Returning to a hobby I abandoned two decades ago as life interfered with my personal desires.
I am currently drifting between horns or BBC sound. Two different worlds, but each intrigue me. Considering Volti Audio with Cary SLI80 Integrated while also Harbeth 40.2 with something like a VTL MB185 Series III. Schizophrenic I know.
Dedicated Room 12’W x 30’L x varied vaulted 11’H.
Your room is long enough where you can set up 1 pair of speakers on front wall and another pair of speakers on the backwall.
Rotate the chair 180 degrees everytime the schizophrenic hits.
Personally, I would ignore the BBC stuff and go with a) a horn and b) a panel llike a magnepan or something.
