On May 21, 2008, five months after purchasing my very first turntable (a Rega Research P3-24), I decided that my obsession with LPs had grown to the extent that I could no longer function without a good record-cleaning machine. I'd done some research and found that the device best suited to my life and wallet was VPI's time-honored HW-16.5. I was certain, anxious, determined. But that morning, when I gave VPI a call, the line was busy. When I called again in the afternoon, the line was busy. When I called again in the evening, the line was busy.

Since its founding in 1993, Colorado-based Ayre Acoustics has made its name with amplifiers and preamplifiers based on truly balanced, solid-state circuitry that didn't use the ubiquitous panacea of loop negative feedback to produce linear behavior. Their first digital product was the D-1x DVD player, reviewed for Stereophile by Paul Bolin in February 2003, which offered unusually good video performance. The D-1x was followed by the C-5xe and DX-5 universal players, respectively reviewed by Wes Phillips (July 2005) and Michael Fremer (December 2010). But the most intriguing digital product to come from Ayre was the QB-9 digital processor. Reviewed by WP in October 2009, the QB-9 has just one input, USB, and uses Gordon Rankin's proprietary Streamlength code to give asynchronous operation, which in theory offers the best jitter suppression. "The QB-9 isn't a computer peripheral," said Ayre's marketing manager at that time, Steve Silberman. "It makes computers real high-end music sources"—a statement with which WP agreed.
