Do you mean an Aliexpress/EBay type thing or an evaluation board from a semiconductor manufacturer ?
Uwe Beis, offered some really excellent modules.
AD24QS is his ADC offer specifically for audio, both with balanced or single ended inputs. Sampling rate up to 192kHz. And with through-hole components!
But...they are sold out due to parts shortage.
He's planning a successor actually: AD2-QC.
Unfortunately, it seems to be an all-SMD design, so not as much DIY-friendly as his previous offer.
To be honest, i'd love to see more 'audio oriented' ADC designs on offer.
So you'd be able to pair it with your extravagant, vintage analog setup.
Say, your awesome Garrard turntable, with its high-output Shure M7D (or similar) and digitize your precious records, in the spirit of preserving that analog 'magic' as much as possible!
And in my humble opinion, an all-SMD design may fall short in accomplishing that (SMD-lovers please don't be offended!)..
Still, there are absolutely zero offers (DIY or otherwise) with that in mind. At least, as far as i know.
So, it'd be great if there was a DIY project with only the bare minimum (essential) SMD chipsets presoldered and the rest of the build using through-hole components!🙏
Giving audio-freaks the available option of tweaking the sound, using the appropriate components of choice.
For example, choosing your own coupling/bypass capacitors and socketed DIP8 opamps. Or even the types of resistors, in certain critical positions.
I know, I sound crazy...
Only basic requirements would be:
-Sufficient bit depth (16 or 24-bit) and sampling rate (96 or 192kHz).
-High input overload margin (some MM cart designs are high nominal output i.e. 10mV).
-Option for using a linear power supply.
-High input impedance (250kOhm or higher), to accomodate for certain high output impedance tube RIAA designs.
-Sufficient space for larger components (for the PIO cap lovers out there).

All the above are just my own crazy 'vision'.
If anyone else has similarly crazy ideas, please feel free to add them.
Regards,
Nikos.

It's been a long time since I bought the ADC kit there.
I don't remember exactly how much it cost.
But I can check... Somewhere between 100...200€ I think.

Ok I cant afford it ATM,by the way I surfed on a page that offereras evolution boards so I wrote that I wanted to try one ESS9822pro.
Hope they dont turn down my made up company.

I have one of those kits as well from mr. Beis.
As i mentioned before, It was (and essentially still is), the only serious DIY offer for an audio-oriented ADC module.
And one which could satisfy audio enthusiasts.

By the way, I'll have my own AD24QS returned pretty soon!
Will try to create a few sample recordings from vinyl.
And even upload them here for comparison, for anyone interested.
Recorded with the AD24QS and with a Behringer UMC204HD.
The latter has the electrolytic capacitors at input, bypassed with film caps.
Will probably do the same for the AD24QS.

Another member also seems to have few of his ADC boards available here: https://nihtila.com/2020/07/05/adc-ak5572-v1-2/

OMG, $1200 just for the PCBA without USB and power supply looks quite affordable, right? 🙄
