Those specs mostly apply to dynamics - planars are different.
Planars behave even more like resistors so those specs apply even MORE so for planars then for dynamics.
Do you own the Arya and have you tried giving it more power???
Not the Arya but Edition XX (similar construction) and several other planars.
As I explained... you cannot 'give' headphones more power. You can apply a higher voltage swing so it will go louder.
When a higher voltage is applied more current will be drawn.
Though the Arya can't use and isn't given the whole ~12 watts (or...damage), it did soak up quite a bit of power from the Emo while being volume controlled from the Gustard.
Soaking power ?
How could you objectively tell ?
Did you monitor the drawn power or the output voltage of the amp ?
I got the sense of the Arya being unfettered by power limitations - and it was a very fun ride. Don't knock it til you've tried it...
You got a sense... unfortunately that is only what it is. A sense.... non-sense.
That there's a bass boost via Harman is only an assumption - not everyone likes the Harman Tgt FR.
When the Arya (or any other hifiman planar) is EQ'ed to the Harman target you can be certain there is a substantial bass boost needed. This is no assumption.
Indeed not everyone likes the Harman target. This is already blatantly obvious when looking at Harman research.
I mean that many HP amps are between .5W to 4 watts, but the Emo has ~12W on tap @ 32 ohms.
Every speaker amp has the same when you connect a headphone to the speaker taps. There is nothing new about that.
In the end ONLY one thing matters and that is how high the voltage swing is across the headphone.
It does not matter if the amp in question can swing to 5V or 20V when the output voltage never reaches levels beyond 4V for instance.
The Arya was able to utilize some of that ~12 watts (over and above the ~4 watts of most "powerful" HP amps)
Assuming you were playing at impressively loud levels (no EQ) and reached 120dB peaks you would be drawing 0.7W. Admittedly this is some of the available 12W. When you would be exceeding 4W (11V voltage swing) your ears would be blasted by 128dB peaks. This is NOT pleasant to listen to and you would literally throw the headphones off. So it is extremely unlikely you would ever exceed 1W.
to the effect that the Arya altogether sounded uber-dynamic in the bass and tonally richer otherwise. Keep in mind that many Arya owners have noted that the Arya v2 (and older) suffers from a sort of polite and lean bass presentation - but not at all polite or lean when given the extra power, it becomes a beast in the bass.
You do not seem to understand the 'power' thing at all.
Power = voltage x current.
An amp supplies the voltage, the resistance of the driver determines the current that goes with it. Voltage x current is drawn power.
I'll quote Scotty... You cannot change the laws of physics.
