Yeah, with the black filters and some EQing the PFEs definately aren't light on bass, the bass is just very quick and precise, maybe not so punchy, which is why I am moving to some dynamics. The bass is there, and there is plenty of it, it just doesn't have that extra 'oomph' that the dynamics have, and I think that I will get a fuller sound out of the dynamics (Atrios in my case) than the phonaks, which are full but not as full in the lower end. That being said, i haven't heard them amped yet.
Also, with some sources, notably my iMac, the sound is very bright and can get fatiguing, especially when listening for 5 hours hehe.
Out of my 1st gen touch the sound is a bit darker and more listen-able, and with the bass boost EQ, the sound is good for most things besides the distortion.
EDIT: There is a large chance I might keep both the atrios and the phonaks.
