Both.
I’ve had my set of SR1a for a year now, and they’ve got >2,000 hours on them, so yes they’re more than burned in by this point … and were before the first HSA-1a showed up.
So there was no break in listening to them, I was just running them off my big Chord stack (including Étude → SR1a interface) while the HSA-1a was away. And sometimes off the Jotunheim R.
