They're still highly regarded and sought after by a certain segment of fans, mostly old-school/vintage lovers. You might consider listing them on Agon, Craigslist or eBay- you might get a good price for them. Nowadays the more knowledgeable audiophiles don't think much of Bose, but I won't pile on.

But certainly the proceeds of the sale of the 901's would go a long ways towards the purchase of something vastly batter, either new or used. There are tons of speakers available for <$500 that will kill the 901's, IMOHO.
