When the new version was a step back..
 

I have not yet experienced this, but suspect some have. When have you “upgraded” to the latest version of a component, cable, or speaker only to find the net result was a step backward?

I read that some successive versions of the Watt Puppy were deemed by some to not be steps forward. However, I felt my transition from Sasha 2 to Sasha DAW was a significant step forward.

Yes and too painful to describe in detail. Charles

Switching to bikes, my utility bike was downgraded all around except for the frame in the new version that came out a year later, nobody brought it, the bike co took it out of their stock. I guess the same thing can happen in mid/hi fi. Sony came out with their first BA in ear, I thought that's interesting I'l buy it, and it was just treble, with no mids or bass. Their H3 in ear was a rich feast with a huge sound stage, but almost zero mids, not that I minded at the time.

Not audio related. 718 Cayman.

Audio - can’t think of any actually
