Andrew, I think they are equally great. While both display the known Pass qualities of good bottom end grip and the airy top end; the X350.8 is slightly more neutral sounding versus its smaller brethren. In comparison the X250.8 has an audibly more clear sonic similarity to the XA series.
While I do Iike both and could even imagine something like Soulution or Nagra in the future, and don’t mind a neutral sound signature, the X250.8 is a good way to enjoy a more open sound signature in the highs while maintaining the ability to maximize vocal jazz in the midrange. Further, I listen mostly to vinyl and find that the X250.8 just very slightly better conveys the vinyl qualities.
As to the power, I believe even with the X250.8 I will be hardly leaving class A, as I typically do not listen at very loud volume levels and my music room is not very large. And 500 wpc on the Magicos is already plenty. I do like the fact though, that the Pass adds 150 wpc @4ohms compared to the Ayre, as that is very good for dynamics, speed and transients.
And funny enough, a minor but existent factor was the lesser power consumption for the sake of the environment (I know), but as you see I’m still a Class A guy and not ready for Class D just yet [emoji3]. The importance of that factor will however grow for my system - not because I have to, because I can.
