Resolution Audio Cantata Music Center

John Atkinson wrote,while describing the Cantata's DAC jitter test results:  "With the Cantata fed the same 16- and 24-bit J-test data via USB (fig.11), the traces are free from all jitter-related artifacts: evidence for the efficacy of the Cantata's asynchonous USB receiver.  Although I didn't test it, the Cantata's Ethernet input should similarly be jitter-free."

Why? 

I ask because I have never seen a techincal review of ethernet digital input performance.  Now Stereophile joins the crowd of not providing any review of ethernet digital audio, but at least suggests that it might be jitter-free.  But there is no reason for this opinion given in the review.

John, could you provide some commentary on issues realted to ethernet transmission of digital audio?  I know it seems to work well in my system up to 96/24 resolution, using a 2TB Iomega DNLA server and a Denon AVR-3310CI main processor for my home theater and stereo listening room zones.

Ethernet

I based my conjecture on the Cantata's behavior with Ethernet data on what I had found with the Linn Magik DS-I (www.stereophile.com/content/linn-majik-ds-i-da-integrated-amplifier-john-atkinson-april-2011). Ethernet seems to be the optimal way of streaming serial data to a DAC.

"Ethernet seems to be the optimal way of streaming serial data to a DAC." - Something Squeezebox users have been saying for quite awhile.

Thanks JA,

for the reply and reference, I'll look at that review.

 

One thing I've noticed is that ethernet (at least 10/100, haven't tried gigbit) bogs at high-rez multichannel, for that I need to use HDMI as the input.
