I am wondering which of the components may represent the weak link to my music listening nirvana? ... Since I'm more interested in the musicality of the system, listening to a mix of female vocal, rock, and dipping into the ambient realm now and then, I'm considering the replacement of the Rotel RKD-650 with something in a nice stereo configuration, possibly 3-channel to pick up the center.
Thanks everyone, but we are getting a little off topic, IMO. I have fiddled with speaker placement for several weeks to get to where I am with them, and I am not really interested in working on the surround system. Let me ask this, then, if I am going to replace the 650, would a foray into the world of tube amps/monoblocks be a worthwhile investment? I see the Prima Luna Prologue 7 for $1.7k, what are your thoughts on this matter?
