M-Audio Audiophile 2496 soundcard is the source. A Harman Kardon HK3480 receiver(soon to go to my dad's newly acquired M22s
), and 24 feet of cheap 16 guage radioshack wire.
I plan on getting 10-12 guage wire, much shorter runs this week, along with an Adcom GFA-555 MKII. I cheaped out on shipping for it since it was international, so it'll be a while before I get it.. the guy who sold me these delivered them a day after he got the money order. A true class act.
I'm still amazed at the bass. They weren't kidding, linear down to 30 hz sounds right.
