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.

Thank you for the clarification, Grant. Makes sense...

Sherod, your feelings are classic "silver versus copper" debate. There's not a lot that can be added to what you said, except my own experiences. For a time, I liked adding silver in, and at a certain point, a threshold was reached where it became too much. Yes, it did all of these things that looked great on paper, yet I could never sit down and fully relax while listening. One day, I switched out the silver loudspeaker cables for copper, and there was peace. I learned an important lesson. Depending on system and personal tastes, silver or copper will be better. I've really come to appreciate the liquidity and warmth of copper.

I tend to hear silver plated copper exhibiting a lot of the characteristics of silver. Sort of a poor man's silver cable, though I'm sure some cable company who markets this kind of product for mega bucks will jump on me for saying this.
Since you ask for" budget" ICs opinions, evidentally you are not ready to switch your new bought components, I would recommend replace your kimber 4tc& 8tc even thought they are good speaker cables but bright.I used budget Ics from : Harmonic tech, Audioquest,Kimber for my Krell 400xi. Kimber PBJ ICs as well 4ct and 8ct speaker cables are beautiful in high frequency for dark systems but can bleed your ears with bright system as your Bryston,Triangle and Sony. I would try Kimber Hero ( 160.00 1 meter). Warning: very dark at first but after brake-in period will smooth the low out) then move on to speaker cables . PS audio allows 30 days free trial for their PS Xstream statement. Best wish.
