Too expensive mod compared to the DAC performance, unless there are some great and cheap good analog stages. May 30, at I will post some pictures of the board.
No, create an account now. The original parts are: Unfortunately, I can not find the schema.

Sometimes I can hear noise when the player is searching for a track, but the increase in sound quality is worth it. May 29, at 5: Then I took the output straight off the opamp, thru two huge solen caps, straight to the output jacks, effectively bypassing the stock caps, resistors, and muting transistors.
Post 3 of It would be pretty simple to increase bias some so as to drop the input impedance further. Which parts would improve quality? The ones closest to the opamps look like they are the muting transistors. Also, the Pass D1 stage is another one to look at.

I would definitely recommend getting a schematic if possible before just shotgunning parts out. I would like to try better transistors. I performed a similar mod on a Sony DVD player. Post 15 of Colin cetoole looked the design over and saw some things he didn’t like. Are there some transistors replacement databases on the web?
If you can etch your own board, or use protoboard, you could build some of the stages pretty easily. Post 13 of There are improved variations on this, as it was really just posted to get people thinking, but this is probably the simplest it will get while still offering good performance. Can somebody give me a hand?
