Guidocorona, I had X350 and X350.5 in my system before, the difference between them may also refer to X250 and X250.5, I suppose.
X350.5 has more extension on treble and bass, especially in bass side, much more detail. But still keep the same tonality of PASS Amp. The balance is still as good as previous model,
