The comment about "not reproducing music accurately" in the aforementioned web site was directed towards the resolution enhancement feature of the P-1A.
Upsampling is a related, but different process. Together with jitter reduction, upsampling offered me a clearer, less grainy, much crisper reproduction of the music. I think it's worth an audition if you can stomach the cost. PT does offer a 30-day trial.
In my opinion, however, SOCS is the real strong point of the P-1A. That's where you really appreciate the price/performance advantage of the P-1A.
I own a P-1A and leave resolution enhancement off, but some people may prefer to have it on. It really depends on your gear and your taste. My experience has been that resolution enhancement *can* make *some* music sound "better".
