I asked my dealer about it today. They called the distributor, who said it was supposed to be here already, but won't be here for a few more weeks. They also said that Arcam is contemplating launching it at CEDIA before they'll allow it to go to dealers. I don't know when CEDIA is, but that may delay it more.
I saw a British forum where a few guys had it already. They said it's better than the CD17 and pretty much on par with the CD37, which is Arcam's top CDP.
The CD37 is an excellent CDP to my ears, so I guess waiting a little longer will be worth it. I'd have pre-ordered the rDAC today, but my wise dealer didn't want to take my money without a definite date and me hearing it.
They're ordering one for me to demo. When that happens or they get official dates, I'll post here.
