Product Description

Detailed Instructions 

High Definitions 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.

Referring the R-HDLs, one customer said, “When we took them out…(we) immediately noticed a SIGNIFICANT drop in my system performance…All the magic is gone. (With the installation of the new R-HDLs Plus), that magic has returned.” RP  Click on the Reviews tab to see more customer comments.

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.

review for High Definition Links

  1. I liked it very much. The difference is huge! It feels like being “there”. HE, customer email commenting on Reference HDLs and Eliminator

  2. I don’t think there is a better dollar for dollar investment you can make…the new HDLs were a better improvement than upgrading my preamp! Here is what Reference HDLs did for me: deeper and wider sound stage, improved image focus, blacker backgrounds, less perceived distortion, significantly extended frequency range from top to bottom, midrange (human voices) more real… DP, customer email

    Walker HDL’s are fantastic. I’ve used the different versions over the years and they are an excellent tweak. Loyd is a genius.
