"Sensational" is an adjective far overplayed in "fine audio" circles (to borrow a phrase that Bob Levi of T.H.E. Show Newport Beach has been using). But I know of no better word to describe the jaw-dropping sound of a dCS/Boulder/Sony set-up at a May 4 demo in the Theater 2 room of Music Lovers Audio, San Francisco. With the assistance of a full complement of Transparent Audio cabling, save for an all-important active USB cable from Synergistic Research, the MacBook Pro/Audirvana-source system, featuring the Sony SS-AR1 speakers that so impressed Kal Rubinson in July 2011 was nothing short of sensational.

For me, the demo began when John R. Quick of Tempo Sales, distributor of digital equipment from UK-based dCS (Data Conversion Systems, Ltd.), ran up to me upon my arrival. Enthusiastically greeting me and my two remarkably well-behaved terrier mixes, Daisy Mae Doven and Leo Gleesun, he declared, "Jason, I have great news for you."

"I can hardly keep hold of the leashes, John," I said, quivering with anticipation. "Tell me, please, before I lose my grip."

"The new Synergistic Research USB Active SE cable blows every other USB cable I've tried out of the water. You've got to hear this thing."
