*****SOLD*****
This is a I2S to simultaneous mode TDA1541 dac board designed by Miro. I have built two sets with two TDA1541 chips that i bought.
The 14 decoupling caps for the TDA1541 chip are CDE 0.1uf orange drops. Decoupling caps for the psu are Wima mks, and electrolytics are mainly Elna Silmic II. Resistors used consist of TAMA electric , Vishay and the IV resistors is non-inductive, non-magnetic, copper leaded Nikkohm. Logic chips are decoupled with high quality Kemet SMD x7r capacitors. The electrolytic caps may have some minor burn marks on the plastic sleeves due to my own carelessness during various desoldering to test different caps for sound. But i assure you that they are really minor.
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.
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:

2. Since i do not have the intention to add a DC protection board, i simply add output caps at the output and i did not further explore the dc offset trimming. But please be aware that DC will be present in the absence of the input signal as mentioned in the thread.
Please follow the instructions by Miro on the trimming of the offsets. You will need to explore this on your own, with your i2s source connected.
3. The only item not provided on this board is the two single Op amp for IV. The rest of the components are completely populated, including the new TDA1541A chip, which is only used for the testing of this DAC.
Of course, the board has been tested and playing well. Price for the board is 185USD, including shipping worldwide registered and paypal fees absorbed by me. And as usual i will buy coffee for Miro.
