You probably read this already but look
HERE and
HERE. This may shed some light on the players in question (Denon and Pioneer).
Unfortunately, with my 27” old tube TV, I can’t really say anything meaningful about the picture quality.
As far as sound of my system goes, I must say that Outlaw ICBM brought the biggest improvement in my sound quality. A few of my friends (that had the chance to listen to all the players in my system) share that opinion.
