The colour would look hideous on the LCD2's but the finish would look great.
Speaking of which, now that I know how the drivers are put together, if one had the right equipment, the LCD2's drivers are quite easy to make and reverse-engineer. Nothing like the insides of the Hifiman drivers I've seen with use of gold/silver coils.
I don't know. Black and red look good IMO. It would look pretty bad with LCD-3's though.
The magnets in those LCD's are pretty tough to setup, as I understand it. But I think you're right about needing the right equipment for it.
