Thanks!M1 should be able to run DSD256x48. For Spring 3 you should adjust DAC bits to 20 and you should check 48k DSD. From output select SDM for DSD and if you want to output PCM, then PCM obv. Then just experiment with different filters and modulators. Default poly-sinc-gauss filter family is very good and ASDM7EC modulators are all great. Just experiment and find what sounds best to you. Some filters are much heavier though and might not run on your M1.
Managed to get DSD256 to work. Changed bits from default to 20. It skips every so often so perhaps a different filter?
