* BTW, did you ever listen to a digital machine (CD/SACD player) with the Ring DAC?
Yes, the HDCD capable Arcam 9 and 23 I'm most familiar with, although I've heard other Arcam ringers sing in store demo's prior to their move to Wolfson Dacs. Actually, it's funny you should mention the Ring DAC, the audiophile who finally sold the Sony sa777es replaced it with a 9. The 9 was a warm (literally to the touch) but not a soft type player, with a very different tonal balance compared to the Sony 777(*). I've also heard dCS based systems, but they (or the system they resided in) were a little too clinical for my taste.
(*) the 777 was perhaps a better player than even I gave it credit for. It could in fact sound impressive at times given the right software. Strange, I was one of the rare people who actually thought it played CD at a "decent" level, and that it's SACD performance was also just as "decent" ... but none of us thought it nearly as "resolute" as the massive hype surrounding their introduction. I can still recall how certain audiophiles insisted that it was the best digital player ever made, going as far as comparing it favorably to the Linn CD12 (not even close). The hype surrounding these players was in my experience, NEVER justified. They showed consistent negative characteristics (compression during peak periods & a "hashy" noise floor which fogged-over ALL low level details). My CDP was clearly superior 90% of the time, the 777 10% advantage only evident with native DSD recorded material (but even that advantage could be offset by HDCD to quite an extent).
To this day, l still can't believe how the vast majority (but not all, some actually got it right) of the audio press kissed these players Derrieres. Furthermore, when Stereophile re-classed their digital components list, it further justified the hype, further justifying (to me at least) why the RCL is but a "borderline" useless ranking scheme.
Anyway ...
