Speaker jumpers

I'd also like to add that I'm a true believer in Transparent Audio cable and have been for years. I'm currentl'y using TA Reference MM2 speaker cable, along with TA Ultra MM2 interconnects, and TA Powerlink MM2 ac cable. The jumpers were disappointing IMHO.

Mine are made with the same wire that's in Ultra MM2

This may sound crazy, but several months ago I was able to obtain a mint pair of Martin/LoganSL-3 speakers, but without jumper cables.  By chanch I had a one foot pair of 6-7 foot paif of the top of the line Shunyata speaker wires, which I have been using as teir jumper wires.  Anyway they work superbly.  It does not hurt that I am using an Audioquest Niagara 1000 strip, along with three quality Audioquest power cords as well forthe SL-3's.  Needless to say but they sound simply increadible.  From the very top to the bottom base it sounds like one seamless audio experience.  

I am using Audioquest Gibraltar single bi-wire on my B&W 805 d2. It sounds fantastic. On the other hand,  B&W 805 d2 needs a powerful power amp to drive it.  I use Mark Levinson ML 11 (50 W) to drive the speakers. ML 11 is a high current amp. The result is more than satisfaction.

Hi,
Save yourself money and time, and enjoy your speakers. I own a pair of modest B&W speakers and their components quality is very good. Otherwise you can also question the connectors, the speaker cables, the preamp to amp cables, wall connectors, and so on, all the way to the transmission lines from the power generation plant. Invest on the basic components that speakers, amp, and reproduction sources.
Cheers
