I asked a 6Moons reviewer whether an NOS machine would not be better than the oversampling Raysonic.
Having read a number of different reviews of NOS and OS machines, I began to have the impression that NOS were perhaps SET-like (excellent on timing, but a little lean) while OS were more push-pull-like (not so good on timing and a little overblown); but he told me that it all depends how the design is implemented.
Indeed, according to this reviewer, the Raysonic is very close in sound to the NOS Zanden. If that is so, it should be quite something!
He also points out that the Raysonic is a top loader, so that eliminates potential drawer issues.

for another positive review.
However, there is a strong rejection of the principle of ASCR which this asylum member claims is used by the Raysonic, here,

There is also a not so positive review by a Marc Philip (who appears not to like any tube based CDP), but he is also comparing the Raysonic with a much more expensive Classé machine.

Marc PHILIP (said to be an independent journalist), was visiting Rotac électronique inc, a shop or importer in Québec.
In a French language web magazine, he likens its sound to that of the Shanling, and can't understand the present taste for valves in CD players.
He says he far prefers the Classé CD which he claim is more dynamic, having a more realistic soundstage.
Of course, I do not know how independent such journalists are. Perhaps this does point to the Raysonic, being better in an SS system rather than a valve system. However, Classé is made in Montreal and Raysonic is based in Montreal, I don't know whether they may be a little regional rivalry here.
"La comparaison directe avec le lecteur de CD Classé, ne laisse aucun doute, le Classé CDP 10Z est beaucoup plus performant, le son est plus dynamique et pour tout dire plus réaliste, la scène sonore reprend une taille généreuse, avec un piqué sur le piano notamment, qui nous est apparu en tout point parfait et quelle belle extention dans les deux bouts du spectre, il n’y a rien à faire Classé, fabrique des appareils remarquables."
I believe the Raysonic is hard-wired to the tube bases, so that could allow the use of very different tubes from the original ones.
Thank you for this review, I am tempted to buy one myself.
