I think I have seen reference to a few other units that are compatible with Dirac's Bass Module, I am just not certain who is using it beyond the HTP-1.\n\nSounds like in this case Onkyo may just have basic and would need to support them bass module or may just be basic only. \n\nUntil I had the Yamaha I’ve always had Onkyo and Pioneer previously so the new Onkyo intrigues me. \n\nUnfortunately due to some unforeseen life changes in my family my viewing room\/home theater has been taken over for a bit by reruns of “The Love Boat” but man those horns in the theme song sound just sandy!
