*SOLD""
This is a I2S to simultaneous mode TDA1541 dac board designed by Miro. I have built a few boards, and i am only keeping one board for my own system. This is the second spare board i am trying to sell. It is built with care and high quality parts, tested to work with stability. Your own PSU and i2s source is required to complete this DAC for it to sing.
The 14 decoupling caps for the TDA1541 chip are high quality RIFA MKP, with values as per Miro's recommended BOM. Decoupling caps for the psu are KEMET MKP, and electrolytics are mainly Nichicon FG for the DAC section and ELNA Cerafine for the op amp IV. Resistors used are Vishay, including the zero ohm jumpers and the IV resistors is DALE RN55. Logic chips are decoupled with high quality Kemet SMD x7r capacitors.
This dac is designed by Miro and more info can be found here :

Miro also designed the PSU for this dac (not included in this sale):

Please study the power supply requirement carefully if you intend to use your own psu design.
Important things to note :
1. If you intend to have no capacitor at the output, it is advisable to have a dc protection board as explained in the post:
https://www.diyaudio.com/community/...s-input-nos-r-2r.354078/page-285#post-7187720
2. Tested with JLSounds i2s card, i have trimmed the TDA1541 offsets to be null and very stable. Any changes to the board, including inserting different op amp and different TDA1541 chip will require adjustments again. Please do check and do necessary adjustments by following the instructions by Miro. You will need to explore this on your own, with your i2s source connected.
3. All components, including the TDA1541A chip are new, which is only used for the testing of this DAC. The exception is the pair of output op amp AD797, which are old and used by me for previous projects.
Of course, the board has been tested and playing well. Price for the board is 220USD, including shipping worldwide registered. And as usual i will buy coffee for Miro.

I am interested. I am a bit of NOOB to all this so forgive the questions. I am currently using a Topping D50s. Would this be significantly better? How big of a job is the PSU?
@theaddies , I do not own the Topping D50s. 'Better' is too subjective and in what way? Topping has remote control and Bluetooth connectivity ...so it can be better in these ways. NOS dac are well liked by many here for their personal listening preference due to their sonic quality. Maybe you can research the topic of TDA1541 DAC in this forum and draw some conclusion.
The PSU can be made very simple, nothing sophisticated , just like the link i put in my post.
