I also have a VPI Aries with the JMW Tonearm, I have used innerconnects and phono cables(Kimber KCAG and Hoveland) and found a sonic improvement with both phono cables(not day and night but better detail) Phono cables also have a ground wire to prevent hum if that is a problem, of course with the JMW arm you use another wire for ground. Phono cable makers tell you that you need a different cable for the phono because of the lower level signal coming from the cartridge. I don't know if that is true or not but in my system I did hear an improvement with a quality phono cable.Good luck.
"Phono" Cable - Necessary if you have RCA outs?
I have a VPI Aries/JMW 10.5 tonearm, which has RCA outs. I am using a .5 meter Kimber Silver Streak to connect to my CAT preamp. It seems to do OK, but my question is: are there any advantages to using a cable marketed as a "phono" cable, vs. using a standard set of interconnects? I see that most phono cables have the DIN connection, which I don't need, but some are also RCA at both ends. Any thoughts/experiences?
