Now it was Even Steven, but this comparison did tell me that neither the CD nor the Touch has yet attained perfection.
The treble from the disc was a bit smoother, but even that difference disappeared when I turned off the Meridian HD621 HDMI audio processor's upsampling and apodizing filter. I even ripped a few CDs, to compare the sound of the original disc as played by the Oppo BDP-83SE via HDMI into the 861, with the streamed file from the Squeezebox Touch via S/PDIF into the 861.
Day after day, I continued to be impressed with the sound quality of the system as it played these HD downloads, finding them as satisfying as any two-channel discs.
