Besides Devialet how many 99% 'sealed' multi heat generating digital components, ie, amp/pre/DAC enclosures have we seen with no provisions for active ventilation or convection cooling? How many digital amp-only enclosures with no ventilation provisions have we seen? How much can heat can "flow" inside a 99% sealed unit? Is it flowing or is it migrating thru radiation or physical proximity and contact from one part to the next? How many other previous systems can we name that have nearly 1:1 component-to-air ratio internally. Why might traditional systems have have well over 5:1, 10:1 or 20:1 air-to-component ratios internally and be ventilated and Devialet have only ~1:1 and be sealed?
Whatever I discover will be made public here. If it works, great and I'll tell you. If it remains about the same, no harm done and I'll tell you. If it fails, I gave it my best shot and I'll tell you. If I get stupid lucky and the numbers sound too good to be true tell me a word or series of numbers to write down on a post-it and I'll stick it to the Devialet right below the GUI and snap a pic, post it within 5 minutes and show you! No one's been invited or encouraged to follow me along in duplicating this project alongside me. I post it for other's curiosity, entertainment and salient interests only. Personally I make no guarantees but I also know we can argue many things, however success isn't one of them.
As to EMI escaping; if it opens any of my garage doors unintentionally I'll change their code. If my iPhone rings all the time as it did before with a new unmodified digital amp I'll move it further than 5-6 feet away.
Let's try to keep it in the spirit of fun, innovation, adventure and learning rather than painting a doom & gloom scenario before its finished. No improvement ever came from complacency or not trying something. And holes can be plugged!
Actually, there are some positives in the above posts. If you consider that the difference between the 200 & much more expensive 250 is cooling, if you can improve cooling of the 200, then maybe this is a route to actually increasing the performance some way (or all the way) to 250 levels? Although how you electronically reconfigure the power supply etc. to 250 settings I have no idea. Just a thought!
Although it may just blow to pieces, of course!
