To Mr. Apex? THD is not a brickwall limit. You may get away with 5% or so at very low frequencies while 1% at high frequencies may be objectionable......depending perhaps on duration?
Not that it matters much, but many of the old-school Tube Amps, like the Dynaco ST-70 were maybe 1/2% or higher factory spec......
So while I'd generally agree.......I'm not prepared to make a brickwall statement.....
As for using an IR device? I worked for 'em for years in manufacturing and they were NEVER able to turn the corner on quality. I have one of their demo board / 'D' amps needing a power supply......Maybe a switcher that I can buy pre-packaged?

Have you tested this PCB for N20? Built amp? How does it sound?Hi M. Mile here they are, with UF4004
What is PRO output on N20?
So I received my NX400 boards the other day and am ready to get started. I'm assuming I can just use the components printed on the solder mask? I have seen different versions of the board in this thread. Mine is the version linked above. Are there any details on supply voltages and bias levels. I have very big heatsinks for an AB amp and would like to run the bias on the high side for AB on this version. Any thoughts?
Thanks the offer Freecrowder. DId you build the amp?
I'd like to find out how it worked out with someone first?
just knowing all is well with the design would be nice. I'm thinking about getting PCB from PCB house as gerbers are available.
I need 4 mono sub amps and one bass guitar amp

Hello Sir. Im getting DC output on NX-14. its almost same as Power voltage. No voltage across 0.1ohm in 0.1V range.
can you please give me any suggestion to debug this problem?
i have shorted SGND with PGND. But not connect any external 10K pot to the Signal Input.
Thanks.
