Hi. I stream music, watch films, some TV via Apple 4K TV (Apple Music), most TV via Sky Q box. Both Apple TV and Sky Q box, HDMI to Panasonic TX-50X700B TV, then optical to Cambridge CX A60 amp and new B&W 607 (non anniversary) on three pillar Atacama stands. Sound is good, but any ideas to tweak further without too much expense? Cheers and thanks, Graham.
