I find sound quality to be neutral-bright. Some sizzle and harshness in the top end. I run them bass heavy songs with Topping G5 overnight, so if you are believer off burn-in, it's done before i test.
Good post - but a couple of things:
1) You
just got them, they
need at least ~25-50 hours of bass-heavy music or pink noise
before they even begin to open up - "overnight" is not at all enough. They will continue to change up until 100hrs or more - Hifiman recommends ~150 hours. This makes a difference from their brand-new presentation - yours are brand new...
2) I've NEVER had much luck with any of Topping's amps for the Arya (or any IC-based amp really). I had the OG A90 and a Monolith '887 beside my cheaper Magni 3+ and Emotiva A-100 (resistor bypassed). The cheaper discrete Class AB amps
dusted both IC-based amps - especially in timbre/tonality, texture, naturalness, and not becoming bright/harsh in the treble. Neither of the IC based amps sounded like "real instruments" and both left a lot of spatial cues behind. Now I've got a discrete Class A Gustard H20 and that has dusted them all in those areas I just mentioned - but now they also have much better bass depth/detail/texture, a more natural timbre, and an even more extended treble without harhsness. You've got a ~$299 Topping portable/AIO - and not to rib you - but the Aryas will
expose what they're being driven with. Your Topping may be a contributing factor in the bright/harsh/sibilant that you're hearing. IOW, your chain/amp quality counts more with the Aryas.
3) Your burn in phase hasn't even started yet, LOL....
They slam equally good and no change in soundstage width depth imaging etc. with Lightning Dongle vs. G5. Anyone who says linear amp makes difference with lightning dongle needs to get their ears checked.
Keep them playing overnights for a week or two then report back with what you've heard.....
sounds good with everything except bass heavy modern genres like hip-hop and metal/rock
Again, they will get much better with more time - especially with bass heavy music. Metal/hard rock really depends on the
quality of the recording - they will not mask bad recordings at all......
Finally, they're brand new
to you. Most new HPs will take new owners at least a week to
acclimatize to their new HP's sound signature.
After they've burned in with bass heavy music for at least ~50 hours -
then you can listen to them exclusively to better get a gauge on their
truer sound presentation. Out of the box and brand new (even after 1 day, LOL) they're a little
tight-n-bright - they take more time to develop bass depth, bass texture, bass dynamics, mids layering and detail, and an expanded stage. You don't have to believe just me - just ask some other owners......
