Hi Greg , I have used the graham slee Era gold V and have tried the moon lp 5.3 . I am not familier with the ps audio . Both the graham and the moon are highly praised units . I sold the graham slee era gold V and now have the newer version the graham slee Reflex era gold . It is a good deal better than its predessor or the moon and is well within your range even new .Check the reveiws . As far as capturing more resolution or nuances in my opinion that starts in the grooves first with the cartridge then the phono pre .I get great resoltion, speed and nuances . The bass is exceptional as is the mids and highs . I use a rega exact 11 cartridge with an rb 300 rega arm (rewired it myself with the incognito wire set ) on a ja michell gyro se mk 11 and am very pleased with its performance versus cost . I know you would be happy with the graham slee.....till the bug bites again . Thats been my experience anyway . Cheers
