From TT to phono preamp it's always single-ended RCA as this is the standard. It's low gain signal so makes no sense to use XLR.
From phono preamp ...
Based on what I read, there is a reason to use balanced interconnect between TT to phono preamp, it depends on the cartridge you choose, if you use MC, then better use balanced all the way.

Another small benefit with balanced is that it's not easy to pick up interference.. interference can be a problem with the low signal passing through RCA interconnect, so as I heard..

The PHONO 2 CI is an excellent Phonopreamplifier in fully balanced Single-Ended Class-A design. He incorporates beside the regular RCA input which is based on voltage amplification, additionally an XLR TRUE balanced current amplifier input for MC-cartridges.

Both inputs have flexible gain adjustment to match the cartridge with the input-amplifictaion.

Fact:
MC (Moving Coil)-cartridges are balanced current generators and matching best with balanced current amplifiers
MM (Moving Magnet)-cartridges are voltage generators and matching best with voltage amplifiers


The Vinylfriend has here the unique possibility to choose between two completely different amplification technologies. The unbalanced voltage amplification or the balanced current amplification input. Both amplification methods are user adjustable or working automatically. Because of this flexibility there was no MM oder MC cartridge found, which did not sound excellent with the Phono2Ci.
