It should be noted that Gryphon has opted for the path less taken with their PS3 Phono Stage; only a single pair of balanced Neutrik XLR inputs is included—there are no single-ended RCA inputs. Robert Harley states in his Complete Guide to High-End Audio: “Balanced phono inputs are rare on a preamplifier; virtually all phono cables are terminated with unbalanced RCA plugs, not balanced XLR connectors.” I have never owned a turntable set up with a balanced output. I checked with VPI President Mat Weisfeld, and indeed the tonearm of my VPI HW40 could be rewired—but then it would not work with my current reference preamp, which only accepts RCA inputs for the phono stage. To take full advantage of the PS3 Phono Stage module, in terms of signal/noise issues, customers would be advised to look into this possibility, depending on their own turntable design. For this review, I settled on a stereo cable terminated on one end with RCAs, and on the other with XLRs, figuring this would yield a better result than using cheap adapters.
