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)

Audio Consulting Mipa. 2x30W. 2 battery. No heat. I have one for sale. It needs a preamplifier with very low output impedance or passive with transformers.
The First Watts are sick good (I have the M2)…Man, I would keep it if at all possible.
Buy one of those small refrigerators and put the amp inside that. Cut a hole in it for the cables and seal it off with a rubber grommet. Problem solved. Just make sure you run a dedicated line directly to the fridge so its isolated from your system, and don't forget to put cones under it.
Bojack I'm inclined to agree with you. I'd keep the First Watt compared to the other alternatives suggested. Not so sure they will sound better than the F.W. J2.
Just a small correction- the J2 does have negative feedback.

OP: Ayre and DarTZeel are the two A/B amps (cooler) that don't use negative feedback. The latter has a new integrated with built-in DAC which might interest you.
