wilson impedance goes bellow 4 ohms which will result terrible distortion in these regions of the frequency/impedance plot. will this distortion sound great to ears, i don't know, but will definitely be not accurate recording material playback. any professional acoustic or recording engineer would be terrified by this decision. moreover, the unused power to the load will return back as a heat causing early tube failures.
it's one of the audiophile toys to try to drive giant speakers with small tube amp or set and try to convince that little set can drive anything.
