you will be ok without for testing. They dont seem to get that hot if you stick to 27ohms.

i used these, just because i had them..
Rapid Electronics - Electronic Components

The pins didnt fit perfectly so i just drilled the holes slightly bigger.

i am very happy with the dacs performance now. with the led mod its very very pleasing to my ears.
I am bulding a couple of drop in CSS modules too ( cascode depletion mosfets) to test. will report back

Thanks adamus.

I might just get clip on sinks, yeh they aren't great, but the case will be forcefully ventilated anyway (12v fans operating at ~7v, push pull).

not sure forced cooling is a good idea to be honest. 5687's tend to be relatively microphonic as a family. both apellizo and i have experience microphonic valves in this dac-end.

you may get a quiet 'ringing'.

I got these today:
TO-220 Heatsink, Small Power Aluminum Heat-Sink, x 4pcs - eBay (item 260481603013 end time Mar-22-10 23:26:12 PDT)

Center hole isn't large enough for M3, but otherwise I think they are a good fit. No need to drill the PCB.

EDIT: Damn.. there is a M3 thread, not a hole..

Thats great. I'll get some. The TO-247 package fits ok?
Adamus, if i get these and they fit i'll stick to passive, thanks for the heads up.

Yep.. Maybe 1mm gap between the pcb and heatsink, but not a problem.
