I used Stereophile's loan sample of the top-of-the-line Audio Precision SYS2722 system (see www.ap.com and the January 2008 "As We See It") to examine the Ayre QA-9's measured performance, analyzing the AES/EBU output data in the digital domain. I repeated some measurements using the USB connection and examined the resultant AIFF files with Adobe Audition's FFT analyzer. I assessed only the QA-9's behavior as an LPCM converter; take it as read that all the measurements I discuss refer to both AES/EBU and USB output formats, there being no difference between them…
When someone finally answered my call, I…
