Q:
Your product is quite different from the grounding box solutions currently available. Why did you choose to go this route as opposed to a box?
A: The popularity of ground boxes definitely sparked our interest in grounding. We could have followed the trend and made our own version of a ground box but that's not who we are. With our very first product the G-Clef, we introduced a shielding ground wire that was highly unconventional. The Notepad is another unique product. We aren't afraid, in fact take pride in thinking outside the box to bring unique functional hifi products to market.


Q: Are there advantages to your approach over the established grounding box?
A: We learnt of one major drawback to the grounding box. It will become saturated after about 6 months of use. You have to reset it by shaking the contents of the box and let them rest for a day or two before using it again. Some of the latest versions of a ground box require a connection to the wall to eliminate the saturation effect. That shortcoming gave us pause. We thought, how can we approach this problem differently? Then one day it became clear how the biggest groundig box is really Mother Earth. If there were a direct path between circuit board and earth, it would solve the problem once and for all. Our ground cable is very simple but extremely effective at accomplishing that. Unlike the ground box, it will not saturate. Additionally, compared to ground boxes, our cables are very cost effective. A ground box wooden nut upgrade costs more than the Perfect Ground cable.


Q: On the website you mention different terminations other than RCA. Is that regular or custom order?
A: Usually custom. XLR male, XLR female, AC plug, Ethernet plug, RCA, spade etc.
Q: In terms of the spade, where would that be used? On the equipment ground terminal?
A: Yes, that would be intended for equipment with a ground post.


Q: Are there key positions where you would recommend your cable?
A: A source such as CDP, DAC or preamp would be the first choice.
Q: Do you recommend the use of more than one grounding cable?
A: Yes. We have customers who bought PG/UG for every piece of their equipment.


Q: In practical terms, people with a limited number of AC outlets are going to have a problem with that. Can multiple cables be plugged into a power bar like the PS Audio Juice Bar?
A: Yes, as long as the extension outlet is getting the AC from a different outlet than where your system is getting AC.
Q: How about plugging into power conditioners?
A: No on that. They shouldn't plug into a power conditioner.


Q: You have two versions of the grounding cable. Why?
A: Perfect Ground was the first to market. Our dealers and distributors asked for a higher model so we challenged ourselves for an improved version. Using better copper and different natural materials, we developed the Ultimate Ground. The Perfect Ground uses multi-strand OFC with Binchō-tan [ubame oak charcoal from Japan – Ed.]. The Ultimate Ground uses solid-core 100% IACS copper with a rare-earth element composition. Both Binchō-tan and our rare-earth element have the abilities to absorb RFI and EMI. In terms of sound, both cables remove the haze from the lens. The reduction of background noise makes dynamics, imaging, soundstage, bass, midrange and highs all better. The ground cable doesn't change the sound of your system but rather improves every aspect of it.


Mr. Wong had supplied me with the desired information so I took a quick look at the two grounding cables. They came equipped with upscale gold-plated RCAs with locking barrels. Opposite terminations were a Leviton AC on the Perfect and a Wattgate 5266I on the Ultimate. The website indicates that Schuko and UK1363 are available too. The Perfect utilizes 14 AWG x 4 with PVC insulation. The Ultimate upgrades to Mylar metallic-braid shielding and air insulation. Fit and finish on both was polished and they came encased in a high-quality braided sheath with strategic color-coordinated shrink wrap to keep aesthetics clean. Both are of the thick cable persuasion. The Perfect is 3/8" in diameter and the Ultimate ¾" so while they have a reasonable amount of give to manoeuvre into position, you should be prepared to leave distance behind the installation. Extreme angles and thick cables don't go together well. The assembled system consisted of the Wyred4Sound Music Server and DAC-2 feeding the Tortuga passive preamp into the Bel Cant 200.4 EVO amp feeding the Apogee Duetta Signatures. The Paradigm Servo 15 subwoofer saw full-time duty and cables used were principally the Arkana Physical Research loom. First on the roster was the Perfect Ground which plugged into an unused female RCA jack on the Tortuga preamp. To keep methodology consistent, the Ultimate Ground was employed in the same location in round two to assess differences. A third combination saw the Ultimate remain in its position and the Perfect relocated to the DAC-2 to assess the effect of multiple ground cables.
