Ah, these SD card players are turning out not to be reliable at reading SD cards.
Unless we can find a reason or explanation for this & how to avoid it, it kinda topples the whole 'project'

So has anybody sorted out how to interface the ESP86 with the control buttons of the SD card?

Great, Randy, keep it up. Sorry I can't put the work into this that's needed - too busy at the moment with other things - hope by next week to have freed up my time.

I could not help myself. Bought the player/dac linked above and look forward to comparing it to my SDTrans/Soekris setup and doing some mods. Has anybody here other than Rick gone the SDTrans route? My impressions are similar to what he wrote earlier on this thread. I prefer my vinyl setup. Have no...

I do not think you will regret it one bit Fran, it is a great piece of hardware on its own with a good screen, buttons, front panel and case for the price. The board must have updated firmware to take 64Gb cards and it should be a good base for modding as the unit is big with plenty of room inside ...

IanCanada on that DIYAudio thread seems to like the Ultracaps. From memory he has favoured LiFePO4 batteries in the past so maybe his will be the best comparison of one Vs another? I presume he is using Vregs on Ultracaps output so I can't see how they could sound better than LiFePO4 without caps? ...

In my experience this configuration seems to eliminate CM noise but I'm not sure of the mechanism by which it is doing this. I guess it's a case of seeing the system wide picture of the current...
