recommendations for amplifiers that don't emit tons of heat

I tried a Krell ksa 150 and while I liked the sound, it was like having a space heater in the room. I now have an Audio research vt100. It sounds fantastic, but it makes the room hot as well. Not as bad as the Krell, but it's still a drag in the summer.

I'm guessing I should just suck it up, but I'm curious what cooler running options there are that sound as good (or better)... suggestions?

Your speakers are pretty efficient, so you could probably get away with lower powered amp, say 60-90 wpc, which should have enough headroom for demanding passages.
Perhaps an Ayre AX-7e? or a McCormack Micro Drive?
I am running a pair of Zu Omen Bookshelf speakers with both amp/integrated. The Ayre seems a little bit warmer than the McC, but has wonderful clarity.

Also the main force that controls the speakers is Damping factor not how much power you have.

Definition. Amplifier damping factor (DF)is defined as “the ratio of the load impedance (loudspeaker plus wire resistance) to the amplifier internal output impedance.” This basically indicates the amplifier's ability to control overshoot of the loudspeaker, i.e., to stop the cone from moving

so you wont necessarily need more power. like my self and gdnrbob said try a smaller quality amp you will be surprised.

I like the latest Krell amps very much and they can be bought here for very good prices. True high performance audio. Class A bias with rear fans that are VERY quiet. Some serious engineering went into these amps and they look pretty good in person. Compared to Pass 250.8 and could have gone either way. Truly. I very much like a higher biased amp. Purchased an Agostino Momentum Stereo amp and it runs very hot but sure is good. Do look at the Krell.

I have YBA amps (signature mono locks and 2 delta). They are barely warm including their heat sinks/fins after playing 6-8 hours. They are very rare to find (French made). I don't know much about the chinese version if they run cool. By the way, I live in Phoenix and don't want any thing that gets hot!
