(your power bar or power conditioner could be the source of all your audio issues)
Other Audio Equipment:
Etymotic custom earplugs <== if your ears ring after concerts or clubs and you go out a lot, save your hearing
Xnor's Graphic Equalizer component for Foobar. It is a very well implemented tool.
Instrumental mainly. Original blues. The original jazz masters. Electronic experimental and ambient. Rock and roll from the 60's and 70's. All the music that flowed out of the Mississippi delta basically.
A good solid desk top computer you build yourself. Cheap, powerful, reliable, configurable.
Looking forward to the craziness, frustration, and pure pleasure ahead.
