I recently received a sd card player that plays wav files. It sounds incredible. It can play 32/384 files if you can find them. I have been listening to 16/44 files for the most part. This along with the the Relaixed2 preamp has brought my system to a whole new level.
+1 Very kewl.So only wav files,no flac?
From what I have read on the diy audio thread, playing from wav is the most direct way these two computer guys know to get the best sound. It does sound much better than the shigaclone cdp. It sounds like sacd even though I am playing 16/44 files from regular cds. No remote yet but there is talk of an arduino add-on for remote control. Rich may have me getting into the arduino world yet. Thoughts of integrating the TPA Buffalo and the SDTrans384 into the case I already built for the Buffalo. It never ends!
I knew there would be I2C control with LCD in your future!:cheesygrin:

If you go Arduino, look at what Corpius offers as a shield that plugs on to an Arduino UNO.
He also designed a controller or Arduino clone.
My afil with him is internet forum friend and satisfied customer as I bought two of his early shields and currently use one in my DAC. The shield minimizes wiring and has additional I2C outputs for serial control of other devices along with IR input for remote and backlight control for LCD screens. It has a level converter to drop the I2C voltage to the 3.3v the BIII requires. He supplies his own version of the code that HiFiDuino started.
The only other add on I would suggest is the Sparkfun I2C LCD extra IO. That reduces wires to the LCD through I2C control of the display.
The best display (although no backlight control) is the OLED. Much better off axis view than LCD, crisper, clearer. You can add code to shut display off in time of your choosing. IIRC it requires direct power due to exceeding Arduino mA output capability. Still 3v or 5v power. Color choices are blue, yellow and green. Pinout may be same as LED, have to check if I2C extra LCD module would work with it.
I replaced the ps with a ti tps 7s4700 eval board ldo regulator. Sounds even better. Can't have the computer on any more. Too much noise. Listening to Captain Beefheart. Sounds better than I can imagine.
Case is done
Finally made a case for the sdtrans384. Jataba and perf steel. No buttons for play ect , remote only for now. If I get motivated I will make the 4 buttons but not a priority. It still sounds better through the I2S compared to the Bnc.
Didnt load the pics fast enough.
Really nice looking unit.
