New R2R DAC

I am on the road to upgrade my DAC. Currently use a MHDT Pagoda Balanced. Want to stay in the R2R world.

Considering Audio Note 2.1, SW1X DAC II, Lampizator Amber 4, or Holo Audio May.

Will be used in a system with Auralic server, ARC REF 3 Preamp, Modwright KWA 150 Signature Amp, and Wilson Sabrina Speakers.

Thoughts and advice?

Thanks!
