Walker Audiio High Definition Links prevent very high frequency electronic noises (which are emitted from all electronics) and RFI from being transmitted to your speakers.  They eliminate the unwanted noise from the signal path, while allowing the pure music signal to pass through unaffected.   

The music will become more natural sounding.  The electronic glare will disappear.  The sound stage will open up to become better focused, more transparent.  Harmonics will be cleaner and clearer.  Dynamics will be faster and sharper, without harshness.  You will never know what your system can really sound like until you try them. ​

Reference Plus HDLs are the newest iteration of our very popular High Definition Links.  These areunique, ultra-fast high frequency filter networks that use special proprietary high-speed, nude components to remove RFI, EMI and distortion from the music signal.  Freed of noise and distortion, your speakers will reproduce the music with much more clarity, dynamics, transparency, focus, speed and soundstaging.  You will hear more information without grit or glare. 

What is the difference between the Mark IIIs and the Reference Plus?
Reference Plus HDLs use ultra-precise components and are fully shielded.  Both the Mark IIIs and Reference Plus use ultra-pure silver wiring and spades. Reference HDLS are subjected to a slow-immersion cryogenic treatment and then precisely matched in pairs. The results are absolute phenomenal.  Your choice of Mark IIIs or Reference Plus HDLs will be determined by the quality of your system.  The better your system the more you will benefit from the Reference Plus.

IMPORTANT: It is important to note the polarity: red to red, black to black.  Do not let the copper body come in contact with the speaker cables or the binding post.  If necessary, use paper tape – not electrical tape- to isolate the HDL body from the bare binding post.  It will sound best if you position the HDL so that the leads extend up or down from the binding posts and the body is as far away from the binding posts as possible. 

Biwireable Speakers – Using one set of speaker cables with jumpers:  You will need one pair of HDLs and one pair of jumpers. The jumper wire is critical. We recommend our Walker Audio Silver Jumpers. They are cryogenically-treated ultra-pure silver solid-core jumpers. Your ears will love you.   

Biwired and Tri-wired Speakers:  One HDL required for each speaker cable.

Subwoofers:  Benefit dramatically.

Allow twenty hours play time for the High Definition Links to break in properly.
