Nuforce Icon vs. KEF Picoforte

Has anyone been able to compare these two devices?
I've assembled a "transportable" system composed of:

iPod Classic 160
KEF Picoforte dock/amp
Gallo A'Diva Ti

I'm wondering if the Icon would be any better.
I loved the look of the KEF Picoforte stuff but found it lean sounding with the "egg" speakers that it it comes with. (even paired with a subwoofer). I'm guessing that amp just needs speakers that are both extremely efficient and perhaps a tad warm. and a sub.

The Nuforce family sound is clean clear detailed fast and not euphonic in my experience, but have not heard Icon (yet).
