I used a Pass X350 for a couple of years (after moving up from an Aragon 8008ST). The improvement in the mids & highs was so stunning it sounded like a new, much better, speaker... smoother, angelic, sweet, airy, etc. Vocals were suberbly natural.
Curiously, the bass was a little too prominent until after a long break-in (3-400 hours), but then settled in nicely, especially after I switched to Cardas Golden Ref speaker cables (and interconnects) at the time.
The bass is said to be much more tuneful on the new X350.5, so I would give that a try if I still had 10Ts.
Soundstaging was about the same on the Pass, which is not the 10t's strong point (tonality and a non-fatiguing nature is where they excel, IMHO).
Good luck!
