Would you sell half your vinyl collection to get great equipment ?

To put classical musicians aside, every artist I heard had only a few best releases. As an example, I wouldn't really need Miles' Dark Magus - Pangaea is similar and much better. Pink Floyd - WYWH is the only album I would need, the rest could go. In my case, I just didn't buy what I didn't really need, well, almost.
However, given a bit more of the resources, I would have an Otari or Studer open reel deck, make recordings from vinyl and let the records go except for the most valuable to me. Sound quality would not be worse.

I would - - if I got to choose which records I would trade (I've got a ton of vinyl, which includes a fair number of stinkers and mediocre items.)

Of course, this would be a free choice.

I would never sell my vinyl and i have dozens of violin records worth well over 1k each as they can never be replaced.I was once offered 3k for i violin record and tuned it down,Good luck though.

It's those New Yorkers, they can buy $3k record or bottle of French wine. Either would do.
