Speakers sound too bright.

Why is everyone skipping over this is a dipole 1 foot away from the wall behind them? I dont care how long you burn them in, what treatment you use, the cables, the preamp- NOTHING will fix that "dipole close to the wall behind them" problem.

@lonemountain  The ML speakers the OP has are not dipole, they’re box speakers. 

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!

To rule out a speaker being wired incorrectly internally and assuming you have your speakers hooked up correctly, just play tracks 22 and 25 from this — no need to mess with resistors and such. Left should be left, center should be center, and right should be right and if all that lines up your phase is fine. I continue to think it’s break in, but you should consult your dealer to get their thoughts as well.

The reviews I’ve read of your speakers do not indicate an inherent brightness at all, and your associated equipment also should be fine so I’m thinking additional break in should yield significant improvements.  What interconnects are you using?  BTW, if you’d like to significantly upgrade your speaker cables here’s a pair of Acoustic Zen shotgun bi-wire cables (I’ve used these for many years) for only $350, which is a ridiculous price for these cables.  You should jump on them, and if you don’t like them for some reason you can probably sell them for a profit.

My suggestion would be to restate your question and include as much information as possible such as:  Room, amplification, source, cabling & power conditioning.

@rick_n  +1.  Hard to assess anything without that info along with what speakers you were using before.  Also, 1-2 hours isn’t nearly sufficient — you should give them a minimum of 100 hours to begin to seriously judge them, and they could well improve further to 200 hours and beyond.
