Isn't it likely, in most cases, people will thank the current speakers are the best, it's true in my case? Would anyone trade in speakers for something worse? Accepting that in some cases, your choice might be wrong.
My current speakers are certainly the best, Daedalus Audio DA-RAma. Are they the best ever speakers, of course not. They look stunning, which matters if you have a significant other. The case is beautiful solid hardwood, with dove tail joints. They just sound right, designed to sound like live music, I think they do.
Having retired, I could not really afford an upgrade anyway, but I am very happy to keep these, till one of us finally falls apart.
