Every make a purchase you truly regret?

Look, we've all done it. We read about that special piece of equipment that catches our eye. Every review seems to be glowing--never a discouraging word. So, after several weeks of reading about it but with no real opportunity to hear it, we decide to "just do it," and buy it, probably selling a vital piece of equipment to afford the new piece.

So we buy the new gear, plug it into the system, and bamm! It just plain stinks! No matter what tweaking we try, we can't seem to grow to like it. Now we're stuck, feeling like a "Class A" chump, another victim of the audio press.

Question: If this situation has ever happened to you, did you try to go back to what you had originally, or did you press on, trying something else altogether? Anyone ever start over completely?

Me? I always seem to try something else altogether, and it's starting to get expensive. However, I'm considering starting over completely. I mean, get rid of EVERYTHING and start from scratch. Any thoughts?
