Interesting impressions. I had both before deciding the stellia were a big enough leap in performance to warrant the premium. I had the elegia for about a month before the stellia and enjoyed them a lot, dynamics, tone and stage width were great, detail about and resolution were good enough.
When the stellia arrived I was a little underwhelmed although they immediately sounded more open and detailed making the elegias sound closed by comparison. They did sound a little muddy and the bass was laking quantity and resolution, but this all changed at 50hrs+. After this they stretched their legs leaving the elegia behind in every department. So much detail, only matched or bettered by totl open backs, more extension at both ends than the elegia, as I’ve mentioned buckets of well resolved detail and most pleasing is the texture and weight of each instrument. Tone is lovely and the whole presentation is beautifully coherent and right, with zero fatigue even over 4-6 hour listening sessions. I’m definitely repeating myself from earlier posts, so I’ll leave it at, I haven’t found they’re limit in terms of scaling with better components and for me they've been worth every penny of their premium
