My instinct says that part of the magic of this solution is creating a simple path where the SD Player (running with good clocks and clean power) generates an I2S signal, reclocked with a potato semi FF (at least thats what I do) and you feed that signal though short wires directly into an appropri...

Thanks, Pearse for your update on your SD card player - sounds very interesting

A couple of things about this design - I can't understand how the external clock input could work - there are two on-board clocks which presumably are switched between depending on the samplerate of the audio file being played (which is s good design practise although a good oscillator rather than c...

Good news, Pearse, thanks for doing this Seems like there may well be lots of areas for improvement which bodes well for final sound quality: - in the power sections, bypassing regulators with direct supercap supply - Should be even better sounding with I2S taken directly rather than through HDMI - ...

Thanks, Pearse
If it sounds good it looks like a good hardware base to have a play with & possibly develop another interface for it?

Thanks for the pics, Pearse I thought from the Taobao pics that it was using oscillators (possibly NDK) not crystals? TPS7A4700 are good linear regulators Does the remote show all folders/files when the SD card is inserted into the player or does it continually read info off the SD card & transm...

I think I was using an ESP8266 to send a high signal to mimic the button presses..... Yea, sorry ESP, not EPS as I posted & this is a WiFi board - it looks like that's what they use on the SD player Pearse has? It may be that directly connecting the switch electrical contacts to the ESP, may ha...

Yea, the one Pearse has is likely the best hardware - if we could get a remote control app work like the BlutoothBox app, it would be perfect? So, again my idea would be to copy music library to SD card & the control app would use a mirror of this folder/file structure to navigate through & ...

The SLC cards give quite a good lift in SQ - enough to make me buy one!! Right, I hadn't herad them so this is good to know You are more than welcome to the dead card, I think I measured the push buttons as just sending a high or low TTL signal. Also, Pearse has an annotated diagram of the card wit...

Great, he got it, thanks for heads up - I'm sure he'll post when he is less busy & has some info?
