Sonic differences between servers


Looking to replace my Roon Nucleus.  Have read many of posts regarding the various options; Innuos, Antipodes, SGC, and Salk.  Definitely quite a wide price range for these different units.  If the job of the server is to send the digital signal to the DAC; does the server really influence the sound?

Going out on a limb: InnuOS more analogue, Lumin very detailed and analytical, Auralic slightly more subdued than in your face, although much depends on the DAC and personal preferences. I am sure others will disagree on this.

I also thought streamers shouldn't make a difference, but my friend @ctsooner, has found this to not to be the case.
So, different brands of streamers do have an inherent 'sound'.

I have been considering replacing my QNAP with a Roon Nucleus. Do you mind sharing why you are not content with your Nucleus?

Not big differences. Only you know what you can hear and what features you will use.
Make a case for change besides upgrade-itis.
