Comparing the two, the Andromeda is the cleaner sounding of the two, while the Sirius takes a more musical approach. The Andromeda is slightly brighter, slightly more detailed and extended at upper frequencies. Bass on the Andromeda is slightly more forward and tighter. Midrange of the Sirius is warmer, making the Andromeda midrange seem colder in comparison. Sirius has a more engaging midrange, and sounds better at louder volumes. In terms of preferences, those who like musicality, soundstage and vocals will prefer the Sirius. Those who prefer detail and extension will prefer the Andromeda. I feel blessed to have heard both. They both deliver world class sound quality

Sirius vs Andromeda – soundstage expansion nearly the same in all directions, though I feel Sirius is a touch wider, while Andromeda is a touch deeper. Andromeda has a little more transparency and slightly better layering and separation. The quantity and quality of sub-bass and mid-bass are nearly the same. Sirius has a little more body in lower mids, making sound more balanced, while upper mids are nearly the same, very detailed, resolving, non-fatigue, though Sirius is just a little smoother in upper mids. Both have an excellent treble extension, crisp, well defined, detailed, but Andromeda has a little more sparkle and airiness while Sirius is a little smoother at the top. Also, Sirius has zero hissing, while Andromeda has some.
