Are there any tube amps that don't give off any---

Thanks guys, but like I stated in my OP, I dont want to consider Class D amps, at this time. 
@atmasphere  curious as to what you would suggest in Class D that rivals tubes for smoothness and detail, I can only think of one amp that this may apply to...the Jeff Rowland.

I hear good things about the Element, Purify and a few others.

Hi Ralph, what happened with your prototypes? Any closer to your class Ds?

Daveyf, my understanding is that Carver amps run cooler than most.
I am not sure if you can do this but, if you have a basement you can do what I did which is to make a shelf 12" under the floor and drill a few discrete holes to run wires. I also run fans. I put pots on the supply lines so I can control fan speed. I can slow them down to the point of not being able to hear them at all upstairs. Check out my system page.

"I don’t think you are ever going to find an amp that runs totally cool.   There is electric flowing through it and that is going to generate at least a little heat"     Correct!      All gain devices will generate heat, while in operation (none are 100% efficient), but- not all gain devices are defined as, "THERMIONIC" (requiring some heat to operate in the first place).      The operating parameters of one’s gain devices and how much output power is being called for, will determine how much heat finally results (aside from a filament’s contribution), while signal is being amplified.      ie: Some tubed Carvers = cool enough to touch / some FirstWatt (Class A, SS) = too hot to touch (for the sensitive)
