Is it nessasary to have a USB converter w/ NAD M51
IS IT NECESSARY TO HAVE A USB CONVERTER WITH A NAD M51 DAC?
I'm using my Sony XA-5400ES as a transport for most CD listening. I use a Toshiba computer directly into the Nad 51's DAC USB port It sounds good but would a converter (like a Stello U3 or something like it) make a difference in the sound? Would it sound better or just different? Has anyone done a comparison with and without a USB converter with a NAD M51? Thanks for reading, all answers are considered helpful.
