Speakers sound too bright.

Thank you Jeff

Speakers being out of phase was brought up earlier.  I think the emphasis was on individual drivers within one or both of the speakers being wired out of phase.

Sorry if this has already been brought up, but it is a 10 second test.  On ONE of the speakers ONLY, I would connect the red (positive) speaker wire to the black (negative) speaker terminal and the black (negative) speaker wire to the red (positive) speaker terminal.  Just to see if it helps in case one of the whole speakers was wired out of phase.

Regarding Blue Jeans speaker wire, they predominately use Belden and Canare speaker wire.  I have both.  The Canare 4s11 is considered very good by many.  I did not like the Belden quite as much but many like and use it without problem.

np... and as you learn stuff, please post any insights or new questions, for the next person who may run into a similar problem.

It's all part of what makes this hobby fun...   (or extremely aggravating )

Is it worth changing out my Blue Jean speaker cables?  I feel like some of these expensive cables are over hyped.  If its suggested not to keep the Blue Jean cables, what relatively inexpensive cables would you guys suggest.  

You have some very good equipment that outclasses your speaker cables IMHO.  I’ll reiterate my earlier recommendation for these Acoustic Zen shotgun bi-wire cables that at $350 are an absolute steal and should be a big improvement.  I sold a pair of them to someone I think was using Mogami or Canare and was floored by the improvement, and these are so cheap if they don’t work out you could turn around and sell them likely for a profit.  Just do it!

You said your KEF were too analytical/metallic. The KEF concentric driver is not metallic sounding, just the opposite. It's extended but not harsh at all. So, will will never like the ML ribbons. Send them back and get something more mellow.
