Ironically I am indeed going back inside in the next few days in an attempt to see if I can determine how many pre-assembled modular parts are involved and their sequence of installation. Intuitively I believe the GUI module and power button go in first then the balance of components in as few as one or perhaps as many as 4-5 sub-modular assemblies. All of this with an eye towards exactly as you suggest, ie; better sound accompanied by what I believe could also be a small but significant lowering of internal temperatures via removing the 6-layer (3 layers inside/3 layers outside on top, bottom, front & sides of case) insulative and magnetically attractive plating process and replacing with black anodizing which is chemically 'etched' into the alloy surface .002"-.003" rather than piled on the surface like plating and completely inert/oblivious to magnetism. Even a half-hearted temp differential modulus attempt shows the potential for a 12-16% reduction in heat and I personally believe closer to 20% may be at least possible. And if I were to attempt it and everything goes south in a banana boat, ie; no increase in SQ, no temp-reduction, I'm out about $100, a week without the unit (I have multiple back-ups) and end up with a one-of-a-kind Devialet 200 that's out-of-warranty (an inevitability anyway in 5 years) with the same surface texture as the volume knob on the remote and anodized black that'll never show another fingerprint, smudge or reflection. Where's the down-side!?!
