Bi-amp shootout

Newbie to this forum. I just picked up a pair of terrific RT55i speakers...with stands....for $50. Love these! I'm running a Yamaha RX-V667 with discrete amps so I wanted to try a bi-amp test. I set both speakers next to each other; one was single-amp'd, the other bi. I fed a mono source into both and switched back and forth. Verdict? NO audible difference. They sound EXACTLY the same with either connection. Clean, punchy, precise (all good because I can use those extra amps for other speakers). What results have you all had with bi-amping?

    The receiver you are using while technically has several separate amps for each channel, has only one power supply to power all the channels collectively.

    True Bi-amping would employ separate amps with separate power supplies.
    With anything audio though, there is not much consensus on anything.
    You may find some to say either hook up is better or no difference.

    But fun to try stuff out, either way!

    Nice grab on the RT55i - sleeper speaker for sure.

    That's because it wasn't bi-amping, which requires separate power amplifiers each with it's own power supply and the use of active crossovers.

    BTW, a mono source is not a good way to discern much other than tone differences, which is important, but far from all the aspects of stereophonic music reproduction.

    Thanks for this info. I’m wrapping my head around the gear required for true discrete bi-amping vs. the “hybrid” bi-amping sold and promoted by manufacturers (in this case Yamaha). They market it as simply “connect two separately-amplified signals from our device to your bi-amp-able speakers and you’ll improve the sound.” It “sounds” good in theory, but does it result in an audible increase in quality? And my shootout, based on the simple parameters marketed by manufacturers, didn’t seem to result in any change. I guess I’m asking if anyone has had an audible improvement by simply connecting a bi-amp speaker to a stock bi-amp-capable receiver/amp?
