I can't read french, The cotton insulated wire for the main power cord looks dangerous.

Construction is a little bit..... rough.

They have peeled the plastic off the capacitors then draw all over then in marker pen, looks ugly!

I do like the wooden knobs and switches.

OK dude, let's go over it:
1. Photo 1. Cotton-insulated power cable. Boy, I sure hope he doesn't have any spills in the area!
2. Photo 2. Those two wooden eggs, I'm sure they're pulling some special magic and damping bad vibrations in the amp!
3. Wooden case, because any shielding anywhere affecting the class D module EMI has got to sound bad!
4. Photos near the end. Unshielded fans close to the audio circuitry for the win!
5. Cotton insulated cables--because cotton is full of air and has lower dielectric constant than teflon--never mind that this only holds true in a very dry atmosphere as cotton absorbs moisture--I'm sure he has a dehumidifer in his house on a very high setting!
6. Peeled capacitors. Because the cheap plastic coating makes the sound muddled and the highs squishy!
7. Cryogenically treated wires. Because we can all hear the change; who cares that the electrical properties are unchanged!

I can only agree with 3 - the lack of shielding. The amp seem to have entirely different issues as the designer applies standard good sounding techniques to a class D amp. Very inappropriate.

Your comment is worthless as you fail to adress a single one of my points.

And even if I'm clueless, I'm pretty sure the pro audio people are not, and they're laughing at this as well (with the exception of the usual Russian crackpot): http://www.prodigy-pro.com/forum/viewtopic.php?t=25151

I especially love this comment: "My grandpa tuned the wooden knobs, to the same frequency as his wooden ears."

Oops. Just finished editing it. Your points are largely irrelevant to the shortcomigs of the design. If you mentioned parasitic inductance of the caps, unnecessarily long wiring loops, generally bad construction technique for class D, it would have made some sense.

My point goes to the core issue--ludicrous prices he justifies by useless crap added to this.
