| Hacking a cheap-0 USB DAC. (Or, helping a cheapass get better sound.) - Click HERE for Original Thread |

I've been using a headphone jack to RCA adapter with my laptop, and it worked okay. However, now that I've got my Denon CD player ($4.50 at St. Vinny's) up and running, everything sounds much better.
However, endlessly switching out the CD's is a pain, and my taste for obscure Ska means that I can't get my music in any other format than Mp3 without buying CD's from a coffeeshop in the Czech Republic.
So, what's a cheapass to do?
Hack!
USB soundcards now sell for under 10$. So, why not use one as a starting point for a better-quality DAC?
DAC number one
DAC number two
DAC number 3 - with seperate S/PDIF output!
Number Four- Made by Behringer and also with S/PDIF
Although none of these are top-quality items, any of them may have potential as an inexpensive USB DAC option. Perhaps the Behringer, with some improved power filtering (got capacitors?) might make a nice S/PDIF source, and if the op-amps are replaced, many USB soundcards might be made to sound pretty good.
Thoughts? |

You need to search for a device with say PCM2707 in it. Then you could tap I2S from it feed it to a good&cheap DAC (say non-os stacked TDA1543) and add a better supply/clock.
Search on google for info on USB devices and let us know :)
