So, I'm trying to digitise some vinyls. I have a big amplifier, and I might just use the preamp in that, but I might instead get the Radial J33. The Radial J33 is a phono preamp, but it has both RCA outputs and XLR outputs. I believe that the RCA outputs are unbalanced line level, and that the XLR outputs are balanced mic level. Which one of those signals should I use to record from? The cables I use will only be 1.5m long, and I am using a Focusrite 18i8. So either I use two RCA to 1/4 inch cables and use those, or I use two XLR cables. Which is the better option. Using the RCA has the advantage of being line level, but XLR has the advantage of being balanced.
In short, which is better:
Phono --> Preamp --> BALANCED Mic Level --> Microphone combi jack input or Phono --> Preamp --> UNBALANCED Line Level --> Fixed gain line input or line input of combi jack if fixed gain isn't quite the right level
