Bi wiring v single run w jumpers

Without prejudice to the effects that the absolute benefits
are always system dependent, Some of the high-end quality
build brands are moving away from bi-wiring in favour of
shotgunned runs and jumpers configurations.

Biamping ... Different story.

E.g. NORDOST

"... Many hi-fi and home cinema loudspeakers have two
pairs of binding posts. This allows the speaker to be either
bi-wired using two sets of loudspeaker cable or bi-amped
using two amplifiers.

As a general rule (and there will always be exceptions) we
tend to find that bi-wiring will open out the sound stage
and increase perceived levels of detail. However, single
wiring will often sound the most musically coherent. There
is also an issue with single and bi-wire speaker cables. In
all the research we have carried out, a single wire speaker
cable out-performs a bi-wire cable of equivalent cost. This
makes a lot of sense; the single wire speaker cable has two
high quality conductors and the bi-wire cable requires four.
So for a given budget, we believe that a single wire cable
will always out-perform the equivalent bi-wire cable, so
much so that we no longer produce dedicated bi-wire
cables..."

For me:

(i) in my high-end "A" system, shotgunned NORDOST
Freys with matched FREY jumpers bested all contenders and
pretenders. (including bi-wires) - full stop. The
differences were not subtle. The only thing stopping me from
moving even higher in the NORDOST chain is price and also
limiting returns of the added big-time ka-ching. In
fairness, having matched FREY ICs for synergy with the
speaker cables helps.

(ii) in my more modest "B" system, I actually run
bi-wired sets. I do so primarily as a "pick 'em"
choice between quality silver-plated OCC copper single runs
with matched jumpers, versus, all-Cu copper quality bi-wires
as leftover surplus sets from prior systems.

I did not see any noteworthy differences between them in
THAT system. I retained the bi-wires and sold the
singles/jumper sets as hedge for potential flexibility later
(the bi-wires can be re-terminated into a shotgunned and
jumpers configuration)

FWIW.....

Good stuff I have the oval 9 (newer version ) I have owned for 3 years I owned the original from 2001 to 2011. I think the original my be more pleasing to me even though the newer version has sharper images/
I am on loan with the bi wire oval 12. If we were comparing bi wire and single runs of the same cable ie Oval 9 I would think that would be a no brainer going to the bi wire but we are talking one size of bi wire and one size of single hence the question. It was touched on by one of you.

OK let me ask this One run of AP Oval 9 with jumpers or bi wire (two runs) or Oval 12? I did try this on one set where I could not tie things together inside. The biwire seemed more open and slightly relaxed. Voices where more vertical With the single run of 9 I felt like I was looking at the floor where voices were coming from, so to speak. More airy"

When dealing in areas involving biwiring, jumpers, etc.., results are application specific. You have to try different combinations, and see what works the best. A good portion of it depends on your equipment. My Vandersteen's are probably the best example of how biwiring makes a positive difference. Using 2 separate runs of cables, with them, makes a very big difference. On my other speakers, Wilson's, they don't even believe in biwiring. They feel so strongly about that, they only put 1 set of binding posts on the speakers. I couldn't biwire them if I wanted.

The only thing I can tell you for sure about all this, is to not let these relatively minor cabling issues, compromise or overlook areas in your system that are more important.

I am trying to compare these three sets of speakers on an even playing field That is why the issue is brough up.

3 sets of speakers or 3 sets of cables? If its 3 sets of cables, the only way you can get a level playing field is to try them on the actual speaker you will be using. Cables don't always sound consistent from one speaker to the next. I think you might be over thinking this. AP has a decent reputation for working with a wide variety of gear, and you already own it, so there's no risk. However you configure the cables, I would be surprised if you didn't get good results. It can happen, but I don't think its likely.
