In Reply to: RE: REVIEW: EVS - Electronic Visionary Systems Ground Enhancer Accessory posted by Quint on November 04, 2010 at 14:08:47
Hello to all:
I am wondering if anyone has tried using the EVS ground enhancer
along with those capacitor/resistor RF filters across the speaker
terminals that are being talked in the forums, like the Walker HD
links, etc?
Any comments?

They both work and they both work cumulatively, and in my system at least, they work synergistically.If you can DIY you can do better than the Walkers, IMHO, by making a full R-C-R array. The instructions are here on Tweaks in various posts (mostly by Al Sekela and CDC). If you can't, then try Awe-d-o-phile's version that he sells, which I recall are cheaper than the Walkers.
As to the ground controls, again, the instructions have been posted. If you can't DIY, then buy these EVS midels cheaply at $30 each.
I'd suggest you might also like Alan Maher's CBF line too.

Bartc,
In what sequence do you attach all this to the negative post? Spade against the speaker end of the post, then the Walker or other RCR array and then the EVS GE next to the nut and tighten? I understand Lloyd Walker recommends the HDL be behind the spade between the spade and the nut, not between the speaker and the spade.
I am assuming the GE goes between the HDL/RCR array and nut on the post?

Closest to the speaker body: speaker cable spade.
Middle: R-C filter spade.
Top near nut: ground control spade.
Tighten down as much as is safely possible, and use CAIG Pro-Gold or similar contact enhancing and protecting fluid.
Great, that is exactly what I thought. Thank you so much! I use Kontak which is what I plan on using.
My GE's are due to arrive sometime mid next week. It will be most interesting to hear them compared to the reference AP GC versions I now have. I really do like the reference a lot from the standpoint of details and imaging which, in surround is quite astounding. However, I think they truncate "slam" a bit. I definitely do not note dynamic improvement over no GC in the speakers. I am hoping that the GE will be roughly the same with the Walker type RCR array attached to the upper posts. If so, the AP's go back as I have about 10 days to go or so on my 30 day trial and the cost differential between the reference GC and GE is quite enormous for 4.5 pair.
Thanks again!

As I read here, they are not RCR arrays at all. They are simple R-C pairs.
The R-C and R-C-R arrays are posted here under Al Sekela and CDC, if you want to know how to implement a more sophisticated device. And Awe-d-o-file makes them under the Econotweaks line in a multicap R-C version too.
These are synergistic in my system with the ground control tweaks, so don't eliminate any of them!
Do you still hook this up to your negative terminal if your preamp inverts phase ?
Seems to me, yes. It is the ground which is involved, not the absolute musical phase of the electrical signal. Example - hook up your amp/spkrs with +/+ and -/- as normal. Invert your signal at the source, say a DAC and the phase of the signal changes but not the negative ground in the circuit. Same with an amp that inverts absolute phase. The negative terminal on the output is still the ground as far as I know. It is the input circuit that inverts phase at some point in the circuit.
I would email Ric and ask him to be certain, but from my meager, ancient, electronics class education in H.S. eons ago that is what I would expect from looking at a typical amp schematic.

Anybody have a link to the Awe-d-o-phile version of the walker array? I have read about them but so far have not attempted that tweak. How well do they work?
I have a full set of the reference GC from Audio Prism on my main 5 speakrs in my system now and ordered a full set of the GE versions on Sunday from Ric to add to the amp end of the system to try those out and see how they work in addition. So far, I have been very impressed with the reference version of the GC from AP. They were quite expensive as a set though since I bi-wire and bi-amp my speakers and needed a full pair per speaker which is why I stopped there so far until I found the GE version from Ric. Great find!
I understand Ric is inundated with orders so be patient. He was kind enough to inform me mine should be shipped in about a week due to backlog so it seems everybody is on the bandwagon. Good for Ric! That says something in my book.
At any rate, the AP versions (at least the reference) pretty much surprised me so am looking forward to these with great anticipation.
Oh, one last thought. Many people have added these devices to their amp speaker posts. I use two amps in my set up - a multi channel amp for my center and surrounds all bi-wired except the center and a separate stereo amp for the front L/R bi-wired (for now). Has anyone used these on the negative posts on a multi channel single chassis amp (i.e. one per channel negative post) or just one for the whole amp? Curious. Seems from what I read that one per channel on stereo amps is suggested so, logically, one would expect the same thought to work on multi channel amps as well.
Thanks!
