Since I have recent experience from Pi DAC through DCS Vivaldi stack, I might as well chime in. I ended up with an Ayre Codex fed by a Roon Nucleus. I have been quite underwhelmed by the Rendu products - Digital and lifeless, reminiscent of the recent McIntosh preamps.
The Codex was a massive step up in musicality, pace, as well as micro detail and soundstage over every less expensive option. Meaning full up grades cost nearly to over $10k. If I were to upgrade, I have to say the DCS Bartok is the most affordable DAC through which vocalists sound human.
As a side note, the R2R people and to a lesser extent the Chord people make me laugh. 1) are you really going to find two resisters that match?
2) a billion taps does not make your DAC sound as good as anything from DCS.
