DAC kit question

HI,

I have 2 of these and one is still not working after more than a year , but the seller is helpfull.

If I were you I would look at digikey, also some ebay sellers have nice custom clocks you can implement to the dac.

I currently have 4 boards of experimental i/v stages because the weak point of this dac is the opamp output stage which is the same design as 90's cd players , and it is not a sastifying one ...
 
Is it working ?, I noticed substantially more bass on the tda IC from the kit, the one that looks fake, the R1 that I bought on eBay has lot less bass but is more detailed.

Low Jitter clock to upgrade Cd player Usb to spdif dac - eBay (item 220476467930 end time Nov-29-10 06:51:53 PST)

I put a good quality oscillator from the same vendor. ,

Also for your information I am very proud of the regulators (ska miniregs + dexa ) and the custom input transformer. I messed the job with the two regulators for the opamps so I temporally use the LM317 ,anyways this opamp stage is soon bypassed with discrete transistors. You noticed the stack of capacitors (4) in green, its because I didnt had the right value of .22,
