How to get into high end digital? (Feeding a DAC)

I am looking primarily at the Schitt Yggdrasil or the Topping D90.
  • How does one feed those?
  • I am assuming any sort of CD transport would output the bit stream?
  • or… they get saved to file and played from some media player into the DACs.

Some example of what is commonly done would be great.

The system currently consists of:
  • TT —> Audio Research PH2
  • An old Nakamichi 5 disk CD player
  • TV
  • Audible Illusions line stage (New tunes on the way, but it still sound OK to me with the old tube in it)
  • Prima Luna (with GoldenLion and TS KT-120 one the way… and I might I’ll get the VTL mono blocks 100w/ch serviced)
  • Vandy 2C and Vandy sub

I also have a Home Theatre pre, which is Roon capable, on the way… So that maybe does some of this for me as well? 

But to be totally honest, the digital side is a bit of mystery to me.
I have always thought we plug in a CD player and the signal comes out. (Maybe with some nuance in DACs, clock jitter, and filtering to separate the higher end from the lower end products.)

Thanks @buddyboy1 that sounds similar to the Yggdrasil with the R2R.
@jasonbourne52 what is the impedance of coax? I would think if it is 50 or 75 ohms, then the VSWR would be low?

If I did the maths right then the speed-o-light/44.1kS/sec is ~6800 meters between samples.
@aubreybobb I appreciate you taking the time to write it up, but using 3 switches seems like it is like almost like a holy Trinity. And no one has been able to tell me how feet, power cords, and magnetic platters can affect bits… so I am unsure whether this is measurable?

Pure digital is totally accurate but not everyone's cup of tea. We are influenced by our past.
If I can measure the output and compare it to the input and see that it more true than comparing that stream to the Vinyl, then I can convince myself.
I may not like it, but I am pretty much a “by the numbers fellow”.
And I would then likely try and understand why I like the worse one better.
I know that is the case comparing my VTLs to the Haus-Boss’s NAD amp. The VTLS have a huge amount of IMD. The NAD was more faithful to the input.

@henry53: parts costs to build DACs are are in the hundreds at most! Four-figure  and up DACs are high-profit items! Don't forget these companies are into it to make money!

A $500 Cambridge CXC transport + a $300 Khadas DAC is a formidable combination!

You sound stressed.  Relax.  Digital is easy.  Get a decent CDP or transport, a cable that is at least one step above Radio Shack, plug into a DAC or else just use the DAC in the CDP, sit back and enjoy music.  Add a streamer later if you want, or else just use a computer for that (presumably you own one of those already).
  It would help if you told what your budget is.  You are all over the place.  I don’t want to recommend an $80K digital set up if your budget is 8 cents
