This reminds me of a lesson I learnt having read loads of HiFi magazines in the seventies.
Enthusiasts would follow an upgrade path that whilst satisfying the need to improve one aspect of music reproduction at a time would, at each stage of upgrade, identify a new weak link in their systems. There is no end to this upgrade cycle once you are obsessed with the search for perfection in sound. At a certain point though, specs become irrelevant. It's whether you like the sound that counts.
Also, there is a danger that you start listening more to the equipment than to the music coming out of it.
What's different about this discussion is that the sound systems we use are generally expected to perform well in a variety of different conditions depending on the type of venue. I'd argue that it is futile to expect to find one product that satisfies all conditions absolutely. Good as the quality of equipment is these days, live music is still not HiFi anyway.
