Two very different speakers. I own Forte IV and have owned Revel M106 . I recently listened to a Rega P3 through the Revel 226 and thought it was a little tipped up on the top end.
The problem with the Revel in my opinion is support. Waited months for them to send out a replacement grill under warranty and it was only a grill, not a driver ....
I then bought Heresy III after the Revel, my daughter cranked it up and took out a midrange driver. Klipsch sent a driver to my dealer a few days later and I installed it. More and more companies are selling stuff without a gameplan for support , Revel told my dealer they had to open a new pair for a grill. Not very reassuring if I needed a driver down the road.
