Since it actually is a new subject I'd like to investigate, also a new thread!
after building the DAC 2496 (AK4396) DAC KIT With CS8416+AK4393+5532 and enjoying the results of that build, I realized that when feeding the dac with a CD-player I was listening to a 44,1Khz NOS solution. Don't get me wrong: It still sounds wonderfull!
But the urge to extends limits still exists.
Looking on the internet to upsampling solutions I found this dirt-cheap DIY-board (about €10,-):
CS8421 Upsampling Board Suitable For AD1955 DAC Decoder-in Consumer Electronics on Aliexpress.com
Ok, it is not directly meant for the DAC 2496, but it is small and does not have a very complex connection to a DAC-board. Yet I must find out a number of things like:
- how to connect?
- how to configurate
Reading the CS8421 datasheet I found out that the chip is versatile and the proper configuration is set by several 1% resistors "programming" the chips behaviour.
My problem is my lack of knowledge and experience in digital technology, so I'd be grateful for some support, warnings and tips!

I dug up some docs and examples as well as the CS8421 datasheet.
This answers some questions on how to connect the two boards. A simple riser (with resistors) in stead of the 4 resistors connecting the CS8416 and AK4396 will do that trick. That riser also needs connections for gnd and +5V.
What remains a mistery to me is how to configurate the CS8421. Which protocol does the CS8416 receiver send out? I'd really appreciate somebody to help me on that..
Well, in the mean time I'm waiting for the kit to be delivered 😎

HELP!!!!
made some progress understanding the CS8421... but I am not sure if I got it right.
Looking at the schematic of the DA-X0 there is a 24Mhz clock supporting the Master-mode the output of the CS8421 runs in. The inputs run in Slave-mode.
In the MINI2496, both cs8416 and AK4396 run in Slave-mode, 'cous none is supported by a HW clock.
To properly operate the CS8421 in the MINI2496 would require OR a HW clock (CS8421 output in Master) OR the output of the CS8421 has to be switched into Slave-mode. Is that assumption correct?
Has anybody any idea what the implications on the Sound Quality could be running in Slave-mode vs. running in Master-mode and what is the best direction to proceed in ?
