Little bit "forward" sound - what cables to avoid?

You may not even have to change IC's or PC's to get what you want. You say you don't want tweaks. I don't know if you consider AC receptacles as tweaks, but these can make a large difference in soundstaging. I suspect a large portion of what you describe as forwardness is the effect of sound emanating forward of the speaker. Before spending lots of money on cables that may or may not work, try some Porter Port Ac Receptacles (I think $36). These are actually Wattgate 8300's that are double cryo'd by Arthur. Wattgate 350i and 330i PC connectors will also work similarly. The Wattgates will focus more of that midrange energy behind speaker rather than forward of speaker, I think this is what you're looking for.

Sorry, meant Hubbell 8300 rather than Wattgate. The Wattgate PC connectors are correct.

Are you using any sound treatments for the room? Diffuse the first reflection point on the side walls and see what happens. Also try different toe-in positions on your speakers and move seat forward or back some and see what happens.

OK... try tjhe lengthy and costly way first.... start at the A's and go from there....

or listen to those posts above about the cables listed here... MIT, CARDAS, AZ, SR, etc.

Good luck.
