Some have complained that the new album doesn't lay new ground, but whaddaya want? The guy's 65, innovation has never been what he and Walter Becker have been about (at least not since the high mark of Steely Dan, which was one of the most innovative pop bands ever), but—more to…

"From a layman's perspective, I'd listen to the 'Audience' mix on my first bourbon and the 'Stage' mix on my second."
Ahh, yes, out of the mouths of . . . audiophiles . . . who like good booze!
Lacking a 5.1-channel surround-sound rig at home, I enlisted the able assistance of "Music in the Round" columnist Kalman Rubinson, who then convinced his son-in-law,…
There are no numbers indicating whether one is first or fifth. If the solo is listed here, it is simply one of the best.

Hansen had mentioned that the QA-9's response was flat to around 1Hz.
"Another thing that we wanted to avoid that is ubiquitous with ADC chips is the brick-wall high-pass filter that is intended to keep DC out of your system. Now, it is good to eliminate DC for a variety of valid reasons, but adding a brick-wall filter will create ringing no matter whether it is a low-pass or a high-pass filter. The Arda ADC chip carries its own similar DC…

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…
