Armandido, the X350.5 is now already shipping. the Pass engineering team is now concentrating on X600.5. I have spoken to Pass Labs in the last 10 days. The X600.5 should start making music by mid December. It is likely that the new monoblocks will be shown at the Vegas show in January.
By the way, if you want to know more about the new series, I have started a thread to discuss differences between X series and X.5 series.
