Listening to Hi-Rez
As Jason <A HREF="http://blog.stereophile.com/rmaf2008/101208house/">mentioned earlier</A>, I gave 5 hour-long presentations at RMAF entitled "Hearing is Believing—Is Hi Rez Digital the Future of Audio?" To allow Showgoers to hear the differences between the hi-rez masters of my recordings and CD and MP3 versions, I used a system put together by <I>HiFi+</I> editor Roy Gregory for his demonstrations of system tuning—Ayre A7-xe integrated amplifier, Avalon Evolution NP2.0 speakers (which I <A HREF="http://www.stereophile.com/floorloudspeakers/708ava/">reviewed in July</A>, Vertex AQ cables, Stillpoints rack and speaker stands, and Quantum QX4 "field generator"—to which I added a MacBook running iTunes 8 driving a Wavelength Audio Cosecant USB DAC.
