Default Heatsinks...

A little epoxy often works pretty well, Some guys like to add a little thermal grease in the centre of the chip, with the epoxy either side to retain the heatsink...

A small clamp is needed untill the glue sets and there you go!

Default ...or not!

use a proper interface material (grease, silpad, etc.)

then use a clamping bar to hold *any* chip from the backside, if there are no mounting holes.

The poor man's approach is to just "secure" the heatsink to the chip using an audiophile grade rubber band

The little memory heatsinks sold in computer stores fit the small Tripath chip perfectly, and they have a "thermal" peel & stick adhesive on them. The ones I got were a cool-looking anodized blue, and were about $10 for a pack of eight. Running the amp, they do warm up, indicating the heat is flowing away from the chip.

A more geeky solution is JB Weld, a metal-filled epoxy. Geekier still would be to grind up a little silver on some fine sandpaper and add it to the mix. Careful not to get the metal-filled glue on any of the electrical contacts.

But will it provide proper dampening for the heatsink, so as not to induce spurrious vibrations into the audio chain?

I hear AGHSEC's (Audio Grade Heat Sink Elastic Containment) causes some compression in the signal due to its tendency to "snap back" after the peaks and valleys of the wave. I find SAC (Scottish Adhesive Containment) to be a better, although temporary, alternative.
