No idea about the technology but I run my H-3000 with balanced cables and it sounds fantastic. I didn't try the RCA outputs because my best cables were all balanced. You should let your ears be the judge of how it sounds in your system.
Allnic H 7000 XLR out.
Having had a fully balanced system previously and seeing it's virtues, granted some may disagree here, am looking into going balanced again. Phono pre is the above mentioned Allnic H 7000 now running single ended. Is there anyone here with the technical knowledge as to the mechanism the phono pre uses internally to send the signal out using XLR cables. A bit hesitant to go forward mixing a basically single ended unit in the chain with true balanced going the rest of the way.
