Tried the Oval's on Spendor, Martin Logan, and Von Schweikert. They sounded really bad on everything to me. The AP cables seam to have a house sound that is not to my taste. If you wanted to spend $$$ on name brand cables that will sound different (dark, cold) try Audio Quest. If you want to save some $$$ and experiment try two runs of 12AWG CL-3 rated OFC installation wire to each speaker in bi-wire configuration. It will be very cheap to try and will likely sound better than the AP Oval.
Good luck!
