If you can stomach paying $4000 for a pair, you get your wish with the DCA Stealth.....
Dont forget it all depends on personal preferences and tolerances. For some , the Harman/Amir target might be the only sound signature that satisfies. Others might be perfectly happy to enjoy different sonic presentations that deviate.
That said, low distortion, good bass extension and a smooth FR shouldnt be (and isnt) unobtainable at reasonable price regardless of what the sound signature is like out of the box. At which point, its not worth worrying IF you can and will EQ.
