I don't know of any problems with the PH 7. I sure love mine. Just a few months ago, Audio Research came out with a new reference level phono stage. It is spectacular. The cost is dear - $12K. Maybe some of these folks selling their PH 7's are upgrading. If so, hopefully this is another indication that the recession is just about over!
I am not familiar with the Manley product line so cannot comment on that comparison.
