I'm very familiar with the Romulus Signature and the Eclipse version with the Stealth capacitors. The Eclipse is a clear sonic upgrade. The Yamamoto can't compete with the Romulus in terms of flexibility and format options, as it's strictly Red Book exclusively. In terms of sound quality and natural musicality and engagement, Grannyring is on the mark. The Eclipse and the Yamamoto DAC provide superb Red Book playback. Both products are noticeably improved when placed on an Apprentice platform based on my listening sessions. I heard both with the PS Audio PWT which is better than the Romulus internal transport. Full disclosure, the Yamamoto is mine and has Duelund CAST output capacitors and a Synergistic Research fuse in place.
