There's definitely a strong family resemblance, but Stellia have better extension and speed - particularly in the bass. Also there's significantly better detail retrieval with the Stellia. Imaging is much sharper too. I've lived with the Elegia for a year (bought at last year's show!) but really strongly prefer the Stellia. For example, in the recent Berlin Philharmonic Tchaikovsky 6 you can not only hear terrific instrumental separation and dynamics but you can hear the hall much better, in fact, I noticed the conductor breathing. Another recording was Joyce DiDonato's "Faust" - the articulation and speed is at a whole other level than the Elegia with vocals. Bass is tighter, faster, better and more tactile. The Elegia is a really great, underrated headphone, but the Stellia is better in every regard I can think of. Haven't taken them off in 3 hours now!
