Walker Audio- High Definition Links- anyone

I use them on my Soundlab U1. My findings are much like Markxii, but feel the bass is enhanced and overall distortion reduced as well.

We also tested Walker HDL on ProAc Future Ones, Vandersteen 5 and Dynaudio Evidence Temptations with nearly identical performance gains in each case.

This is positive (and unusual) in that they appear to be neither system nor equipment dependant.

There is part of the instruction sheet describing how to use one set of HDL's when a bi-wire speaker is used with a jumper, instead of true bi-wiring. Has anyone used this method and does it affect both woofer and tweeter, or just the tweeter where it is physically closest?

I've had them for the past three years on my Dunlavy IVa's. I love them, they do take layers! of hash away and allow better vision into the soundstage. I use two pairs, one on the bass and the other pair on the mid/treble. I have taken them off in the past year just to hear if they really mattered, they went right back on. A must have cheap (relitively) tweek!

Yes I would give a thumbs up as well. After a while you wont believe they are doing anything. Then you will take them off , listen to a few tunes , and put them right back on.

Just bought a pair of HDL Mk 111.
There is an immediate positive thing going on that will only get better as time passes they say.
I use them on Meadowlark Heron i,Cary 300B SEI, cabled with Shunyata Helix speaker wire, Shunyata Aries IC, Shunyata Hydra 2, Annaconda Helix power cord,Furman IT1220 balanced power and a dedicated 30 amp line.
Even with all the upfront conditioning these things work at the speaker wire /speaker connection like nobody's business.
Anyone thinking about changing their speakers ought to try these first.
They just might change your mind.
