Hi all,
we all know the Polysix is pretty noisy (some units more than others), even more so with the Kiwisix board. While my line output seems acceptable now, the headphones output is still very noisy. I've done all the calibrations in the KLM-368 and soldered ground wires from the analog outputs to join the digital grounding wires. It has improved things but I just can't seem to match the lower noise of the main output. Does anyone have more suggestions? Thanks in advance.
