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.

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.
POSTSCRIPT
I replaced the AQ Alpha Snakes with Monster Interlink 400 Mk II. They make everything sound better, but I still have the balance problem. Next stop, new CD player.

Thanks for the advice.
was wondering how old your cables(speaker and ic's)are? i use 8tc and 4tc with kcag ic's. i know this has been a long, hashed out, ongoing issue. but when my system was new i had problems with it being too bright and a little lacking in the bottom end. i went out of town for a week and left my system on at a pretty loud volume level with the cd on repeat to break in\burn in my equipment. to my suprise it did make a huge difference. many people say it is impossible/crazy and many say it is true. but i have to agree that cables break in and smooth out over time.
OK, so now that I have sorted some other stuff out, trying the Behringer DEQ 24/96 was next up. Yesterday, I picked one up at the local Guitar Center. Nicely priced at $279.

I was under the impression the unit came with the microphone, which mine did not. Though, after a bit of digging, it seems that the microphone must be purchased separately.

My question, what is the microphone recommended by the folks here?

Once I get up and running, I'll be able to lay out what it did for my systems - good and/or bad. I have one room that has some serious issues, and this guy might be the ticket, if it is as good as promised.
