In the long run it's not very effective to use interconnects as tone controls. I agree with Prpixel, it's probably a speaker/listener placement issue. Alternatively, it could be an equipment isolation problem.
Ic for bass problems
I'm currenty using the following gear: Meridian 507 cdp, Plinius 8150 integrated, SF EA1 speakers, Straightwire virtuoso speaker cables, Onix Maestro ic. My problem is uneasy, muddy, bloated, low mid and bass. I did try for a very short time Kimber pbj ic, and it did rectify some of the problem, but gave peculiar unreal bass. I'm considering Red Dawn ic. Will it help?
