Sound-Transforming USB Cabling Layout for iUSB Power and iDAC

Some time ago, a customer of mine, Jonathan Crawford, purchased an iUSB for treatment of the bus power entering his USB DAC.  He followed this purchase up with a trial of the associated iDAC from the importer.  In the course of a detailed telephone conversation concerning the cabling for the same, I suggested a novel cable arrangement whereby the Data portion of the Ultra Fi Basque Usartza Digital Conduit with Integrated Filter Technology completely avoids passing music files through the iUSB thereby eliminating their exposure to power between the Mac Mini and the iDAC.  The associated Figure below shows the basis of my suggested arrangement.

Once Jonathan understood and tried my suggested arrangement, a second, follow-up telephone call quickly ensued in which Jonathan spoke passionately of the remarkable increase in purity and openness that he found quite unexpected and shocking.  In his words, "this is not a tentative/small improvement but a major contrarian break-through!"

From there, we further discussed how the blue cable that comes with the iUSB might be eliminated and I developed the Ultra Fi Basque Power Conduit to do just that - furthering the benefits of this arrangement.  Upon receiving the Basque Power Conduit and installiing it in his system, Jonathan immediately noticed a significant increase in detail accompanied by a perceived increase in volume for a given amplifier setting.

I've decided to openly share this novel cabling arrangement and if there is enough interest, offer a cable set comprised of a Digital Conduit and Power Conduit to those that might be interested.

Please drop me an email through the Contact page if you are, in fact, interested in purchasing such a cable set.
