well if you wish to blow up your drivers, which is the 1800mW you mention, then indeed you need another amp. but I'm no sure it is the usual way to estimate power needs ^_^.
as for anemic bass and narrower dynamic range, I've seen a great many posts claiming the weirdest things about extraordinary power needs without evidence or any objective reason, but I'm yet to find even one of those guys with an explanation that doesn't crumble upon scrutiny. they are always very sure of themselves, but would miss "small" details like proper testing, or how the 2 amps used as "evidence" in their experience are totally different designs, components, and specs. nothing is the same, but somehow they magically can tell that all the audible differences must come from the power spec . I wish I had that skill to turn wild guess into a certainty.
so if that's your only reason to want an extra amp, I really advise against wasting money. even more so when this headphone isn't your typical low sensitivity and/or high impedance headphone that powerful amps are usually designed to drive. quite a few arguments could be made about the risk to get objectively worst sound because of those 25ohm. you might want an extra amp, but maybe one designed for IEMs with real low impedance and at least 2Vrms into 25ohm would be a better option overall. I personally wouldn't jump on a power amp for that headphone without a few measurements into that load or the ability to test myself.
that said, if you find an amplifier you like(sound, look, synergy, whatever), of course you should follow your own preferences and make yourself happy. and of course if you have a good amp, it's very possible that it will do a little better than what's inside the A16. but don't fall for the "more power is always better" nonsense. half the advocates of that idea don't understand the first thing about electricity.
anyway, all this is my opinion based on very scarce specs. I haven't tested that headphone, nor the A16. but the specs we have do not scream to buy a new amp for this headphone.
