Does the 'Buck' Start with the DAC?


Some members have expressed that the server / streaming front end is less important than the DAC.

I subscribe to the position that "Everything Matters"

As I consider front end choices, I'm trying to gauge if I should be leaning more heavily on a DAC versus a SOURCE (server / streamer).

Feedback and perspective from both camps, or any others, will be helpful. Thank you.

Please Note:  I'm not looking for validation of the position that "only the bits" matter... I accept that some believe this wholeheartedly... and that's okay by me.

The Lumin X1 was discussed a lot in the Best High End DAC thread but I have yet to see a mention of the X1 connected by the fibre optical input. It cost about $200 to buy a network switch with Optical and maybe another $100 to connect this to the X1 from the switch with fibre and the connectors.

It seems to me the goal of dedicated audio streaming servers (computers) is to lower RF noise, using an optimized computer for very low noise and maybe some horsepower for DSP/upsampling options. So I can understand why people praise them so much. However, if the fibre optical input of the X1 is supposed to be the best way to stream data because it eliminates RF noise since this noise cannot travel on fibre optical  wire. Then is a expensive dedicated audio server really needed for a DAC with fibre optical input? Only person that I have seen address this is the owner of the ComuterAudiophile web site on his review of the Lumin X1.

I am not saying that the Lumin X1 is the best sounding DAC but I am wondering if it the best streaming DAC. I am thinking of getting this DAC just for the optical streaming feature so I can eliminate boxes. I would use a cheapo computer, running ROON, somewhere on my network (not necessarily in the same room as the audio system).

The other option I was considering was a optical Rendu from Sonore but that adds another box and the data signal eventually goes back to USB when going into a non-Lumin X1 DAC. However, this option does open up the choice of DACs if the Lumin X1 is not your type of flavour. 

It also seems like most are saying that USB DAC streaming input sounds better in most DACs than RJ45 Ethernet DAC streaming input, for example Mola Mola Tambaqui DAC. I look forward to the day when all (or more) DACs have fibre optical input.
@azwill Thanks for the post. I do appreciate the simplicity of the X1 system. You only have 1 input but that is considered a feature and not a bug by Lumin. The X1 is supposed to be a little darker (or not bright) sounding and that may not work the best with my next speakers so I am looking at others.

Another DAC system that has me intrigued is the AudioByte VOX 3 unit DAC system for $6K (sister company of Rockna). This DAC system has an RJ45 Ethernet input in the HUB unit and that unit is not released yet (likely July 2020). They do some jitter and other cleanup in the HUB. The 3 unit configuration sounds complicated but you only need 1 power cable to power all 3 units.

I needed a new DAC ASAP for headphones (also to serve as a backup) so bought the Benchmark DAC3B a few days ago. I should get it tomorrow. I will use a microRendu to stream to it. So I am now building up a DAC stable too.
