Looks like I'll soon be able to put my A50 to the test. These are now inbound:

3.7 Les Paul's in tobacco finish. Well worth the wait!
The previous owner used a Pass Labs 350.5, of which the 1st 40 watts are class A. Said he never once saw the amp switch to AB. And given the A50 quadruples down to 200 wpc at 2 ohms (tests show the 3.7 is more often under 3), I'm fairly sure my A50 will be more than up to the task.
I'll report back once I've had a chance to play with them..
