Any regrets in selling gear?

@testpilot Great point! 

The only thing I wish I had held on to was a Bryston BHA-1 headphone amp. It wasn’t my only headphone amp so between the one I kept and the Bryston, I sold the Bryston. 

Fortunately none…but the list of regret purchases is another story.

I guess it depends on your approach.
 

My approach is very deliberate and careful. Each purchase is intended to be a significant step forward and is preceded by lots of research and often auditioning. Over the years I developed rules like never invest less than 2x or more for the next component, and work towards a new system at an optimized higher level… so no weak links. Then I stay there for many years. With this strategy, what I leave behind is always far inferior to its predecessor. 
 

There are many other approaches like just swapping around… checking out different stuff. Etc. My objective is to get the best possible system I can afford… moving in a straight line towards it.
