This is what his gear looks like

What a silly idea! Heatsinks are intended to dissipate heat, not just look pretty. Obviously an audiophool idea................

Here is a selection of small heatsinks in a sample box from Aavid Thermalloy. There's black, red, blue, gold, natural, and plain. While the anodising may make only a small difference to performance, they sure do look pretty.
I used to work for a well-known power supply manufacturer, their approach with large heatsinks for highly-dissipating linear power supplies was to black powder-coat the heatsinks! As far as I know, there was no study done to determine whether plain, black anodised, or black powder-coated were best. I suspect not very much difference, as others have commented!
