If anyone wondered what the equivalent of valves for a solid state DAC is:
Welcome to interface rolling. :)
But I agree.
Next imo: Power solutions.
My DIY power cord with RFI/EMI POWER LINE FILTER.
Still under construction waiting for better enclosure to arrive but is fully functional and working just as I expected. It is not my first passive filter I've made I have made much more in my past and some of them still going well in my friends audio system after all years, but that was when I worked for electronic repair company had access to parts, equipment etc This time I went shortcuts and used finished product from CORCOM Q Series filters developed specifically for switching power supplies (typically switching at 200kHz to 1MHz) and is designed to filter the power line to control conducted emissions all the way down to 10 kHz. Similar characteristic filters i used in past to build some power line filters and works best with the digital sources. Very low leakage current even at max load 5A/250V there is no degradation of performance due to the large peak currents drawn but that was the reason to use it over-sized couple of time.
