Lift. Elevate. Rise.
Applied to cables, these three words all end in small tweaks lined with forum ridicule. The tweaks could be free paper cups from Starbucks. They could be the costly engineered solutions from Furutech above or Shunyata at right The underlying notion is that freely suspended cables perform better than those which snake across the floor. Recently Roger Skoff, ex chief of cable firm XLO, published a small piece on this contentious topic. He'd found a YouTube video whose presenter measured a cable's capacitance on the floor, then lifted up more and more sections of it. He accompanied each incremental lift with another measurement. Voilà, the cable's measured capacitance value kept lowering as more and more of it length was elevated.
It's an uncontested fact. Of all dielectrics or insulators, the best is none. Zero is hero. Hello fresh air. When God still used cables—she's gone wireless since—Tara Labs took the air dielectric cable to the max. This became a naturally very dear vacuum cable. God has unlimited funds. Mortal reviewers like Jonathan Scull who actually heard it said it did the opposite of suck. Back to cable lifters, Skoff's article suggests a reason for why they work. By surrounding a finished cable with air on all sides, we don't add to its self capacitance by making our floor an extension of the dielectric.
I've experimented with jerry-rigged Ikea elevators. Then our listening den had exposed concrete floors, later generic wall-to-wall carpeting. The synthetic fibers definitely benefited even if the main cause was probably an escape not from Alcatraz but their static field. The concrete floor benefited less. Later I received eight Audio Physic magnetic cable isolators. By then our big system was on parquet floor and is so once more. Now I hear no difference. Having said gizmos, I simply use them for cleaner routing. Since reading Skoff's article, I've gotten suspicious. Is this German device too low to the floor, the latter still too close to the cable?
In lieu of their cable risers, I reviewed Furutech's GTO-D2 NCF passive distributor. NCF is short for Nano Crystal² Formula. It's Furutech's take on a piezo-electrically active powdered compound. Akiko Audio, DR Acoustics, Shunyata, Synergistic Research and Verictum all have their own formulae. Furutech's enhances their top sockets, outlet plates, connectors and power distributors. Their NCF-enhanced passive distributor had outperformed our older plain Furutech passive. Their two NCF Clear Line parallel 'filters' had proven unexpectedly efficacious. As Caelin Gabriel's ferrite compound factors in the bases of his Shunyata DF-SS cable risers, NCF figures in Furutech's whose segmented risers allow different heights. That suggests that their action isn't limited to just the extended air dielectric effect. The nano compound adds ultrasonic noise attenuation and static removal, the weighted top piece mechanical damping.
Furutech's Graeme Coley had originally solicited me for a review of their cable risers. Given my Audio Physic past, I'd switched him to a GTO-D2 NCF. Why revisit cable lifters if I'd buried the subject long ago? Dead is dead. Zombies only roam in Hollywood.
Now I doubted my knee-jerk reaction. Skoff's article had added a very plausible explanation to the riser aspect. With it, a question rose on my Audio Physic tweaks. Might not Furutech's variable height going well beyond theirs – um, elevate the difference delta to suddenly matter? That wasn't yet counting the additive NCF action I already knew from the GTO-D2 and Clear Line. When I thought back on exactly why I'd turned down Graeme the first time, it's because then I'd still viewed his Boosters as purely mechanical lifts. In my mind I'd belittled them as overkill Starbucks cups done up in metal just to spend unnecessary coin. In hindsight, I had actually overlooked their piezo-electrical aspect and not even considered what added height might do. Was it time I revisited the subject, a possible rise of the living dead be damned?
Graeme was game again. So was I. Here I'll add that some solutions are purely mechanical. Others like Synergistic's above add 'proximity activation' of proprietary solutions; in their case whatever is inside those red 'tuning' dots. Furutech and Shunyata add high-frequency noise traps. Shunyata favor a soft suspension, Furutech go hard. Furutech champion a broad contact patch, Shunyata and Synergistic a minimal edge. Only Furutech's erector-set solution allows height changes, then let's one combine flat and concave cradles in various ways to account for different cable diameters, sleeve entire power plugs, even support multiple cables on different tiers. I've seen cable lifts done up in wood or perspex. DIY could go wild on many other materials. Even folks with two left thumbs could tie up some dry twigs into mini tripods.
Clearly, this game has many variations. Is one a loser if one refuses to play at all?
Ever since I installed Hifistay's Mythology X-Frame rack in our upstairs system, its resolution has shot up to magnify differences it previously couldn't. Did this make room for the potentially finer action of cable elevators to now matter and make their point? My mind had broadened sufficiently to allow for that eventuality. Old dog, new tricks? Sometimes chains need to be yanked.
