On my base M4 Mac mini, super, v2 and v3 works at x256 48K with DAC correction. I find with at x256 I don’t have any issues with most filters I tried.
x512 I need to do some budgeting as it is pushing he limits of the M4 Base Mac mini.

I was just going to reply that I will test this tomorrow but it looks like Brian beat me to it!

I have to, as you say, do some budgeting with a Mac Studio M1 Max with 512, actually it a lot of budgeting, but most work with 256.
This is without dac correction though.
May have to wait out a bit on an M4 upgrade.
Thanks for the feedback. 
I now have a DAC that has corrections available, i am able to get 256 48k with corrections enabled using ASDM7 (EC, ul, light, fast, and super) using a good amount of filters. Some of the longer ones as expected do not work. The v2 & v3 are problematic.
I’m using a M1 Studio Max.
Now I wonder how much faster the M4 Studio Max is compared to the M4 Mini Pro.
I’m asking the question here, but I currently have a Mini M2 with HQP5 Desktop and a Holo Cyan 2 + Naa on a NUC I5… no problem with SDM256 and the new ASDM7 filters.
*Does switching to an M4 instead of the M2 make any real difference apart from being able to switch to SDM512?
I thought it was better to opt for the 256 with the Cyan 2.
Another question: wouldn’t opting for a NUC I5 or I7 with a Linux distribution be better than an M4?
Jussi,
Would you mind sharing your base Mac Mini M4 settings when using ASDM7EC-super 512+fs for DSD512? It doesn’t make sense to me that I get stuttering on my Mac Mini M4 Pro so I am wondering if have something set incorrectly.
Here are my settings:
- Default Mode - SDM
- 48k DSD - checked
- Adaptive rate - checked
- Fixed volume - checked
- Oversampling 1x - poly-sinc-gauss-long
- Oversampling Nx - poly-since-gauss-hires-lp
- Bit Rate - 48kx512
- Multicore DSP - grayed
- Blocks per cycle - Default
- DAC Correction - enabled
Thanks - Nick
I’m thinking if you’re happy with the filters you’re getting @ 256 with the M2, the M4 isn’t going to help you much. If you’re trying to get to 512 it may help. Much like your M2 mini, the M1 Studio max I have is good with most things @ 256 with DAC correction enabled. With 512 it’s very limited on filter and modulator choices.
I’ve curbed the urge to get a M4 Studio, before you know it the M5 will be here. 
I would think your M2 will be better than a NUC. NUCs are mobile Intel CPU’s, I don’t believe their single core score is better than the M2, let alone an M4.
I’d opt for a desktop chip with a good GPU and Linux before a NUC. If you’re thinking about a NUC because of size or power consumption, you’ll probably better off with what you already have.
With Apple Silicon, I would try graying the Adaptive rate and the Multicore DSP.
Thank you for the suggestions. I made a couple of mistakes on my settings. I have Multicore DSP grayed and Blocks per Cycle set to Default. I will gray Adaptive Rate tomorrow and test it out.
I don’t think I’ve got such working. Looking at my earlier screenshots, DSD512 with ASDM7EC-fast and DAC correction, or DSD256 with ASDM7EC-super and DAC correction.
Your overall settings seem otherwise similar to mine.
No dice! Thankfully ASDM7EC-fast 512+fs works with no stuttering and sounds pretty good.
