Avnut, It is my understanding that the 830/850/860 Wadias used a filter algorithm that rolled the top about -1 dB at 10k, and -3dB at 20kHz. Perhaps no bad thing for many systems and recordings. But with 49 yr old ears I need all the help I can get up there, without of course introducing any digital nasties. The EMC-1 MkII measured flat to +0.1 dB at 5k, rising to a small peak of +0.4dB at 16kHz in a Scandinavian test (probably an inaudible bump, but at least not rolled off, eh?). Indeed it sounds very detailed yet ultrasmooth. My Parsifal Encores sport modified 28mm Dynaudio tweeters, which, at that size, are probably rolled a bit above 15k too; perhaps my Aleph 2 monos are a bit soft at the extremes, as well. Last thing I need is a rolled CDP.
I'm unaware of any improvements in linearity that the 831/861 might have, but it doesn't lack air in your system then it may be the optimum CDP for you. It's all system synergy, I guess. Keep us posted with your comparisons. Ernie
