Try Marcel's RTZ discrete FIRDAC dac with Cestrian's clock and reclocker board, I2SoverUSB, PCM2DSD, and mutually isolated power supplies (with hum breaker circuit). Add Iancanada SC Pure clocks to that and you will get pretty close to the limit. Kick it up another notch with Acko clocks if budget allows. We are still working on a more or less final recommended output stage. There are some existing designs to try out in the meantime.
As far is coaxial SPDIF sounding better than optical, it depends. In some cases SPDIF will be lower jitter, but other problems could dominate over transport jitter. Problems with SPDIF and TOSLINK can be largely but not completely solved with a FIFO buffer. Why do you think people keep buying Iancanda FIFO_Pi boards and accessories? They plug together so no SMD soldering and while IMHO they don't sound as good as what I would recommend, the FIFO board could still be incorporated into a system I could recommend.

it looked interesting, I read the original thesis that was published in Germany.
they built something with tubes, and I read the RTZ on the forum a little.
It didn't convinced me that it could be an advantage over akm4396 or pcm58 which I am about to try.
I am doing some tests to see if what I have is adequate I will record different dac and substract and add to original audio.
I need to reduce the volume to 8% (of the digital bits) because the ADC limitation of voltage input. But it will tell me once and for all if it works!
Ideally I want a balanced dac output to feed my SS amp (opamp input in balance mode).

Right now the only thing that would benefit my system I can think of is 12sl7gt smoked versions, lower odd harmonics.
and some good KT120 outputs! I just need to take the time to build it as well as new loudspeakers.
I will see how the pcm58 projects goes and then maybe if its a failure I will contemplate this dac.

The computer makes some electromagnetic noises which are catched by the rca wires to amplifier.
The toslink has a slight noise floor higher than usb, but it does not carry any noises from the computer
The emi filters are efficient for protecting the power supply side of amps, toslink is probably the best way to connect computers , but still they generate a lot of frequencies which some amps are more succeptible of catching through interconnects
