Do you mean loudspeakers? That is an old design(over 30 years) with Dynaudio drivers, just the shape is similar to JBL.

Thumbs up I looked closely (your "deep" thread) and this.

Bravo , my man !!

Now , how can this sound so good with "contemporary" layout and the fact that it is a modified LIN amp ? I asked this question in developing just such an amp and how/why the little technical refinements would better the sound.

What you listen to might prove the "purists" wrong ? 95% is the circuit itself , short of any real bad layout decisions. You might get that extra 5% by "pulling out hair" (fussing) over layout/ grounding ... but can you "hear" that 5% ?
Might just be technical refinement just for the sake of technical refinement ?
As the output stage gets larger ... these little "technical" issues might show themselves , but- what works .. works!
PS- you have enough room for a dual mono power supply ...
Good job (even the case) true DIY !

Default Junie, from Dubai, has made a lovely amplifier using Precision I boards

I am so proud of it that i decide to dress myself as an Arabian Sheik to celebrate.

Efficient enough, Sakis ? Maybe for 2x100W of output power, but Federmann declare much more higher...
