Fake ad it looks like to me. The real new-model PRs look nothing like that, and the old ones have a black and grey dust cap.
However, if you find some real PRs, they aren't too bad. They'll probably get a little louder than the M-Classes, but won't sound as good. Personally, I'd still go with the M-Classes.
Plus, IndoAudio's credibility has been called into question recently by a respected forum member. I can't remember who it was, but I know I'd hesitate to buy from them.
