have the closet ventilated from above with a large but quiet cooling fan. The fan sends the hot air through a duct in the attic to the exterior of the house. A one inch space between the bottom of the door and the hardwood floor acts as an air intake. Even with the door closed all day and the equipment on, the closet doesn't get warm. Total cost of construction work (not including rack): $300.
