What steps forward were actually steps backward?


I'm always fascinated to read about how many "upgrades" were improvements, and that very few were actually disappointing and could be considered a "downgrade". Are we all so knowledgeable and incisive that all our hardware purchases are always for the better?

Who is willing to admit that their "upgrade" was a "downgrade"?

Sold an Adcom GFP-750 preamp and bought a Pass X-2.5 preamp.
The Adcom sounded better in my particular system! Sold the Pass and bought another Adcom!I know this makes no sense whatsoever, but my ears don't lie to me!
Going from Thiel CS7s to Dynaudio Contour 3.0s. After a year I finally "found my way again" and bought a pair of CS6s.
