with options 1-4 on my playback system I liked the SGA SOA's a bit more even though the red dots seemed brighter. Overall I liked the brick the best though. Thanks for taking the time to do this comparison.

Is it ok to use the Hardy 990 with the hair all audio elements series?

I agree with Jeff that if your goal is to do an opamp "shootout" with a circuit using a high ratio input transformer, you're setting up the 990 at a disadvantage. One of it's key features is low input noise and it wants a lower impedance at it's input to achieve that.

You can use whatever you want and you may dig it, hate it, or not really care. But is the realm of a "shootout" I wouldn't compare a 2520's and 990's in the same circuit.
