This question is related to the first. I run RCA from my VPI Prime to PsAudio phono pre, and XLR to Rogue RH5 preamp, RCA to the amp. The RH5 has only one XLR input so I used it for phono rather than DAC reasoning that anything that lowers noise in the phono section is a good thing. But is there any point in using XLR in the middle of a line that includes RCAs on each end?
