Arghhh op amps... NE5532 is fine you can't hear the distortion in them it's in micro volts!
You can't hear the difference between two reasonable op amps, it's all marketing.

Ideal support circuit design is different per each different model of op-amp, so it is probable that the majority of the differences heard by chip rolling is located in support circuit accommodation or mismatch. It could be better or worse, but of course there will be some difference. Those who explore long enough will find audibly favorable differences and then claim the replacement op-amp is much better for everything, but actually their favorable replacement was merely more suited to their application.
Therefore, after chip rolling with this result: "the sound is a lot better than the stock setup" means that this DAC application didn't include ideal support for the op-amp. Or, it could mean that those modern production NE5532's used in the DAC application are significantly different from the documented performance of Signetic/Philips NE5532's of the past, all bets are off with the new models, and in that case the chip rollers are simply populating their boards with non-fake op-amps.

When was the last time you used formulas to determine external components with the numbers from the op amp datasheet. Proper implementation yes. If not its not compatible.
You cannot tell the difference your head makes it different.
Do you expect new production clones/counterfeit to precision match twenty year old datasheet specs?
For reference:
New Asus Xonar's production is circa 2012.
The last authentic NE5532 was circa 1992.
Sockets are for removing counterfeit chips.
