Post 9 of For my DVD player, it wasn’t worth the money to rebuild the entire analog output stage. Also, the Pass D1 stage is another one to look at. Post 8 of Headphone Reviews and Discussion – Head-Fi. The PCB set is 18 Euro, and he can supply parts as well. Yes, my password is: Post 14 of What DAC is in here?

Post 11 of I seem to remember Garbz posted pictures of dataxheet Pass D1 variant on here; I forget if he had board images though. May 11, at 2: Too expensive mod compared to the DAC performance, unless there are some great and cheap good analog stages.

Thanks for the tips.

Need help for transistors upgrade. Current or voltage output? Sometimes I can hear noise when the player is searching for a track, but the increase in sound quality is worth it.

May 28, at 6: Share This Page Tweet. I would like to try better transistors.

May 29, at 6: Colin cetoole looked the design over and saw some things he didn’t like. Post 13 of May 29, at 5: I really would suggest leaving the transistors alone, especially since you dont have any idea what they do in this circuit.

The original parts are: What I did was to change out the opamp and replaced it with an OPA It would be pretty simple to increase bias some so as to drop the input impedance further. No, create an account now.

I will post some pictures of the board. Some of the variations get quite complex; the one I am working on for my DAC projects currently uses something like 62 parts per single ended channel, so would be in the range of parts for differential stereo.

To your original question: Do you already have an account? Your username or email address: It would be much more worthwhile to replace the whole output stage, preferably with a discrete solution.
