Ah well...
the Marantz sounded great, very good bluray image quality...but was clunky as a clunky thing in a clunky competition.
Froze often, display got "stuck", intermittent connection to the network....all fixable by pulling the plug out and switching back on.
Thought it was a firmware thing, even upgrading to latest version didn't fix it.
Shame, sounded great but had to go back.
Still picking a "last disk spinner" up, looking at the Oppo now.
