Best interconnects for Velodyne DD series

I have DD12 and am using an XLO VDO ER-2 with single input and "Y" on the output since the DD12 has R and L inputs.
I don't belive that this cable is made any more but I am sure you can find a comparable if not better in their product line. They can "Y" any cable they make. I tried Wireworld, Syergistic, AQ and tara when I bought this and it was by far the most noticible in bringing out Bass definition.

Thanks Guys!
From your response Truth Link from Harmonic Tech will propably be sufficient.
I thought (in writing this thread)
a particular "sub-ic" might exist that would improve.

Many Thanks!

FWIW, for years I have run various subs I owned with various interconnects. The past couple years I used the Blue Jeans LC1's which are good low capacitance (and low cost) sub cables. For the first time, I disconnected the Blue Jeans and took some old speaker cables I had never used and connected them from the speaker terminals on my amp to the speaker level inputs on the subs. What I hear now is deeper and better bass than I heard from these subs before, better integration too.

I did a fair amount of research and in the past I have alwas used audioquest's top of the line silver cable. This time I got 2 f113 and needed to get xlr sub cables decided to try Blue Jeans cables. So far so good. Not sure silver really helps with a sub.

The above the kimber hero is not shileded or the right cable I would not use that in my experance sub cables do make a difference to a point, not nearly as much as other cables. Also you have to have a SUB cable they are constructed with a shield to avoid humm and generally are alot tigher sounding then if you used something else.

I use a set of sub cables made specifically for that purpose by Synergistic Research and they are excellent. Tighter, faster, deeper, more accurate and also more musical than a variety of other sub cords I tried. Synergy is obviously critical here and its whatever you like in your system. Cost is rarely an indicator of synergy, as the posts above illustrate.
