WOW! Stacking 2 opticalModules between my non-SFP port switch and the ultraRendu
( >ultraDigital>I2S DSDAC) sounds amazing! Improved clarity/articulation w/o increased sibilance, clean/tight bass, … yes, it does sound like another veil is lifted. Did an A:B:A:B between old and new configs to confirm my impressions. IMO, the digital to digital conversion (DDC) to and from fiber is a legit SQ bump.
