Replaced standard feet on Denon & Primare with solid brass cones,bases under components are actually cutting boards.Got a local carpenter to make speaker bases - all raised by same brass cones. "Bass Traps" are foam mattress cut lengthwise. Result- sonic images more focussed and more easily identified from each other,removing TV and stand gives more coherence in centre of soundstage and left/right sweeps are smoother and more natural-all in all a good day's work!
