Bi Wire vs Speaker Jumpers

@lak is correct in his advice to you.

An additional point, as you are playing around with bi-wiring (from the same amp) try crossing over the separate runs (hi vs low). This can be helpful as well.

Further, the cables (and amps) don’t need to be exactly the same either, as some prefer to fine-tune the hi and low frequencies. I’ve had good outcomes using completely different cables and amps.

In my experience if my amp and speakers are both Biwire capable I notice the layering is much better, I will strongly recommend to Biwire if both are Biwire capable, If the speakers are the only one biwire, I go buy a good quality jumpers..

Agree with Lak you have to experiment , different system different result....

My Legacy Audio Signature II speakers seem to sound MUCH better single-wired than bi-wired(Krell power amp).  Unfortunately, I only found that out after running them bi-wired for decades because I just ASSUMED they would sound better that way.  I was running with Morrow Audio SP-2 for the high frequency terminals, with an old, heavy stranded Esoteric Audio stranded cables for the low frequency terminals. 

It was only when I bought a set of the Cerious Technology Graphene Extreme cables that I happened to go with the single-wire run and inserted the terminal jumpers.  Whoa, it was an immediate improvement, with much more, deeper, and better bass.  I cannot explain why that would be the case, but it is.  Perhaps something to do with the crossovers or internal wiring configuration.

I have N802's.  I have used them both single wired and bi wired.  The b&w supplied jumpers are very good.  I have a drawer full of different jumpers and they all sound different.  Single wired I prefer Audio Magic cables with the b&w jumpers.

Bi wired, I have used Ocos and currently use DH Labs mainly due to convenience since my winter setup speakers "must" be bi wired.  It saves setup time using the same speaker cables.  I wouldn't say bi wiring the N802's is absolutely necessary.

Differences; bi wired improves timing (not an 802 strength) and image specivity with a more forward sounding presentation.  This can be balanced by careful choice of interconnects and associated components.

Single wired is a bit more laid back and expansive with the cables I use but really, I can achieve satisfactory results either way.

So there you go, it all depends on what "you" like.
