You WILL have to upgrade your receiver. 5.1 is done thru a digital coax. Single line. SACD is 6 discreet channels. ie. six lines, six connections. Hence, new receiver.Are you sure? Having all 6 discreet channels would probably be the ideal way, but I don't think it's the only way. There are SACD-capable home theater systems with 5.1 speaker systems [1,2], which I'd presume simply split the 6th center rear channel over the two rear speakers, as well as SACD-capable DVD players (such as this rather expensive one or this cheaper one that also has 5 channel analog output) that have digital coax outputs and should be able to hook up to any reciever with a digital input.
