I haven't been the head-fi guy that I used to be for quite a few years now, but for any audiophile who hasn't tried head-fi, I'd strongly recommend you to give it a look. I don't have the space nor the money to do any full fledge hi-fi stuff, but head-fi is easily within reach on both accounts. In particular, I'd say that to get the same quality of sound, you'd probably have to spend at least 10x as much on hi-fi equipment over head-fi.
Man... I wish I can go back to my carefree head-fi days where I can just literally bury my head between a pair of cans for hours on end...
