I'm running my Wadia861se GNSC into a Boulder 1012 pre-amp. I never seriously considered going direct to the amps for three reasons:
1. i wanted a greater range of volume setting than just affording by staying near the top of the Wadia digital attenuation
2. i required the ability to switch between a couple different source components
3. the Boulder is a fantastic pre-amp, and i believe that the buffering and drive capabilities of a good pre-amp should not be discarded off-hand (especially when mated to the same mfg's power amps).
just my opinion.
