I sold a bunch of guitars many years ago when I had stopped playing. Alot of that money went toward a high-end surround sound system.
FWIW in my situation, I think it was a bad decision in retrospect. My old receiver is sitting in a basement corner, replaced long ago. As does the associated gear.
If I still had that gear (including a really nice 335, a Boogie combo, and <gulp> my first CU24) I'd be enjoying those quite a bit today. While I still enjoy music and movies, newer equipment is always cheaper, looks / sounds better etc.
I guess speakers might be an exception to that in some regards. But for me, I think it was a bad decision. Just my 2c...
