I think the sound difference would be Minor or get it for remote and display or put the money into a new Dac or transducers IEM, HP ect…
I love my Combo of @geshelli_labs J2 AKM and A90D

Stick with the OG and be happy, the difference is rather small - not enough to warrent a “upgrade”

as someone who didn’t like the OG A90 the A90D is ok it’s a bit better but it’s still the same product with some upgraded specs essentially.
Greetings …
got my a90d for days now…
plugged via xlr to su9 dac
comming from og atom amp
im surprised how an amp
can change the headphone signature
and performance …
itbrought life to my hd6xx
and blon b20 planar
bass is punchy controlled never bloated
trebile notes are cute and delightfil to ears
instruments are sperated and there is
enough air between them.
soundstage cant be judged
since im using su9 and narrow staged HP
yet i feel there is more depth and width
the lazy thick sound of my planar
replaced by airy enjoyable one
always thought hd6xx lacks some clarity
and bit slow in crowded songs
yet a90d gave it all clarity and speed it needed and it never felt congested .
recommend using hd6xx on unbalanced
output since balanced feels overly clinical
and accourding to power calculators
u do not need more than 2 volts to reach
very loud levels.
thats it for now thanks.
