My Reimyo DAP-777 does reclock. So.. does the Sonos mod add anything?
Does a DAc that Reclocks Remove Jitter from Sonos Connect
I asked Wyred4Sound what the advantages would with their upgrade to my Sonos Connect given the external Reimyo DAP-777 20BitK2 DAC and lossless streams that I use:
Response from Wyred4Sound:
“The Sonos digital output is rather jittery, the mod removes this jitter by reclocking the output from a buffer with far better timing. Based on your Reimyo DAP777 DAC, you might want to opt for the 44.1k modWhat you will find is more clarity, true timing on attack and decay, larger sound stage, etc.”
So ..After more research here is what I found about my Reimyo DAP-777 20bitK2 reclocking:
“For the past few years, JVC has been producing the exclusive Extended Definition Compact Disc (XRCD),using the company’s proprietary 20bitK2 A/D converter during recording, with the Digital K2 machine regenerating resultant clock signals for transferring to a magneto-optical disc. The 20-bit disc is then reconstituted again via JVC’s 20bitK2 D/A converter, then converted into a true 16-bit signal using the K2 Super Coding machine.
The Harmonix Reimyo DAP-777 DAC, incorporates the JVC 20bitK2 D/A converter IC."
Bottom Line: does the Sonos W4S mod add anything to what this DAC already does?

mp3? on Sonos? I only use flac from a linked 2Tb NAS or a lossless Deezer service account. I did one experiment when Deezer went lossless on Sonos. I played a CD through my Mark Levinson No. 37 transport and my Reimyo DAP777 DAC and compared it to the same source being streamed via Deezer lossless through Sonos Connect with Bridge using the same Reimyo DAC-- easy to switch between them- No audible difference. Some of the remastered CD's on Deezer are actually better than my old originals. This is not hard proof of anything but it suggests that the story is not simple. |
mzkmxcv seems to have it right. After considerable additional online research I found another excellent discussion forum with informed contributors that explains that digital jitter (unlike the analog jitter of vinyl and tape) relates only to frequency modulation, has nothing to do with stereo stage or presence and is lost in the noise floor of any decent modern digital recording. In simple terms, digital jitter in an actual music recording or digital stream is virtually inaudible except under very rare circumstances. https://hydrogenaud.io/index.php/topic,109948.0.html |
As stated above: JVC's Digital K2 machine regenerates clock signals ..The Harmonix Reimyo DAP-777 20bit K2 DAC incorporates the JVC 20bit K2 D/A converter,The core of the K2 contains an exclusive process in the generation of an analog sine wave, which facilitates the outputting of a full, 20-bit analog signal at the output terminals. Ergo it reclocks with known efficacy. |
