Yeah, one of my frustrations is the extent to which “the industry” does not provide standardized measurements, particularly since noise (and its absence) is the only differentiator among streamers. Paul Miller has tried to do it at HiFi News, though. Interestingly, Stereophile. which I believe shares the same parent company, does not, and my suspicion is that there is so much money in the industry coming from streamer-centric companies (e.g., Lumin, Innuos, Auralic, Aurender, Eversolo, etc.), that it would shut off a fair percentage of current advertising revenue. (I’m not by nature a conspiracy theory type, but I’ve had a couple email exchanges with Jim Austin at Stereophile that troubled me a bit.)
Regardless, Paul Miller’s measurements of a couple Eversolo products are intriguing: on one hand, the Play, a budget product, measured over 300 psec of jitter, vs. 5 psec for the DMP A10. Of course, both of these products have DACs, and you can’t tell from the published data if the source of the jitter is the streamer or the DAC, not to mention the fact that 300 psec is not bad. And of course, as you noted, jitter is not the only source of noise involved in the nexus between a streamer and DAC.
Finally, congrats on your selection of the Rivo+; Miller’s measurements of the cheaper Rivo indicated that its handling of noise, measured not just by jitter, but also signal to noise ratios, was state of the art, and comparable to products in the $10k - $30k range. So it’s not really a surprise to me that you preferrred it.
