Hello Tbg, Yes, in an ideal world personal auditioning in one's own system trumps all forms of verbal recommendations of course, but I think what keeps a lot of these threads alive is people being able to add their personal listening experience descriptors to a "What do you think about X" inquiry. Using terminology such as the 1980's vintage CJ amplifier is "a little fat/tubby in the bass with added ripeness in the mids" or that some brand of SS amp has a very "quick or incisive attack" or "razor sharp imaging" (pardon the old-school generalities) can be helpful in pointing people towards or away with particular makes/models. The fact that people here all listen...is far different than explaining to a blind-from-birth person why you prefer the color blue to red...
System synergy complicates things more, of course, but the sheer number of variables intrinsic to this hobby already add tremendous complications...as well as bring about "options" in personal taste...
Again, I think most of us are probably in agreement about the limitations of "Discussing Listening...".
Nevertheless these posts thrive under the common thread of our musical tastes and associated systems and equipment. Just 2 cents.
