Hi all, I’m very sorry if this has been asked earlier.
I recently bought (but sent back) a GeekPI nvdac nvme audio-hat/m.2 card because i got a lot of static noise from it (assuming that the interference was due to lack of shielding).
I’m now looking at the raspiaudi variant of the same concept and i wonder if it also is plagued by the same issues (or if it is actually working fine)?
Any IRL users who can comment on this?

On our Pi Audio Drive, we designed a 4-layer PCB with careful routing: differential pairs for the drive are isolated and kept far from the audio tracks. The result is zero noise on the audio, even during high-speed data transfers.
The Pi Audio Drive also features two powering options: it can be powered directly through the Raspberry Pi, or via the shield using the USB-C Power Delivery (PD) standard with a 12V profile. This further helps reduce audio noise.
In addition, the Pi Audio Drive includes audio inputs, onboard microphones, and speakers, making it ideal for video calls without extra hardware or for voice assistant applications.
Thank you for feeding back this info, much appreciated 
My use-case here is to build an instrument based very clean audio and so i was a bit careful and went with your Audio+V3 instead which will still be perfect for its use.
Not my last project (hopefully) and so i will certainly investigate the Audio Drive as well.
Thx 
I am also interested in the Pi Audio Drive, can I easily connect a Primo EM272 mic to it, what about noise produced by the Pi 5, the Pi Audio Drive or the power supply? Thank you.
Hello note that there are already 2 condenser microphone onboard but sure it might not be good as the one you’re mentioning. It will work well it your 
uses 2 wires.
The 2 mono microphones inputs are fully differential this with very low noise.
