Did anyone experience Audio Prism's Ground Control

Oddeophile,

You have really piqued my interest in the Walker Audio/AP
combo. First of all, I must say I have sticker shock on the
Walker Audio HDL's. I can not believe that such a small little box with only a couple of parts can cost this much.
Have you had the chance to compare the Reference HDL to the
Mark iii? There is no description on the difference in
construction or sound.

I did get a chance to try the GC rca on my center external
7.1 input on my receiver, and here i did notice a difference. Less glare at higher volumes. However, the sound had less bloom and the sound field was more narrow.
Not getting that warm organic sound that I did on my other
components. I guess I will have to experiment with source
gear for my HT system.

If you have any extra Walker's or AP rca's that you no longer need. let me know. I have a spare AP spade that I can't find any use for.

Scottmac,

Give the GC time to settle and break in on the receiver. I have both versions on mine and the sound stage is quite large to say the least and detailed exquisitely. Yes, the HDL's are not the cheapest thing on the street but like the GC they are indespensable and when you have them on and break in you will never want to be without them. If you don't biwire or biamp its not too bad and I did get them through a dealer if you pm me I will advise you of to contact to discuss options.

The Reference Plus is much better than the Mark III, both my dealer advised (who I trust absolutely) and Lloyd Walker. They do add an additional dimensional benefit the Mark III does not, I am advised. I went for all matched for my system. They are matched super tight, use silver capacitors and parts that are all "nude" internally, then cryo'ed in a specific process, etc. There is I am advised a 10-15% mortality rate in production due to the extremely difficult parts to work with. As I said, I am completely in love with them, though, along with Bud's GC's. Staple in my system.

Give the GC in your receiver time to settle. The standard GC should provide for an enlargement and detachment better from the speakers in your 5.1 presentation when settled in. I think actually on a receiver and source without a true third ground structure they show a larger improvement, at least I thought so, over time. Mine are on their final settle in process this week and will know more this weekend for final determination but I was enraptured this last weekend with a few movies I knew well before adding in the final set of RCA GC's to the system and what I heard was extremely promising and delightful.

Enjoy and take care!

Thanks for clearing that up Odd. At that price I would
much prefer a demo or used pair. So, I think I will be
patient for now.

As for my HT system, i do have an update. The standard
rca GC on both my Marantz B-ray and my DVR had a profound
effect on the sound and now i find them indispensable in both applications. For the first time i actually really enjoyed some live music recorded on my DVR through my Denon receiver. I didn't think this would ever be possible, but the sound now has so much more warmth and an actual sense of PRAT if you can believe it. I highly recommend the rca's on your DVR. It makes regular tv audio so much better. So, it looks like i will be needing at least a couple more GC rca's.

Scottmac,

Gee thanks... here we go for round four of ordering more GC's... Ha, ha! Yup, looks like I will have to add those to my remaining GC list for the cable and also now considering them on the subwoofers. I am considering the standard RCA's for both subs and the cable box. I have "heard" from some guys adding them to a hi def panel also improves the panel display. One step at a time, so now appears I will have to add to the cable. I have an email in to Bud asking about considerations for the subs.

Enjoy!

I made some these myself out of some thick zip cord. I found putting two speaker grounds on each binding ground posts of my amp and then putting two of these on each (Positive) binding posts of my speakers. This gave my system a more balanced and more Life-like sound! So I put two of these on the left ground binding post of my amp and two on the right ground binding post of my amp. Then I put two on the left ((Positive)) binding post of my speakers and two on the right ((Postive)) binding post of my speakers. I found out about the Diy speaker ground tweak here.. http://www.audiocircle.com/index.php?topic=87809.0
