Jussi,

Do you think the M6 Mac mini can handle the following (the M4 Pro did not in my testing):

SDM Integrator: FIR2
SDM Conversion: XFi
48K DSD: Checked
DAC Bits: 20
Default Output Mode: SDM (DSD)
SDM Defaults:
1x = poly-sinc-gauss-xla
Nx = poly-sinc-gauss-hires-lp
Modulator: ASDM7ECv2
Bit rate: 48K x 512
Multicore DSP: Greyed
Adaptive output rate: Checked

I also hope that it can do this with DAC Correction enabled.

I know many DACs don’t support 48K DSD so that is not required but DSD512 is what I am curious about. The M1 Mac mini can handle the above but only at DSD256…

I don’t have an M6 to test with yet… So it is rather difficult to estimate what it can do.

But I would recommend using the newer generation modulators, as their code has better optimizations and thus consume less CPU power for better quality. I would recommend to try out ASDM7EC-fast, which is the current default modulator.

My base model Mac Mini M4 can do DSD512 with default settings and without DAC correction.

I will try that.

How much extra processing does DAC correction require?

It depends on the particular correction and the hardware running it, etc. It can be something like 1/3rd to double.
