Reminds me of a joke a very clever girl engineer used to pick up a similarly clever guy engineer in college (yeah, that whole school were rutting like rabbits -- made it hard to concentrate on studying):
Girl: "Do you smoke? "
Guy: "Yes."
Girl: "Use more lube."
-ium is an interesting thing though. Titanium, Lithium, Sodium, Calcium, Magnesium, Iridium, Curium etc etc.
Without the "i" those would be Titanum, Lithum, Sodum, Calcum, Magnesum, Iridum and Curum, which would be just silly
So Aluminium is completely logical
It was actually very easy to rebuild the large T2 with the DC/DC converters. Used same daughter board layout as for as for my modified T2, only had to move one hole 50th. I also have plenty of space since I only use one and not three output transistors and I found some nice spots for the daughter boards. One channel has the DC/DC converters and the other the newly made 01N100D/LT1021 boards. Both channels seem to work OK.

Now it's late, done for today.
Just picking up on this thread. I've used chassis punches, hole saws and (ugh) forstner bits depending on the size of the hole and thickness of the material. And only on Al. They key thing with hole saws and forstner bits is lots and lots of lube.

I don't know why I love stoner so much, considering I've never partaken (on purpose anyway).
But I do.
The problem is, it's an interaction thing, so each chair is going to sound different in your room. You're just going to have to buy a few (not more than one or two at a time, presumably) and try them.
The most important part (besides comfort, of course) is the material combination closest to the head/ears. I would completely discount anything hard (like solid wood). Cloth materials and suede would be good, but they may make sounds boomier than they were originally. I would also seriously consider something with no or minimal head support.
Yes, I'm always on the lookout for a chair to tighten up the bass, sweeten the midrange and gave the treble more clarity. Something that also makes the soundstage more holographic and gives instruments a less artificial tone would be helpful too.
