After reviewing the schematic for sometime, I decided to modify this DAC to remove the transistors from the headphone amp and strapped the Op-Amp as 1:1 buffer. Then, remove the input coupling capacitors and take to buffer output to the RCA jack.
This would provide better buffering from the DAC to the line amplifier. Also, I could use the volume and the DAC can be connected directly to any power amplifiers.
After this mod, the sound from the CD players sound more brighter that I would expect.
Now I can enjoy my CD collections all over again.
I am wondering how to squeeze more juice from this DAC, any ideas??
