this may be a silly question but i just put on some single wired speaker cables , and used the jumpers that came with the speakers. i never paid any attention to jumpers because i always had biwired cables and i just figured 4 posts 4 cables. is there a big difference in an upgraded set of jumpers? i see on audiogon some big cable companies make these jumpers and they are pretty pricey even used for some. does anyone have any experience from stock jumpers to these upgraded ones??
thanks
 
IMO, jumpers make a substantial difference. Then again, I manufacture jumpers... :rolleyes:

Of equal, if not greater importance is how those jumpers are implemented. Typically, one connects the cables to the tweeter terminals and uses the jumpers to connect to the woofer terminals, or versa visa.
Empirically, I've found that the diagonal method of connecting jumpers, as advocated by Audioquest -
[sorry, I'm not allowed to post links as a 'newbie', At Audioquest dot com, go to 'Theory and Education' and click on 'Understanding BiWiring"]
to be far superior, running the speaker cable's positive (red) to the treble's red terminal and the cable's neg/ground (black) to the bass terminal black, and completing the circuit(s) with jumpers.
This is the opposite of what Nordost advocated, cable black to treble black terminal and cable red to bass red terminal and completing the cicuit(s) with jumpers.

(Pseudo)scientifically, one could argue for connecting the hot/red cable to the tweeters hot/red for the highest signal integrity where it counts and the black/ground to the bass to maximize damping.

Dunno what one would do on a balanced/bridged amp, other than empirically test....

YMMV,

that makes sense. the jumpers i have are just metal and only fit one way, so i cant test the cross method. i was actually thinking of making a pair from some speaker cables that are just laying around and trying that. i will read that aq info
thank you
 
Steve,

If I understand you, your links are formed and 'cut out' brass sheet metal that connect the (+) binding posts between bass and tweet, and another connecting the (-) binding post the same way. This should allow you to try the 'diagonal' jumpers. Can you just hook up the links as intended and simply connect your speaker cables with the (+) red to the tweeter binding post and the (-) black speaker lead to the bass binding post?
Looking forward to your impressions.

Regards,
Paul

EDIT: The jumpers in 'diagonal jumpers' are configured exactly the same as in what one thinks of as normal jumper configuration, for bi-wired speakers, for each speaker, one jumper connecting both (+) / Red binding posts, and one jumper connecting both (-) / Black binding posts.
It is the speaker cables connectors that are hooked up diagonally to the speaker's binding posts, cable's (+)/red connector to the tweeters red binding post, and the cables (-)/black connector to the bass unit's black binding post. That is AudioQuest's (and my) preference.
Nordost's recommendation is the other diagonal....
 
I had the SF Guarneris which had 4 posts on the back. I used TA Ref (from '90s) and used the metal post from SF. I then happened to find 2nd hand TA Ref jumpers and thought what the heck...I kept them. A small but notable improvement. There was a big difference between connecting the cable to treble or bass posts...and using the SF metal bar...but the difference was much smaller with the TA Ref Jumper. I ended up keeping the cable on the bass posts...and "jumping" with the TA Ref jumper to the treble...and the TA Ref jumper definitely added a more polished and refined touch to the treble.

I added a pair of Shunyata VTX-11 jumpers to my Aerial Acoustics 7T speakers, and was amazed at the improvement. I was expecting little, and was really surprised at the result.

thank you ill check it out
 
I had some Audiovector Si3s prior to my Raidhos, and Audiovector claimed jumpers in place of the standard strips on the 3 sets of terminals would make no difference, and would in fact be detrimental because the jumper strip metal matched the terminals so was better. Just after I sold them and prior to shipping, my local dealer sent me some Chord Sarum jumpers. Godammit if they didn't improve things dramatically. More air around the instruments, harshness levels down, just a big difference. Even though those jumpers are pricey, I would've gone for them if I'd kept the speakers.
