Please help - system "brightness" problem

All good advice...plus what may sound initially "bright" may sound different as your ears adjust to a new speaker...and again this might not be the speakers fault...what you often gain in detail can be perceived as bright through poor recordings and electronic matching...it is the "double edged" sword of hi-end..I have not heard the the Tylers but they are highly regarded here and on other sites...good luck...

Joel...I should have said "certain" recordings instead of "poor"... cheers

Firstly, I agree with the above in that you should let the speakers break in for whatever amount of time is recommended by the mfg or dealer.
If that doesn't work, I have two suggestions:
1. The HT Truthlinks are a good cable, but I have found MIT 330 (older, beige version) to be a more forgiving cable for your CD player. The MIT, of course, will not have the resolution of the HT.
2. There is a tweak called the AH! LS Noise Filter, which is a filter you connect in parallel to your speaker terminals that will slightly reduce and clean up the highs. It only costs $50 and is available from Upscale Audio. I tried them on my B&W DM602S2 and got excellent results, but your mmv. The biggest downside to the AH is that I do not think it is returnable if it doesn't work.

Problem solved - thank you all for your great posts. I found that two of the binding posts were lose (from the inside). The small nuts that hold the binding posts in place were lose and made it impossible for me to properly secure the cable lugs. I removed the plate on both speakers, properly tightened the small nuts, replaced and tightened the speaker cables and the problem I was hearing has vanished. Sorry for the post, but thanks for all of your help!! Happy listening!! Joel
