I kind of got lucky to come across some of the stuff i had or kept. High end cables ( companies like transparent audio laboratory, audioquest, and such.) not monster cable stuff. sound isolation cones, black diamond racing carbon fiber plates (vibration isolation products to isolate the tubes basically).tube driven DAC unit(maybe a macintosh ??,cant remember now, was a while ago), but it was expensive at least by my standards. I kept a lil 35 watt sca-35 tube amp, nicer old roland turntable, some misc cables, fiber optics and such. I sold a bunch of stuff at one point, tubes, and whatever I realized I didnt really need. I had a s-video cable that was as big around as your thumb (transparent audio). probly other stuff in there i forget about, most of the stuff in general people dont even know is available. the same people who pay stupid money like 1000$ a foot for speaker cables and shit buy this stuff.
The power cable I use for my vox guitar amp is made with 10g wire, runs around 260$ last time i checked. Just one of the pieces I kept, cuz i did have a use for it.
frikn had a sweet old fisher f-500 (? i think thats the model) all tube powered receiver, pretty desirable amongst audiophiles.
i still have a few misc tubes, stuff that will work in my amp or others. cables, hooked my ps3 up to my receiver with fiber optic. And i really liked the lil sca35 tube amp, from the late 60's - mid 70's maybe? still works good, and wasnt worth all that much.
at one time i really thought it was kool to have all this stuff that cost money, but with spiritual development, at some point one realizes the root is a ego driven desire of oneupmanship.
i have no desire to prove anything to anyone. sometimes the flesh is weak tho haha. Im perfectly flawed, like most.
now my only desire is to grow bud.
