Balanced connections to my VPI turntable?

How are your turntable interconnects wired now? What are you using for a phono preamp? If you're using a balanced phono section with RCA inputs and have kept the pickup arm ground separate from the signal ground, you're probably already enjoying the benefits of the balanced circuit. Changing to XLR connectors won't change anything. And many balanced components do indeed deliver 6dB better s/n (or 6 dB more gain, if you prefer to see it that way) when run in balanced mode. For example, here are specs for the ARC Ref Phono 3 SE:

Gain:

Selectable 51 dB (Low) and 73 dB (High) at 1kHz BAL; 45 dB (Low) and 67 dB (High) at 1kHz SE.

(Note that the ARC has RCA inputs only.)

I have a VPI Prime turntable using RCA connection to Parradyme JC3+ preamp.

the preamp is balanced and I don’t know how the tone arm ground is configured. This foolish box to provide balanced XLR is pricey for what’s inside . But if it’s worth some db improvement, I’ll build myself 

If your pickup arm ground is connected to the grounding post on the JC3+, your phono cartridge floats above ground and your preamp is running balanced. (Assuming, of course, that you're using the balanced outputs of the JC3+ into a preamp balanced input.)

This is helpful Cleeds, I’ll test it with meter to see it they are connected.

The Parasound spec doesn’t provide any differentiation on using RCA or XLR ?

i believe the XLR is better for noise rejection, your thoughts ?

thanks
