918 variant shoot out?

[dissonantdissident]

Anybody done a shootout between the various 918 opamps that are now available? Just wondering what differences people hear between the two whistle rocks vs. the two GAR versions.

Well if they sound different, then one of them has a problem!
It would be better to examine them with a high frequency O-scope and measurement equipment.

It is a lot of work to design and perform a statistically significant listening test (double blind).

Then the behavior of any serviceable op amp will be dominated by it's feedback network transfer function and component quality, then output loading, plus PS integrity, and finally maybe even physical PCB layout.

Good luck, you will probably learn something from the effort (maybe not what you expect).

Is the whistle rock even offered anymore ?
