A) Upgrade hints:
4. Silver Wire of MCK, DATA, BCK, LRCK will be a good result.
// You can compare the result by using IDE cable, Silver cable, and copper cable (LAN cable). Suggest you finish the board early and do this comparision early.
Q: Is it good enough if I use the silver wire (pink colour) attached on the USB module which last time you tested on my PCB board?
// You can consider LAN cable (copper wire) be a power supply cable. The total power consumption is less than 100mA.
No need too thick, pure copper is recommended.
B) Can I use back the USB module which you have assembled and tested on my PCB board last time? because I've used over 2 hours to solder the wire and tailor make the mounding.
// To be fair of another classmate, all of the Diyer should soldering their board by himself.
C) After your recent test:
Playback:
I am usign WMP11, any MP3 song, it show 44.1KHz in the LCD panel of AD1955. No need to set in PC.
Q: Do you think the quality of the MP3 song playback by AD1955 pro better than market $2k sound card?
// If you trust my founding, the performance will not let you disappear.
Suggest you carry your MP3 (put it at USB stick, I don't have CD-ROM). And test it by your ears.
Atleast, the power supply of DAC VS Soundcard. DAC must be better, also, Opamp is better than sounccard la. |
