Help, too bright

I had everything from MIT T2's to cheapo Radio Shack, to Vampire Wire lower end, and DH labs....I never had a problem with noise whatsoever,,,

Its ok to have better cables, in my eyes, due to better quality connectors, better looks usually, and if shielding is an issue as well...but I dont agree with using them as tone controls. Why spend so much on cables,when you can probably just trade in the hardware for a different unit that suits your taste.

I buy all my equipment used.

I absolutely agree with you. Every manufacture has their own ideas of the perfect sound – and there’s tons of fantastic equipment on the used market at around 1/2 off. It’s soooo much fun to mix and match in order create your ultimate sound!

Stands positioned well away from reflective surfaces will help a lot. Play with the toe-in angle and distance to the rear wall.

BTW, fancy cables can make your wallet thinner and more comfortable to carry, but if they audibly change the sound of your system, there's something wrong with the cable design.
Good cables are electrically neutral, well sheilded, have good connectors, and cost about $20.00

1. MP3 is not a high fidelity source and should not be used for critical listening.
2. Interconnects that come with your equipment should not be used. For cd player to amp suggest you try MIT, Harmonic Tech or if you're on a budget, Phoenix Gold 810 (from Parts Express). Avoid the cheap AR cables recommended by Stereophile.
3. Radio Shack speaker cables should be replaced. For low cost, try Canare Star Quad available from Markertek or the CL-3 Monster cables from Parts Express. Search the forums for more info. Even a good ofc copper based 12 gauge cable will probably work as a starter solution.
4. Good speaker stands will improve the sound.
5. After trying all of the above, if your system still sounds brite, suggest you investigate the AH! LS Noise Killer filter for your speakers.

try virtual dynamics cables. the life they will bring to the music will amaze you.
