I am a big fan of these banana connectors because they have plastic shields to avoid shorts, easily twisted ends to lock, and they can stack:
I recommend using a single speaker to try bi-amping, Revel tests their speakers in DBT's with a single speaker. It much easier to listen for differences.
With these bananas, you can remove the straps connecting the high/low sections and then just switch between the stacking and using two channels for bi-amping at the amplifier. I can switch in < 10 seconds.
With some I amps and my Salon1's and Salon2's driven by the Parasound A21 the difference was apparent in a SBTs. This was easily identified in separate SBT session with to a couple of friends I brought in for listening sessions. However, I do believe any benefit involves specific speakers and amps. Some may experience no benefit. It is good to test in your system and draw your own conclusion.
I also recommend, splitting the signal with a Y adapter to avoid DSP based bi-amp processing in the processor. Run all tests using pure direct.
That may seem strange to some, but take a look at most processor reviews, the measurements are performed in direct mode and often specified that way as well.
Why..because that yields the best measurements.
Ultimately, you may use processing but the goal is to remove as many variables as possible.
