If you need hi-fi you must buy external DAC anyway. Motherboard is crossroad of EMI and even if manufacturers do their best the same chip will always work better in external metal case than on the mainboard. Aorus Master B650E has ESS chip which is IMO wasting.
Does exist some double-blind study proving that people are able to distinguish or perceive such a high refresh rates or is it a video*) snake oil?
*) An analogy to audio snake oil where various cables or devices for hundred or thousand dollars do literally nothing.
I got L30/E30 (both the first version) with one AK4493 (version II has pair) and works well (under Linux). L30 is set to the lowest gain since it has really enough power.
I would buy them again. IMO selection of good headphones is an alchemy while selection of good DAC/HedAmp is easy these days.

You can of course buy a no-name grill for ~2EUR but that's another story.
Note that TBW is almost impossible to test. We have to believe to manufacturer. We have detailed reviews here on TPU, synthetic benchmarks, real world benchmarks and even pictures from thermal camera. But do the drives have really declared TBW? That's unanswered.
It is mentioned, those are dramless SSDs, focused on low power consumtion (for laptops?)
And IMO, their in-house controllers are - well not bad but definitely not the best.
I also prefer AMD because of their open-source Linux drivers. Therefore, I was surprised that nVidia opened the drivers too: https://www.phoronix.com/review/nvidia-open-kernel in May.
I somehow missed this info, I don't know if it was published here, I know it week or two.
I hope they'll be available in Europe. Hynix P31 Gold was listed on Amazon.de but stated "Item cannot be delivered to your adress (CZ)". P41 Platinum is available on Amazon.com but not on Amazon.de.
In fact, there are just three chipsets A, B and X. The E means that mainboard has a few layers of PCB more and is capable to run at PCIe 5.0 speeds. Motherboards without E are expensive. Motherboards with E are very expensive.
Founders Edition for $1600 and other AiB cards for $1700 for literally 1% higher performance. Here it is $2000 for 2-3% from ASUS. It seems that each percent more is for $100 :).
nVidia doesn't give much space for AiB for overclocking cards. No wonder EVGA left that bussiness.
