Weakest digital link: DAC - Streamer - Server?


I am curious WHICH of the three is MOST important in digital playback? DAC, Streamer, or Server? I assume DAC is #1, but what about server/streamer?

 

Specifically, I have a Synology NAS which I can host ALL my music on, then using a good streamer play off it via Roon/Upnp, PLUS my streaming services.  Does it make sense to use a SEPARATE server JUST for my music? 

Like is there going to be MUCH difference between these setups?!

1. NAS (music server) --> Good Streamer (ethernet, Roon) --> DAC

2. Dedicated Music Server --> Same streamer (ethernet, Roon) --> DAC

3. Dedicated Music Server with streamer (digital out) --> DAC

 

I understand for SURE, if one connects a NAS USB out to streamer/DAC it will sound WORSE than dedicated music server with low noise components, BUT if I am sending the music over ethernet to a good streamer, WHY would a music server make ANY difference? The streamer would essentially take the same files off my NAS, as if would from Tidal and play in the same fashion... no?! 

WHAT am I missing?!

 

PS. I can also upgrade the NAS with linear PSU to lower noise, but once again, sending audio through ethernet shouldn't matter.

The DAC is the roadblock - not the transport/streamer. Want better sound? Get a better DAC! Lots of choices available! I say this because transports and streamers have been essentially bit-perfect for quite awhile. Whether the source is hard drive, SSD or optical CD what comes out in bits is what went in. Digital data storage is not a problem! Unlike analog digital allows unlimited copies to be made, each identical and not dependent upon the storage material.

Within a DAC the output stage is the final arbiter of sound quality. The chip type and its implementation is secondary. Careful design choices of chips and output devices (transistors, ICs, tubes) can allow production of excellent sounding DACs at low cost! One need not spend four-figures to buy an excellent DAC.
