Hi,In my opinion, speaker cable jumpers yield the best results in sound for bi-amp speakers,and saves alot of money versus buying a second amp,jumpers are 8" or 10",I have 10" taralabs omega jumpers,these jumpers are not listed on the tara net site,they are made in the u.s.a.,they are being sold in the asian markets like japan,where they have more money than since,LOL,I guess there economy is better?,any way,11 months ago I asked tara what was the best jumper they can make?,they explained how it was made and the science behind it,I asked them to make it and send it to me,I bought it!,those jumpers was the most profound improvement for sound on a pair of speakers I have heard in 25 years!,believe it or not, you lose less sound quality with 10" cable versus 6ft or 8ft,the jumper that I have is almost as big around as the speaker cable I have on my other system,its tara the one speaker cables,thou the jumpers dont have the diamerter that the omega gold speaker cable has,it is helexed in the windings of the conductors just the same as the omega gold speaker cable and with the air tubes as well,pretty much a baby omega gold,kinda costly!,but not out of reach for some audiophiles,they are $800.00 for 10",well worth the price!,I defiantly have no regrets!,the omega gold speaker cable of course is alot bigger around than the jumpers as I already said,so the jumper as good as it is,is in no way in the same ballgame as the speaker cable, $24,000.00 8ft retail versus $800.00 retail jumper,wanted to throw that in,incase their may be people out there that might expect that you are getting the omega gold speaker cable sound in a jumper,In a since you are!,just in a smaller scalled down sound,this jumper enhances the speakers in a unique way,spectacular! happy listening!
