I was building amps from STK modules. I studied the mating surfaces.
Ideally metal to metal contact is best, even the anodized surfaces
should be milled down. So I was taking the STK module and
sanding it down flat. It really wasn't very flat. I had to start out
with a flat surface for the sandpaper! After much work, I got it
to the point I felt was OK. Even a flat etched surface is worse than a
mirrored
flat surface. Very very little grease is needed if everything is smooth
and flat.


They don't suffer from thermal problem when mounted conventionally, with a
dab of heatsink compound, so why bother ?!!!

All a bit OTT consuidering the STK modules don't sound that great in the
first place.
