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.)

I have the Topping D90.  It has very nice parts in it.  I would say very neutral and transparent.  I can only comment on the comparison to the Bluesound Node 2i DAC.  The Denafrips Pontus gets very good reviews and is R2R.  $1694
your 2 channel will be fine.  Can it be better?  Of course it can.  It can always be better, but at what cost?  That's when you figure out what to do with 2 channel.  Try it the way you are doing and then we can talk, lol.  :).

It’s difficult to understand what you are targeting when your OP says “high end digital” (what does this mean to you?) and it appears you have not stated a budget.  
Generally speaking, digital audio playback requires a server(where music files stored)> streamer(transportation/delivery of music files) > DAC (translates files to an audio signal).  If you want to spin SACD/CDs, you’ll also need a transport.

A CD player has both a transport and DAC built in.  In high-end audio, for best performance it is generally better to separate the functions to better isolate components from vibrations and electrical noise but costs more in casework and additional cables.  Also, usually a DAC+transport is significantly sonically better than a CD player unless you spend considerable $ for a higher quality player.  For greater flexibility (upgrades), better performance, and lower cost, most high-end digital systems have a stand alone DAC vs a CD player.

Well I was not thinking much of budget, but less than 10k.


But high-end to me would be something that sounds good and does not sound like it is obviously coming from a CD player.

Since the AVR has the Roon End-Point and DAC built in, I will try that first. Plus it has some built in room correction, so maybe that will help sound in terms of bass and EQ, without destroying imaging?
I’ll see I guess.
