So I use a DAC that has its D to A converter chip and circuit optimized for DSD 256. This means the computer and Audirvana have to up convert to DSD 256 in the program. I recently purchased a new Mac Mini wih M1 CPU as it is reported to be a very good machine. I can perform DSD 128 conversion, but when I select DSD 256 i get white static and a high pitched squeal overlaid over the music. When watching the utility that shows CPU usage it pegs at 243% and stays there for as long as signal is being fed. At DSD 128 it jumps to 200% at the beginning of the track and stays there for about 5 seconds and then drops to 20%. When using PCM 352.8 kHz I am at 20% CPU usage.
Is there any reason why the new Mac Mini M1 cannot do DSD 256 conversion? Everything from bench test numbers show it should be capable. Is there anything within Audirvana that is incompatible or limiting for what I am needing to do?
Thanks for any info you can pass along.
