I currently have a Denon 3802 running my Klipsch Reference III v2 Mains/Center/Surrounds for 5.1 and it's calibrated with AVIA. I have a pair of SVS 20-39 CS+'s running off of a Samson S1000. I use 13ga IXOS gamma speaker wire for the L/R/C speakers and those 3 are bi-wired, and AR Pro 14ga/4 conductor in-wall speaker wire for the subs and surrounds (I pair up the 2 cables for an effective 11ga connection). I have Blue Jeans "RCA" cables for everything else. Everything sounds clean and clear to me at reference level, which is 00 on my 3802, so would I really benefit from a 1205a? Most of the time I watch movies @ -10db on the receiver anyhow.
