I know that this has been discussed by many on this forum (Keith, et al), but help me with my situation, I have the Sony SACD 222ES (sorry, didn't get the 555, but it sounds great to me) and have a Parasound AVP 1800 pre/pro. It sounds like the best way to set up 2 channel SACD and redbook (CD) is using the 2 analog outs in the SACD player and going into 2 analog ins on the pre-amp. My question is this, how do I know if my pre-amp has a TRUE analog pass through (that is supposed to sound so much better VS using the 5.1 analog INs or the digital IN). I have a bunch of RCA inputs marked "video1, video2, video3,audio1,audio2,audio3" then I have the 5.1 input button, then I have 2 Coax (digital) and 2 optical (digital) inputs. As I understand it, some say that it sounds better to use the player as a "transport" and let the pre/pro recieve the digital signal and now OTHERS are saying totally differen, WHY??? I know that my parasound uses the burr-brown DACs (I guess they are supposed to be really good, for the $$ that this pre/amp sales for ($1000)). What would be your hookup advice?? btw, I have CDM7NT speakers and a Rotel amp any help would be appreciated.
