This is one of those threads that I hate. I hate them because it requires a accounting of all the stuff I've bought (and only partially sold).
For about 10 years my system was unchanging. Primarily due to a very non understanding wife who damn near killed my interest in audio.

Fortunately I didn't get rid of my gear, just the wife.
List does not count HT gear although one pair of speakers and CDP/DVD has migrated to the HT.
Amps - 5 - still own two of them. Transcendent OTL -> Odyssey Stratos -> Transcendent SC-150 (scratch built) -> Odyssey Extreme Mono's -> R.E. Designs LNPA 150's. Really happy with the LNPA's.
Preamps - 4 - still own three of them. Transcendent Grounded Grid -> DIY/Goldpoint Passive -> Grounded Grid (mods) -> Decware ZSLA (DIY) -> DIY copy of deHavilland UltraVerve (better IMO). Currently no preamp, SB2 direct to amps.
Speakers - 3, still own them all and in use in various places around the house. Vandersteen 2Ci's -> Vandersteen 3A Signatures -> Meadowlark Blue Heron 2's.
Digital Sources (CD/DVD/PC Audio) - 6 and still have 4 of them.

Marantz CD-67 (plus modded version) -> Marantz CD-67/ARTDIO -> CAL Delta/ARTDIO -> Marantz CD67/ARTDIO -> SACD 1000 (stan warren mods) -> Marantz/DIO after SACD 1000 died -> Denon 2900 (heavily modded) | Audio PC with heavily modded Stereolink USB DAC -> Squeezebox 2 (Bolder mods and DIY power supply)
Turntables - 2, Music Hall MMF-5 -> Teres. I think I'm done here, at least with the table. Now as to the arm...
Phono stages - 2, Musical Fidelity XLPS -> Hagerman Cornet
Cables - lots but nearly all DIY. I'm just too cheap to spend big bucks on cables. Hell it was only in the past few years that I began to accept the idea that they could make a difference but I heard changes which convinced me. The most enlightening moment was a Chris Brady's (Teres Audio) place. There were about 7 people in the room and a change was made that most (including me) were unaware of. Several people asked nearly simultaneously what had changed. I was shocked to learn it was a power cord. I was 100% certain that a power cord could not account for the substantial change I heard. But it was repeatable and it made me reconsider what I knew and thought.
Other that tweaking my existing gear I think I'm done for a while. The Squeezebox feeding the LNPA's makes for some mightly fine music and I am pretty happy with how the system is sounding these days. 'Course I've said that before.... and so the saga continues.

I've also been fortunate in being able to audition a bunch of other stuff, due in no small part to the generosity of the great manufacturers we have on AC.
