UPDATE:
In my post on 4/30 I mentioned there was a Pass Labs XA-25 OTW.
Well, it's here and has been up and running for about 3 months.
If you have speakers that SUCK power forget it, but for the JBL 4367s the amp is great. Compared to the AHB2s the XA-25 draws you in. At times with the AHB2s I felt I needed to put up the yellow caution tape, "Do Not Approach." Not so with the XA-25. If I want louder, moving from mid to near-field does the trick. Near-field with the AHB2s is a bit much.
But for a party on the back porch I can open the windows and turn it way up with the Benchmarks. They are more convincing at loud levels.
