Being a former owner of the Twin Towers Reference, I would strongly recommend the Inpol2 (supposed to be similar to a Twin Towers on steroids). I would still own the Twin Towers if I had not changed to innefficient speakers (Dynaudio 1.3SE's). I'd contact Von Schweikert to confirm your VR4jr's are efficient enough... I'm thinking they will be fine.
Pathos Integrateds
I'm considering going from solid state amp and preamp to a hybrid Integrated and have been looking at the Pathos amps. There's a $5k difference between the Logos and the Inpol 2 with the Logos having 110 watts compared to the Inpol's 45 Class A. Is the Inpol that much better? I'm using a pair of Von Schweikert VR4jr's.
