More interesting would be what you bought at what price and how much sonic difference you assigned to your purchases. I do find the general ignorance at audiogon offputting.
Are you asking about my purchase history there? Been on Agon for a heck of a long time, since 2002 I think.
Off the top of my head I bought Thiel 3.7 and then Thiel 2.7 speakers from Agon. MBL 121 omnis, Waveform speakers, Spendor, my Hales Transcendence L/C/R speakers. Also my Benchmark LA4 preamp, my older CJ Premier 16LS2 tube preamp, JL Audio CR-1 crossover for subs, I think I got my Harbeth SuperHL5s from Agon, and recently picked up a wicked deal on a Lumagen Radiance Pro video processor for my home theater. (And probably more stuff). All excellent deals.
Exchanging subjective notes with Agon members played a role in a number of those purchases. Hugely satisfied with most of those purchases, and whatever I ended up selling I got about the same price I paid for them. All good with me, not a regret in the bunch.
