I own HIghC OPA627 supermacro IV max.
But today I changed the opamps to SA5534: Laid back and Sweetness like SR-71 but with better bass control.

OPA227: Woah! I feel like I'm listening to SR-71 with blurry weak bass.

OPA627: A bit on the analytical side.

Does anybody find the same thing?

With my SM3 6 I could change the opamps so it sounded like the 71. That is one nice thing about the SM, change it to taste and mood.
