I second TLS's recommend to read articles written from a sound scientific perspective. The Audio Critic (
www.theaudiocritic.com) is a good e-zine with some PDF reprints of select back issues with important articles. I still sometimes check out Stereophile or The Absolute Sound at Barnes & Noble just for a chuckle, but the reckless subjectivism those periodicals represent has gotten completely out of hand. $500 power cords? Please! Placing magic bricks blessed by Hindu gods or some such atop your amplifier, elevating cables off the floor, or putting silly pieces of wood hither and yon...pure insanity!
As you've discovered, you can have immense fun in this hobby without spending a king's ransom...and by sticking to science, you can put your money into things that *truly* offer tangible benefit. Monster Cables and Mpingo Dots ain't where it's at!
