i bought a 555 es player the other day from one call. it should arrive here tommorrow i was wondering where you guys have been buying your sacd software as well as where reviews of the disk can be found. i ask because i know that some sacds definately sound better than others, problem being im not sure which are the better and which are the worse. also, i know this will probably be covered in the manual, im a little excited though so im gonna ask anyways..... is there a difference between using the left and right anolog outs on the 555 as oposed to using the left and right out of the 5.1 set. thanks!
