@davidmolliere I can't argue with what you're saying because I don't know how much burn-in the pair that I've tested had. But - it wasn't fresh out of the box and it was a demo so if Vegas really need 200h then either store or manufacturer screwed up putting up for tests a product that doesn't sound as it should.
Anyhow - I'm guessing you didn't hear R2pro the right way either... It's very hard to find right synergy for them. They can sound great out of good smartphone, but when you find the right DAP, then the magic begins...
If you have a chance listen to them with Colorfly C4 (via 6.3mm jack) - it's an end game pairing when it comes to natural, musical, organic presentation. It still won't pack a punch like Vegas but that's not the point.
Andromeda is more widely praised than Vegas and I'm sure I've heard this one with its full potential and still choose Flares (old ones).
When it comes to clarity, details and layering, try R2A with iBasso DX100 and you'll be blown away. Another end game pair. But still Vegas will have an upper hand in punch and probably texture.
When it comes to comparing Vegas to new Flares... My guess is Vegas will loose on all accounts. But that's just my guess
It's great that we have such a great selection of audio gear...
