Later, or more current, can mean better when it comes to digital playback.
The item as I see it here however isn't so much that, but more pointed towards the interface compatibility of two items.
The only thing you need to know here is IF the Krell can decode the high def audio signals input to it from a BR player... and if by coax.
Simple. Call Krell and ask them.
other wise, you would have to rely upon the processor in the player and connect via analog cables rather than digi ones.
My understanding of the newer BR codecs is that they are transmitted by 1.3A HDMI, or not at all... I could well be wrong about that however.
First things first... does the gizmo have the decoding abilities?What interface is required for transmission of the information into it's processor?
There after, considerations as to build, technology, power supplies, etc, will give you some better insights as to which way you would prefer to go in that respect.
