    I am a dumb ass and want to try and biwire my main speakers, just to see if to me it makes a difference.
    I have a Yamaha DSP-A5, with 2 main stereo channels, A+B.

    Is this how i do it?:
    1. Take off metal joining bracket from speaker binding posts.

    2. Connect red (Channel A) to red on speaker top binding post.

    3. Connect black (Channel A) to black on speaker top binding post.

    4. Connect red (Channel B) to red on speaker bottom binding post.

    5. Connect black (Channel B) to black on speaker bottom binding post.

    6. Select A+B chanels, play something and listen.

    Now, can i use 2 of the same cables?(ie non 'biwiring' cable)
    e.g. 1 cable from channel A & 1 cable from channel B??

    Technically what you are doing is bi-amping rather than bi-wiring, but the wiring configuration is correct.

    Bi-wiring would be when you run two sets of cable from channel A, one to the top set of posts, the other to the lower posts.

    You will have no problem using two seperate runs of the same cable.

    Whether this will make any difference or not is a subjective matter.

    Why is it bi-amping? Surely bi-amping requires two amplifiers. The A and B posts are just two sets of outputs from the same amplifier.

    Yeah, they will be safe. I found that my old Yamaha made no difference with A or A+B. Theoretically you are adding more to the signal path using A+B together and could add more interference to the sound, but this is open to debate.

    I prefer to biwire using all eight ends crammed into the A terminals only at the amp end and the 8 at speaker end into the seperate 8 on the speakers. Suck it and see......:)

    It would depend on whether the A/B posts are dealt with seperately in the amp or are just two connections to the same output. If the latter, then it is bi-wiring.

    Actually, thinking about it they are probably the same output, I think I confused the A/B on my amp with the 2nd room output and thought A/B were seperate channels (it's been a bad day :( )
