Traded the Most ?

(1) Isolation components (gobs, both purchased and DIY). (2) speakers (four pairs in eight months) (3) IC's (four different ones as well). (4) amps (three, and still use two in different systems. Still using my first "upgraded" PC's but those are next on the "swap" list as well as speaker cable and I added a DAC instead of changing my CD source which was less hassle (sell and buy) and less expensive, I am also satisfied (really) with the results. I am also just getting back into the hobby after a long vacation. I should have just purchased what I really wanted at the start instead of trying to get by with less and don't plan on any more "gradual" step by step upgrades in the future.

Powercords, interconnects, speaker wire, isolation devices, shelf mat'l and power conditioners. The basic componants I have are very well matched right now, and the cost of upgrade is beyond my ability. The acssesories and tweeks can be as important as a new amp. They have certainly brought out the best of this equipment, and I've stay within 10% of my total investment for all my tweeks and accesories.

I guess I'd have to say cartridges. I've bought six since Thanksgiving. Can't decide which I like but I'm leaning toward one of the Koetsu's.
