Jim,
to my mind you make excellent sense. My compliments also regarding the rationality and equanimity of the phrasings by which you presented your post. My thoughts in this matter are far more cynical and would hardly prevail before the critical eyes of the resident censors.
On the other hand of course we do depend upon what others tell us, especially if we are not as deeply informed as we perhaps should be, when we are seriously engaged in this hobby and deeply drawn into it. It is only in time that we learn to discern and form opinions of our own. You can see this by closely following the work in progress of our eldest and most experienced members, should they present their systems to us. Most of them, I find, no matter within what price range, are highly eclectic, selecting their gear often enough not so much within the mainstream, often more from what you call the "quiet" brands. This strikes me especially of Audiogoners, whose love of music seems to exceed their fascination with the gear, although they are mostly highly knowlegeable as well as far as "the machines" are concerned.
The more you know, the less you will fall for the hype of the advertisers and meet the accolades of reviewers with healthy suspicion, but since you wish to be informed, in time also the "quiet brands" will find your attention, often enough on these pages, because someone has discovered a "sleeper", which one can try to be informed about and dig - perhaps also aurally - into.
Thank you for starting this thread. I hope you will be rewarded with a lively discussion.
Cheers,
Detlof
