Wow ... I didn't expect my question to cast us into a moral quandary. However, all this mention of surreptitious slithering and other sibilant descriptors does get me really interested in delving into the dark side of audiophilia :)
On a more serious note, thanks to everyone for responding. This is the first true high-end system I'm purchasing for myself (I'm still using the old Bose 550 receiver I bought more than 20 years ago with my paper route money - it may not be high-end, but it's served me well for a long time), and it's a bit intimidating when there are so many choices and a huge spectrum of prices.
Thanks, Tiger for the formula, and Bongofury and Phaelon for the additional suggestions. I'll see if I can find those brands locally (I'm in Denver) to listen to them.
