I agree with Thesoundhouse. If you are set on Pass, I would go with the XA series. I too have the X350.5 and I have the Pass-addiction as well.. My friend had a pair of Amatis and he had been wanting to try the X350.5, but we weren't too keen to hoist the beast over to his house before he moved overseas.
My impression of the Amati in his system (with Einstein preamp + BAT VK-75SE monos) was on the sweet side. So I am not sure Pass would be a good fit. But with a more analytical/neutral preamp like the ARC Ref 3, it should balance out.
My only real experience with the Strads was in a Magnolia Hi-Fi in Seattle where it was driven by all McIntosh stuff, and it didn't sound too good with that combo in that room.
