What component have you changed out the most?

If cables are ruled out as a component, then my most changed component is the digital source as well. Amplifier would be my second choice, but not a close second

Hmm, forgot about cables.... I think I still have had more digital sources than any types of cables.

Digital Source - four to one. But not anymore. The
Electrocompaniet CDP is THE ONE.

Actually I've stopped changing digital gear as well, not because my Classe CDP-1 is THE ONE though. It's very nice for digital playback, but I've realized that analogue is THE ONE. Neither my Classe or my Sony SACD sound as good as my inexpensive analog rig. I'll probably start concentrating on upgrading the analogue components now. I still listen to cd's, but only when I'm too lazy or busy to clean and setup an LP.

Ignoring cables, which are by far and away the winner here, digital sources followed by amps. Interestingly, no real changes in the amp since 1990 and with the digital sources since 1994 (have done updates and mods to existing pieces, though, to scratch the upgrade itch).
