I don't know that 'logic' has much to do with it. Nor 'accuracy'. This is a highly subjective hobby. To some folks, 'accuracy' is everything and can be measured with an oscilliscope, a microphone and a sound-pressure meter. To others it's a far more subjective realm of judgement that is more about the experience of how a system sounds, and then there is every degree of variation in between. My ideal review format would have a group of reviewers without financial agenda (of course), who each have their own spot on that jury spectrum. In the review of any and every component, each of them would contribute their personal views which one would be able to reference against past preferences and how those preferences may relate to their own. Also, it would be nice to have components that compete against one and other rated together as a group, much like Consumer Reports does with mass-market products, but on a smaller scale. The rags do this to some degree, but more often isolate the review to only one reviewer, and most certainly there is the unavoidable conflict of interest of the financial matter of advertising paying the salaries of the reviewers. A review in this formate might have a face-off between Audio-Aero, Cary, Muse, and Wadia CD players. Each would be compared within various diverse systems by the same group of reviewers, and each would give their viewpoint of how each player stacked up against the other. As it stands now, we usually have a single reviewer, doing a review of a single component in their reference system with a variation or two, and comparing it to whatever else happens to be on hand, or may have been recently reviewed (in which case they may be compared from memory). And perhaps there may be a sidebar where another reviewer may chime in with far less detail than the overall review having auditioned the component in an entirely different room and system. Of course this will never happen. There are all kinds of reasons why not, most having to do with difficulty and impracticality and expense of conducting reviews this way I imagine. And or course then there's the pressure of the advertising-dependent journal.
I don't think I'd rather be reading reviews of constant drueling praise, singing that the glory of god has been bestowed upon each and every component under scrutiny. That we should love these beautiful children for all their flaws as well as their assets because each and every one was conceived in heaven and constructed by li'll elves with soldering skills handed down for generations. What I want to know when I read a review most every time that I can think of is just how does this component stack up against what else is out there available in the same price range. How does this component interface with different types of systems and music, and who is making such a judgement, and what do others say who may have different tastes and preferences.
As far as billet aluminum, glowing blue knobs, fins to write home about and all of that high-tech ornamentation, I see nothing at all wrong with any of that since there's obviously a market for it, and there are those who value form as much as function. Nothing wrong with that at all as long as you realize you are paying for both.
Have components started to decline in quality/price ratio? I don't know. I've been pretty impressed with what not a whole lot of money can by these days in the high end. The threshold at which investment-to-improvement is low enough so that many folks can have a very satisfying taste of what others can afford in spades, without taking out a second mortgage. I am very impressed also with the fact that, to my ears, I can get great pleasure from some vintage components that are over 50 years old sometimes in terms of their design and technology (I speak of the likes of Klipsch, Quad, Dynaco, etc......and of course the LP's/turntables which many of us adore and prefer over digital options). What other realm of consumer technology can boast such a staying-power.....perhaps classic cars might be an example, though if I was driving any distance at all I'd rather be in something more modern for the comfort and convenience, not to mention economy.
Not sure where I'm going with this, but that's what came to mind when reading the last few posts. A very enjoyable thread indeed.
