Actually my taste is not being spesific but general in this regard. I like flat sound. Almost all the phones I have tried after 2014 have flat sound.
Except Xperia's. Here is the proof.

And If you ever had an Sony headphones they do the same tuning to their headphones. On MDR 1A, hear.on and even in their legacy model Z1R. Here is the proof:

Z1R:
"At first blush the MDR-Z1R sounds like a warm warm headphone with some treble emphasis—a bit smilie face, but not bad. May brain never did get around to accommodating though.
The bass is a bit too strong and remains emphasized too far into the midrange giving it a thick character. A moderately withdrawn presence region adds some veil to the thick bass. A lack of energy 4-6kHz leaves cymbals lacking body, and a
big peak at 10kHz add too much zing to everything and, while not piercing as would a 5kHz be, becomes significantly fatiguing over time."

And about your compliment, yes people haven't said in this froum, but some have in the A40 forum.
cagas said: "Any reviews on SQ ? i just got mine, clarity soundstage is decent. (wouldnt consider myself an audiophile) but compared to my PHA-1A, the bass impact and thump seems lacking, esp in classic rock with drum solos. This is my first DAP though so i cant compare to anything than my Galaxy S8."
themindfreak said: "Compared to my LG V20, it does indeed lack bass impact and depth however the staging is wider and treble is much more emphasized which sometimes stings my ears if the track has been mastered hot"
It has been said diffrence between the A30 series and A40 series are very minor.
And no I don't want equalastion option at first place, my priority is FLAT SOUND OUT OF THE BOX.If It is not flat sounding, then I apply equalisation to fix compansate for it.
But what I say is that It should be the opposite. That's what audiophilie product is most of the time.
There is a reason why many people hate beats headphones. Yes they are fashion statemetns along with their high price, but main problem comes from they are being colored.
If you and 100 pages of praise can't hear or resolve any diffrence than that's another story. I hope someone do the measurement tests with A30 or A40 series soon. I stand my claims.
