i've learned about audio, good sound, and a fine appreciation for what i have, and how good it can get : ]
I've heard amazing systems at meets, i came along way i believe, and this point as my interest and experience developed, i can truly appreciate the quality of gear i have, how it sounds, and it is exactly and pefectly what i want out of an audio system.
I can say this from having about a years worth of upgraditis when i started, to settling in what my stuff about 8 months ago (with small parralel shifts in perhaps cables etc) I love my setup.
I also met alot of real nice people that give me advice in many ways (and i see have patience in dealing with my annoying posts)
true appreciation for this place.
