Use the CPLD board from China.

My plan is to use that board. Actually I am looking for the DAC board itself. My goal is a dual 1541 board where each DAC operates in balanced mode (L+/L-, R+/R-), accepts simultaneous offset binary, and perhaps there are onboard shunt regulators. OK, maybe I will design it, or just link the components together on a veroboard.

Thanks! Don’t I know it!

I’ll check out the boards. I have built Pedja’s DACs (an Aya is still in my system doing sterling service today), and was looking to see what else there was out there with two chips. John’s suggestions in this thread really piqued my interest.

Not with proper reclocking and PSU filtering.

Building the ultimate NOS DAC using TDA1541A
Hello - I am in the very preliminary stages of a TDA 1541A design. I have read good things on Sowter 1465 I/V interface transformers. Anyone has experience using them? They are meant to generate a line-level output with a high-value resistor across the secondary, however seems one could use a lower value resistor and present the TDA 1541A with a smaller load at the cost of output voltage and add a gain stage to the secondary, I'm curious if anyone has experimented with both configurations, thank you

Many tested and man came back to active I/V . There is no real evidence this (and other) transformer is the best at this job. This is not it's bad, it's just there is better for this chip.



Seing your avatar, I would try a tube for the I/V task (Thorsten Loesch) .
