This WIKI is for those who have suggestions on recommended parts for Pedja Rogic's TDA1541A DAC.

The main thread is here: https://www.diyaudio.com/forums/showthread.php?s=&threadid=29604&perpage=40&pagenumber=1

If you have any favourite brands that you wish to share, please edit the original parts list below. Hopefully this will take some of the guesswork out of part selection for the less experienced builders out there.

Cheers

Assuming this page is for US suppliers I've put some information together for UK/EU suppliers here PedjaDACeu
