Yes, it uses IPP320N20N3. Lots of output power. No THD measurements yet for coilcraft.
Changes on PCB: some adjustments on component sizes, added header for external zobel resistor. Better muting circuit. Converted some parts to SMD.

Yes no heating issues. IRFB4227 is not suitable though since I didn't use a buffer.

Ok cool, but have you make some listening of the JLA-800S with Coilcraft ?
Sonic difference with the JA-800D/250D with Coilcraft ?

No listening and performance test for JLE-800S with coilcraft yet.
I prefer the organic sound of T130-2, but it has higher THD.

The specs for each amp are listed on their respective Ebay pages. You can read them and see for yourself...

Some obvious differences are the input sensitivity and voltage gain

I have already read the page, thanks ...

I'm not sure of that ... the PFFB lowered the gain but also changes the sound , only Jlester can answer to my question ...
