I have an Asus STX II and an EVGA NU Audio sound card in my audio pc (both with linear low noisy power supply).
The sound of the Asus STX II soundcard definitely better than EVGA NU Audio card sound. STX II sound very detailed, open, airy, the sound stage huge, vocal vivid, the sound real and musical. No question for me the Asus far better.
Any chance u tried replacing the op-amp of the Nu audio card with the Sparkos or MUSE op amps found on your STX II? I think the Nu audio's default op amps are holding it back
