I used to own the Perraux, liked it but sold it due to getting a higher end OTL tube unit (Audio Valve RKV).
The Perraux has plenty of power, you won't have to worry about driving Senn's high impedence. And your thought on bass is right, it's strong with the Perraux.
The Perraux DOES have a softness or warmth to it (once fully broken in), reminiscent of tubes, though not quite as lush.
I haven't heard the X-Cans v3, but it seems to pick up some nice reviews or comments (Stereophile, a couple on www.head-fi.org). It MAY have a slightly better in-head soundstage than the Perraux, something I found that was bettered by my RKV, and also my other headphone amp, Ray Samuels XP-7.
BVut if you want a slight warmth, and value a strong balance and accurate tone, then you won't be unhappy with the Perraux.
I would suggest hopping over to head-fi, or www.headwize.com, and search for the X-Cans comments, see what you find.
Lots of luck.
