Which Pass DIY amp for lowest heat + power useage?
 
I'm already looking forward to next summer and wondering if any of the First Watt / DIY amps are especially cool-running? I have a chiller for my place, but it's too noisy to run when I want to listen to music.

North Creek Okara II (~86 dB) but my room is tiny and my most powerful amps are single ended 300Bs good for 7 watts or so.

then F5 - decreased to some 40-45W dissipation per channel

possibly with Toshiba outputs ( ask Zhoufang) , because the will suffer less with Iq decrease

I would be inclined to build a BA2 but use lateral mosfets and bias it around 500mA.

any of them with the power switch turned to off

most definitely something from "seven easy pieces"

there's also a pic of nelson holding a class d amp he designed. there might be a schematic for that floating out in the world.
