Yikes! Downsizing is tough. My Chorus IIs have been in storage since 2012. I prefer the simplicity of tube separates or integrated. Tube receivers are complex and not many techs enjoy working on them.
Although I have never owned RF7s, I never disliked listening to them. Cornwall and KLF 30 and oddly K Horns were the only poor sounding Klipsch demos I have heard in 40 years. The RB75 I always considered with my 12 inch sealed sub.
From a historical standpoint PWK being involved in the design of the Chorus II would lean me in that direction. Scott has my favorite phono section of any vintage tube amp, although k have never heard a pilot. Fisher being a distant second place.
No wrong decision here as long as you get the crossovers rebuilt.
