Well this is a point many fall out over, but what you have raised here is actually the point most people completely miss when "upgrading" ... the Hi Fi forums around the net are full of the same questions and people searching for that elusive improvement....
The problem comes down to not the equipment, but how people listen or judge a system. People try and "compare" Hi-Fi equipment, big mistake, you should judge musical performance, and which one is better.
What you are suffering from is try to judge a system by "how much" of this or that it does, more bass, wider soundstage, better projection, all meaningless Hi-Fi BS....
Start listening to the musicians, what are they doing, can you follow what they playing, can you sing along in your head, keeping time, and reproduce what's played....
Start judging systems and components in this manner, ignoring the traditional HiFi attributes, they will take care of themselves, when the "Tune" is correct.
Now the old hacks about here will have know where this posting was going

..... But this has all been the corner stone of Linn’s marketing and development methods for over 30 years, some support it, others stick to fingers up at it..... But your question asked in all innocents seems to suggest they have a point !.....
