I own a Seta, haven't had it very long. I purchased it specifically to start the process of archiving my very large vinyl collection. I have no experience with other methods of doing this, so can't compare to PS Audio or anything else for that matter. I'm also using a Lavry AD11.
Initial impressions of the Seta as a phono stage have been very very good. I have also used the Seta's flat outputs to the computer and used their Pure Vinyl software for RIAA conversion. Using the Seta's flat outputs was a true surprise. I would have in NO way expected it to be better than just using the phono stage the traditional way. Not only was it better, it was a LOT better, reference quality. I don't have any conclusions at this point other than to say, recording this stuff in PCM seems plenty good enough for me. I would not get sucked down the road of trying to do this in DSD. Lots of technical issues involving just moving the files around. IMHO not ready for primetime yet.
I'll keep reporting back as I get more experience with this. Right now waiting for another tonearm tower to do a second setup dedicated for this purpose.
