Low-heat-output amp for Devore O/96

Roberjerman I have considered the Rogue Sphinx, but with the logistics of my setup, I need a separate preamp to be able to connect all my components, the amp has to be closer to the speakers. I'll figure it out.

I would consider the Linear Tube Audio Zotl10MkII which were paired with the Devore O93 speakers at RMAF.  I don't believe the four EL84s would produce excessive heat...

Elizabeth good to see you posting again. Another vote for the Linear Tube Audio zolt10mkll.

Large amplifiers may seem to run cooler, only because they have more area to radiate heat.
The one sure way to know how much heat is being dissipated (at least for comparisons) s the wattage dissipated at idle.
Almost all of the energy at idle is being wasted as heat.
Most SS amps after idle level at reasonably efficient.
Class A and partial Class A are wasting more energy since the idle is at the full level rated at class A watts, even at idle.

Anyway, the idle wattage rating is what to look at.

The  Linear Tube Audio Zotl 10MkII I cannot find any rating for idle wattage on the home page of the company, nor at any review.
I guess tube amp owners do not want to know!

Thanks for all the great suggestions thus far. fsonicsmith, I am responding to your post only because I don’t want anyone to get the impression that the 9/96 is putting me to sleep. I clearly stated that I tend to doze off only when I’m playing background music and reading. I’m always wide awake and engaged when I listen for the music, the 0/96 is the finest speaker I’ve ever had. I’m 65 and falling asleep/napping is now a guilty pleasure for me, I certainly don’t consider it a "problem." And the heating of the room in the summer with tube amps is real, I'm not the only person who has reported this. Not all of us blast the AC constantly, it's expensive and it's also noisy, and I don't like noise in my listening room.
