Wow cant believe i actually found other Mission owners here in the US !
I have a full set of 78 series in y main room for both 2 channel music and HT : 783, 78C, 78ds and I also have 781 's in a second room just for music.
They are paired with a Marantz preamp & Outlaw audio amp (had a marantz 9200 powering them until recently) I really enjoy the warm rich sound of this combo.
I am no getting into Atmos, DTx , etc... looking to add some new surround backs (currently have some cheapo spaekers) , front high and rears or possible some in ceiling speakers.
At a loss of where to start looking for speakers with the same timbre match. ...PSB, Paradigm, Wharfedale, Boston, etc... Does anyone have some ideas ? All i know is I auditioned Monitor and Klipsch many years ago and I HATED the very bright sounds but did like both Paradigm and JM Lab (now focal?)
