Low heat alternative to FIRSTWATT J2 ?

Any Gainclone or Class D or battery power alternatives available? I like the crazy good micro dynamics and rhythmic cohesion of the J2. My speakers are 93db full range. Also interested in AMP/DAC combinations like the devialet or NAD D7050 that meet the J2 performance (those 2 mentioned don't)

I recently got myself a J2 and they don't get that hot. Less heat than a push pull tube amp. I was very concerned about heat given I live in small NYC apartment. But it's totally manageable. It doesn't heat up my room. Make sure to have the amp in an open space. I can keep my hands on the amp chassis without getting bothered by heat.

How hot does the J2 get?
According to its manual the J2 consumes 200 watts. Since it operates in class A it will draw that amount of power essentially all of the time it is being operated, regardless of the dynamics of the music. So the amount of heat injected into the room will be approximately the same as the heat produced by two 100 watt light bulbs.

Thats not that hot imo. The way the op was looking for battery powered amps, I was thinking the J2 was burning down the house

The J2 and F7 are the two I am considering.
