Well, we bought two of them and both has the same fatal for sound error: instead of -12V analog supply for PCM58 there's only -5V. It still works but completely out of parameters. You can easily check your KIT for this BAG - just compare resistors value near 3xLM317 stabilizers and if they all the same ( blue-white-black-black = 690 oHm and red-red-black-black= 220 ohm) then you are in
! Or just check U on pins 9 or 20 of PCM58. Please, note that LM317 is POSITIVE stabilizer but in spite of this it is in NEGATIVE configuration (on attached picture there's stabiliser on right side of board just near the 3300uF Kenwood (Elna) capacitor). All you have to do is to change resistores value: 690 ohm on 1,3 kOm and 220 ohm on 150 ohm (1%) and you will be suprised
!
Also this DAC has no deemphases filter witch means that some old CD's will reproduce overtuned high frequency noise. I will make passive filter later and let you know.
