Bi-Wire with two pairs of speaker cables

Yep, that works fine, just don't accidentally short the two terminals.

@hifiman5 

Thanks for chiming in. I appreciate it. This is good news. Any downside?

My speakers are Revel F228be, and Amp is Ayre VX-5 Twenty 

@thyname - I have tried this, but to my ears the only thing that improved the sound was replacing the little mettal strip-jumpers (those generally supplied with bi-wire speaker terminalss) with a quality jumper made from  wire.

Bi amping ia a different approach that can definitely improve sound quality.

One tweak that often improves sound quality with a biwire speaker (using quality wire jumpers) is inserting the +ve wire into the H.F. terminal and the neutral wire into the -ve L.F. terminal. Strange, but effective!

Other that have tried this also reported improvements

One quality wire that I use a lot from Take Five Audio is this one...

It's a 12 gauge wire, but they also have other gauges available
- e.g. I have used their 16 gauge wire for the +ve jumper and their 12  gauge wire for the neutral jumper with noticeable improvements

Hope that helps - Steve

Interesting concept Steve @williewonka I do have quality jumpers (Cardas Clear, soon to try Crystal Clear Magnum Opus), but you are saying crossing them ? So one jumper from High Frequency Red, to Low Frequency Black? The other one from HF Black to LF Red?

@thyname - nope - you install the jumpers across the red and black terminals as normal (red to red and black to black). But when you connect the actual speaker cable, you conenct the red wire to the HF RED terminal and the black wire to the LF black terminal.

Hope that clarifies things a bit better :-)
