Yes, Ralph was talking about clipping characteristics of solid state vs tube amps.
If you aren't driving the amps into clipping, then the clipping issue really isn't one.
It appears that a well designed and built tube amp in the 50-60 wpc range will work quite well with the speakers of choice mentioned. It is always good to try the amp in you home system to make a final determination.
But, there are some quite nice tube amps out there in the 50-60 wpc range.
