Bargain interconnects to tame treble & boost bass?


Here's the system:
Sony DVP-NS755V
Audioquest Alpha Snake
Bryston B60R
Kimber 4TC / 8TC bi-wire
Triangle Heliade ES

Problem: Sound tilted way toward top-end.

I've done about as much as I can in speaker placement and room adjustments, but the system still sounds too bright and too bass-shy. The treble is also a problem when running the television sound (digital cable) through the system, so, while I recognize that the DVD / CD player is not the best, I don't think it is the primary culprit. (I do plan to upgrade the CD player eventually.)

I sort of suspect that the ultimate solution would be either to replace the amp with a tube amp or to replace the speakers. But both are recent purchases, so I would like to see if better interconnects might make a difference.

Are there interconnects for $200 or less (for 1m), new or used, that would help solve my system's problems? I am open to any other suggestions you might have. Thanks.

Point well taken, Eldartford.

Neither my system, nor my room is perfect. Such a beast does not exist, no matter what anyone claims of their own system/room.

I would like to give the Behringer EQ a try. Again, my experience, sans - Behringer, with EQ devices has been abysmal, but I'm beginning to believe that it deserves my audition with open ears AND mind. At that point, I would be in a better position to recommend its use, or not.
Trelja...As I have commented before, I bought the thing just for the spectrum analyser, and I have analog parametric equalizers which I fully intended to use, based on the spectrum analyser data. But once I heard the DEQ2496 eq results I was hooked.

A few years ago, finding myself in IC hell, I took everything out of the system and replaced it with RadioShacks best. Ever since that has been my "reference" cables. Not the best mind you, just a consistent sound that I can put back into the system to see if the latest wire try-out is causing unusual problems. Highly recommended as starting point, very neutral, not bass shy, not shrill, poor resolution, but reasonably even frequncy response. And yes, even a Music Hall or something CD player would improve system.
You should try a Van den Hull: with those, you are sure to lose any information over 500Hz so there you go to get rid of your harsh treble (if you do not mind losing some musicality as well). I went that way to tame my system a few years ago and it worked really well until I realised it got totally boring to listen to.
