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.

I recommend Harmonic Technology Truthlinks. The Triangles are revealing and so is the Bryston. Though I like them both quite a bit. At any rate, as long as you have this combination you will probably want a cable to help smooth it out. Especially with the Sony as a source!

To be honest, I agree with a lot of the previous posts, you should'nt really spend too much on a cable, that is until you get a better source. Your source is the top of the chain and no amount of manipulating the signal will cure it. Whether that be cables or EQs.

FWIW

Harmonic Tech and Acoustic Zen both are Robert Lee creations so I imagine similar sonic signatures...

Also, my own 2 cents, is that every electronic component has a sonic signature so get rid of as many as you can in the stereo chain and get closer to the truth, simplicity is the best way to go
I have not listened to the Behringer EQ, and have heard that there are "good" EQs out in the world, but MY experience, which includes the AudioControl, is that an equalizer is the surest means to destroy the sonics of a high end audio system that I can name.

In short, they do everything I rail about preamps for, taken up another order of magnitude. What they subtract (dynamics, immediacy, slam, clarity, refinement), and what they add (noise, distortion, hash) is a combination I want no parts of.

Again, I have not heard the Behringer, and have been "assured" that good EQs do exist, but if there's one thing I espouse in audio, it's that simpler is better. And, adding another component into the audio chain has proven to me in all but a VERY few cases, has only continued to strengthen that view. Maybe the Behringer is one of those special cases, but I'd have to have that proven to me.
