Should I try to improve speakers at $2000.00 range

This thread demonstrates one of my pet peeves. I should say at the outset, that I am not singling out Johnnyr or Dayglow. But, I have to ask Dayglow has he ever owned a pair of Sl-700s? Has Johnnyr heard a pair of Sl-700s since "back in the day"? I own a pair of SL-700s, as well as other speakers. You may agree or disagree about my assessment. I don't know whether they are better or not as good as the Silver 17.5, because I never heard the latter. Relying on aural memory from 20 years ago, probably with different source components or amplification, or based upon what you may have read about other speakers is largely meaningless. It seems obvious that answers to these types of threads many times are responses based upon what that individual currently owns and rarely based upon actual comparisons. Rant button off.

if it ain't broke don't fix it...leave well enough alone and pay attention to improving your listening space
{room acoustics}..tell us about the room is it treated?

I can understand your passion for the 700s with the right
system they can sound A! superb.
I sold Celestion loudspeakers for over ten years SL 6 SL 12 SL 600 SL 700 and know what they are capable of.

With what Zoot45 owns now with his existing Quicksilver Rega electronics which I am acutely experienced
in this scenario even you would agree the latest Vandies together would serve his Systems Performance and music best.

If you like the speakers you have, that's a very difficult question; especially when there are so many different flavors of speakers, and you can't possibly know which flavor you like best without "auditioning".
