Harbeth 30.1 + Sub vs Revel f208/206

hi everyone, I would like to know if anyone auditioned both revel and harbeth and ever compared directly their sound?
Id like to know opinion only by users having heard and compared both model: the harbeth 30.1 vs revel f206 or f208

Harbeth never recommends their speakers to mate with sub. They don't even build floorstanding speakers.
Not sure Harbeth "never" recommending use of a subwoofer. I recently read a thread on HUG- Harbeth User Group- where designer Alan Shaw was offering suggestions on how to set a sub up with Harbeths.
