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.

Grant,

I have an extra 1M pair of MAS Black I'll sell you cheap.
Email me if interested.

Just for the record, the best location I have found for the MAS Black is on the CD player. I prefer it to the Grey(silver) version. It just didn't sound right from pre to amp, but from audio out on CDp to pre the Black can put to shame many very expensive cables. It is a shame they don't make them anymore.

Sherod/Grant, what is the difference between MAS Black and Grey?

I picked up the Grey at the same time John sold me the 3 Cardas adapters (boy, was I at the right place at the right time for those adapters!?!). The MAS was more or less a throw-in, and a no brainer, as you never know when a cable with such a good reputation, having both RCA and XLR terminations, will come in handy. Truthfully, I haven't sat down to evaluate the MAS Grey on its own yet, to be able to know what it actually sounds like.
