Dang nabbit! I realized I didn't say it right. The thermal flux does decrease, but the thermal gradient does increase in response to a thermal pulse. Not that anyone actually cares, but I hate leaving my mistakes uncorrected. Less embarrasing than having someone else correct me later!
As much as I hate to say it, brass does have a scientifically documented benefit over copper for vibration and resonance control. Lubricity is only one of several reasons whey bronze is a favoured material for large scale industrial bearings.

With condemning others for doing analysis and gaining a better understanding, probably carefully sorting out choices before even touching the materials, you, Peter, might leave a very ignorant and narrowminded impression.
That's what I would find depressing, someone telling me how and if to think...

i saw this movie, at a theater, after, i was so depressed,
the next day,bought a-lot 'o Cr-4p at numerus thrift stores,
and some caps' n' perf board just to get feellin better.

Choices
Yeah, yeah round the sharp corners of the PCB, pour some laquer over it, C37? Teflon sounding better than epoxy or poly iso-cyanate ester? Or better p2p wiring? It is up to you! Life and engineering is about choices you know
BTW I have a can of Maple juice. What should I do with it?

Quick question for Peter if you are still keeping up with this thread: what brass alloy are you using for the heatsink? Also, what thermal paste or pads are you using? (I think those look like silicon pads, but I wanted to ask.)
I must admit that I am not sold on the "sound of heatsinks," but whether it sounds any different or not, it definitely looks great! So I figured I would try and see for myself how it works/sounds since I have a stash of brass sitting around.
Thanks for sharing!

I'll let you think about this for a while. 
I am wondering if the material is irrelevant but the chip temperature is the factor.
This would/could lead to a different conclusion on 'best' material for every amp/speaker configuration.
I note that many designs (including Peter's) look 'under heatsinked' to my novice eyes. Maybe the secret is keeping the chip at just the right (high) temperature.
