At about 9 minutes 30 seconds, he starts to mod a 20k Vermeer (Audio Aero) DAC. Damn, it takes guts (or something else) to chop up a piece of gear that expensive. OTOH, while he and a lot of people judge the price of a component based on the internals, he can’t figure out why the Vermeer, with relatively little inside, sounds better than the Terminator, which is packed with parts. All this aside, I think Mike is an interesting guy to watch. I don’t think you can judge the quality of components from You tube videos, but his stuff is somewhat entertaining.
