Use external (hardware) EQ
Ive not encountered the concern regarding software equalization, by including two "dvx Audio" 131s 31-band 1/3 octave hardware equalizers (one per channel) right after the nuForce uDAC (Digital to Analog Converter that Ive ben using with the Audirvana App) and before the external amplifier. BitPerfect sounds, well .. perfect !
