CA 540r - CD Playback - PCM


Novice Member
Morning All,

Quick question that'll hopefully:

A. Put my mind to rest

& B. Keep the other half happy as I might not need to spend any money!

Currenty have my Marantz CD5001 OSE hooked up to my 540r via the CD/Aux Analogue inputs. When the signal hits the amp the display briefly shows PCM.

At this point is the receiver doing anything with the signal other than amplifying it, am I correct in thinking that a PCM signal is uncompressed and I'm getting everything out of my speakers that the DACs within the CD Player have produced?

If not would I see any real gain in swapping the amp for something with a 'direct pass thru' function?

Cheers in advance!
