Content is a relative term. I am very happy with my two channel system now, and while there may be changes in the future, there isn't anything in mind now. I am just enjoying the music.
However, now I am upgrading the HT/surround sound/spare stereo system. I just added my two previous amps to it to drive the fronts, and that required buying a two shelf Mapleshade Samson rack to sit next to the 5 shelf rack. Next is upgrading the speaker cables, which will most likely be Shunyata Zitron Cobra all around. I just added a Shunyata Anaconda AES digital cable between the Bryston BDP1 and BDA2.
I guess by the time that is tweaked, it will be time to start again on the stereo.
