How to get balanced inputs working

Lots of music when knob is set to RCA,

Pavpet, that is exactly how the audio horizon dac is designed to work. You do not have a problem.

If you change the transport to dac connection from RCA to XLR, you simply change the input selection to XLR.

Ok will give it a try will pick up a balanced digital cable this morning that's it thanks brf , looking forward to it

The performance of a digital cable, balanced or unbalanced, will often be significantly dependent on the relation between its length and various unspecified variables, including the risetimes and falltimes of the digital output signal of the CDP or transport, among others.

More often than not, it would be desirable to avoid intermediate lengths such as 1 meter, and choose a length of about 1.5 meters (approximately 5 feet) or slightly longer, or, if practicable, a very short length (e.g., 8 or 10 inches or less).

See this paper.

Good luck!
