Dagogo Review: Construction of the nimble, $2,100, 2-meter Super Focus compounds upon what is given to the Focus, namely a core of three, 6mm British copper for enhanced current delivery, sealed within three layers of anti-static Nylon, which is then covered under heavy-duty, vibration-damping shields of copper for RF absorption, and terminated finally with WattaGate IEC and AG plugs. The Super Focus is endowed additionally with a custom, RF-shielding copper module that houses the WattaGate IEC plug on one end and the AG plug on the other, and then fitted with a custom stabilizer copper module positioned in immediate vicinity to both ends of the cable.
The Super Focus compelled the Luminance Audio KST-150 to produce richer top- and bottom-end contents in driving the 78dB/8Ω, $10,000 Murata ES301 Spherical Speakers, at the same time rendering tonal nuances dramatically more discernable. With the Super Focus, the Luminance Audio-coupled Murata speakers rendered instruments of all variety with increased tonal substance and spatial definition, contributing to the dimensionality of instruments and realism of venue immensely.
Tannoy’s discontinued 95dB/8Ω, $19,000 Churchill Wideband loudspeaker system was auspiciously rediscovered. Despite a meager output of 7Wpc, the $24,000 Combak Harmonix Reimyo PAT-777 300B SET power amplifier had always proven itself as the most conducive amplification choice in its price range towards inducing tonal coherence and meticulous tonal balances from the speaker’s 15-inch Dual-Concentric™ driver. Nonetheless, the Isoclean Super Focus brought a most profound increase in dynamic competence and tonal articulation to the setup, prompting the Combak to propel the large speakers seemingly with twice as much drive and output energy.
The Isoclean Super Focus’ effects on 47 Laboratory’s $26,800, twin Power Humpty-coupled PiTracer CD transport also revealed itself to be a major upgrade to the company’s $1,100 Focus power cable. Whereas the PiTracer realized marginal degrees of improvements from the two Focus’, pace of music quickened when the Super Focus’ were enforcing the operation, and instruments’ tonalities became more vivid. The fact that such performance advancements took place in a venue where the digital signals were not going through digital-to-analog conversion pointed to either a sizeable reduction in AC noise as delivered by the Super Focus, or merely that the twin Power Humpty’s that powered the PiTracer were given more potent flow of electricity to work with.
Audio Note’s $34,350 DAC5 Special and $36,800 M8 Phono preamplifier also manifested more pronounced tonal distinction and more punctual dynamics, amidst a collective foundation of sonic excellence that was superior to machines I have experienced in their respective categories.
There's plenty more information as well as reviews on the Super Focus out there. This is easilly the finest a/c cable I've ever had in my system (including some excellent cables from Shunyata, XLO, VH Audio, TG Audio, Crystal Cable etc.). I'm selling it now to finance a new audio purchase. The cable is in "like new" condition, exept for a small ding in the IEC plug, which is reflected in the selling price of $850. http://www.ultraaudio.com/equipment/isoclean_superfocus_80a3_pt3030g_ii.htmhttp://www.6moons.com/audioreviews/isoclean/isoclean.html
