Changing to less expensive gear.

Have you ever traded a good but more expensive piece of gear for a cheaper and better sounding piece?

Comments are often made buy people with less expensive gear that what they have is good enough for the price. The implication is that more expensive gear does not provide better sound.

So this question, hopefully approaches this from another angle. I have never sold higher priced gear to get better sounding cheaper gear, but I'm not saying it cannot be done. What has been your experience?
