I don’t know, but I don’t encounter such issues with Red and NAA OS, and I never switch input away from USB.
You seem to have a hardware issue somewhere. Either related to he USB cable or the USB interface module.
@jussi_laako Windows just did a security update and ever since I’m getting noticable clicks on anything above DSD 256. (Less noticeable below DSD 256 but still there) I’ve uninstalled and reinstalled everything. After I rolled back the update everything is back to normal. Is there a patch or something available?
does it sound like the static I describe with anything above PCM 16 fs or DSD 256 I describe ?
wonder if the issue did not come back after a OS update (Mac though)
Yessir it’s clicky static

Thank you Jussi, we can rule out the USB cable, tested 4 including the new Supra, certified.
I was about to contact Magna to whom I purchased the Red and May with suspicion of Holo USB interface issue but now curious about @Darthspader
Nothing obvious in the update description:
Most important generally with Windows is to have the Defender disabled. As it has tendency attempting to scan the audio content streaming for “viruses” or whatever. And obviously that is a futile exercise, it will just choke the machine and the connection, as the amount of data it is trying to deal with is naturally ever growing.
So using a third party security software is recommended. I have tested that F-Secure and Avast at least work without any issues. Both offer free trial period as well. F-Secure is more straightforward to deal with, Avast needs some setting adjustments, otherwise it will aggressively block all network activity.
I reinstalled the security update and the clicks came back so I added roon, HQPlayer and my music library as exclusions in Windows defender… and voila fixed.
My issue seems to have been windows defender, not sure if that will help you for MAC.

Jussi, did you upgrade your RED with CM5 ? If you did, does it boot from microsd okay ?
No, I have not seen a reason to do it. I don’t really want to mess with the Red hardware…
Hello, I am a new HQP tester, but I have a problem to set the filter that everyone writes about, namely AHM7EC8B, my equipment does not want to play on it, the last one on which the play is ASDM7EC super 512 fs. Can someone explain to me how to set the settings for this filter to play? My hardware is Mac mini m4 16gb ram → HoloAudio Cyan2 all connected by usb cable . Thanks for help
AHMxEC8B modulators require minimum DSD1024 output rate.
Since on macOS you need to use DoP, you cannot reach DSD1024 due to the associated 50% transfer overhead. The way to work around this limitation is to use a Linux-based NAA (network endpoint) between Mac and the DAC. One of the most cost effective ways to do it, is to use Raspberry Pi4 with my NAA OS. It is also pretty much plug-and-play. This way CoreAudio gets bypassed.

OK, I take it all back. I reverted (regressed?) back to DSD256 into the TT2 and, by god, I like it–tech specs be damned!
Despite the PCM conversion (i.e. decimation to 705k) there is something in the authority and slam that still translate while PCM output sounds thinner and weaker. I don’t think its ringing or noise (from poor conversion), I really think its more available information that is being articulated well.
It’s not all rainbows and sunshine as I find myself continuously hunting for the “right” modulator/filter combo. I have found a lot of success with sinc-L, sinc-m(x), and xtr- and gauss-family filters paired with the DSD7 256+fs and AMSDM7 512+fs modulators. Right now sinc-m(x) and closed-form-16m with the DSD7 256+fs is working with the alternative rock I like, e.g. Big Black/Atomizer, Slint/Tweez, PJ Harvey/Dry and Breeders/Pod.
This is me postulating but the Chord dacs (at least the TT2) and the EC modulators don’t play well together, and the music gets altered in subtle ways that can make it fatiguing or just shouty. DSD7 256+fs and AMSDM7 512+fs are usually on point.
I didn’t want to re-open the Chord/HQP discussion and just wanted to share so other Chord users could also emerge from the shadows (haha).
(and maybe I just need to get a NOS/R2R dac that can natively process DSD since I like it so much…)

I am going to double-down on the EQ capability available in HQP.
I will also backtrack on the modulator/filter combo recommendations and say go for the “best” combo available, and bridge any remaining gap with EQ.
For me (still being on HQP 4) that goldilocks combo is AMSDM7EC 512+FS & poly-sinc-gauss-xla. The Gauss family provides the right weight and texture (sorry to use such technical terms) to support a true hifi experience. I previously thought a long filter like XLA would have the shortcomings with transient response, but looking at the HQP guide it hits transients, timbre, and space, i.e. everything.
The issue I’ve run into is falling for the ear candy that filters like closed-form-16m and sinc-L, e.g. the perceived punchiness or space they give. After the initial excitement and once your ear becomes accustomed to the new filter you may, for example, begin to feel the missing texture of the closed-form or softness and lack of precise detail of sinc-L, which to me is a loss of information. EQ is a better place to tinker to get your music where you want it while still providing your DAC the highest quality input.
If you use a Gauss filter and feel like its not punchy enough or its too congested, I would go to EQ first. The filters are so different that you will lose your mind (I have at times) when you are constantly switching.
I don’t love supporting Google but Gemini has been fairly effective at getting Matrix processes for EQ. If you don’t know where this stuff is in HQP just ask AI.
It’s also deeply ironic that we invest thousands of dollars into hifi equipment but the vast majority of music isn’t mastered for us.
