Built a phono cartridge cable RCA to XLR interface box to drive the RIAA Phono capability in the dspNexus 2x8. It is a fully balanced phono interface to the coils. Setup with 47K Ohm resistance load and nominal capacitor for the Shure cartridge in the tonearm.
I put in a few different grounding modes, so testing it with the Oracle Delphi MKI and Linn Sondek LP12 should be interesting.
Welcome to the balanced-line phono playback club. And yes -- to the naysayers -- it definitely is an improvement over single-ended RCA connections.
