So, I know that it's yet another cable question, but I have recently changed from a Sony AV amp to a Yamaha RX-V667 and I'm now wondering if I should change the speaker cable. Although I like a relatively bright sound and my hearing's not what it used to be, there's now a little too much brightness. Speakers are Q Acoustics 1030i / 1000Ci /1010i and current front cable is Atlas Basic BiWire (rear is QED Micro, which I think is fine). So any suggestions? Please don't tell me they all sound the same, because they don't! Thanks
