The warranty for Expert and Pro Amps IS five years, as stated in the Devialet web page; it only requires that you register the unit with them. And if upgraded, typically from an Expert to a ProCI series, the five-year warranty period is reset, and starts again. In this case, you have a new unit, with a new warranty.
The Devialet amps use their casework as part of the heat dissipation mechanism. That is why the D250 amps are effectively identical to the D220 except for the case and remote. The thermal management of the D250 is more advanced.
But back to the leak of fluid from the heat sink adhesive; old timers here may remember that before the ProCI amps were produced there there was a member, user name was M something. Mammot or ? He was from New York, I think. Anyhow, he dismantled his D200 and changed the speaker binding posts and also redid the thermal pad from the internals to the casework of the D200. We were aghast at somebody going all Frankenstein on a $10,000.00 amp that was under warranty. I was, at least. Those posts are probably 2014 - 2015.
He did also say that the mods he made resulted in a significant improvement in SQ. He had criticism of Devialet for some of the OEM components, but I recall that the heat transfer stuff he did was notable, as in, a lot more area. The gooey adhesive seems to be an issue in all these things were heat is handled passively. Or in the case of the Xbox, even with fans it was a mess.
I've gone into the weeds again, but this is an interesting issue, and one that is likely relatively simple to deal with. Even if a bit messy. (Now there will probably be a big run on used D120's as we all decide to hot-rod the older amps) .
