Hey , I judge the sound by myself , you judge the sound by yourself but we could have common area in our view if we be trained listener, do not search criteria if you believe good sound really exist. biased opinion is between beginner listeners not professional listeners.
so after all it's your opinion ain't it? come on man! 100 people might have 99 different opinions. we Audiophiles are such an elaborately metaphysical creatures. even highly regarded ears have points of conflict in between.

i should say again and again that good sound exist and our brain detect it but if we try to describe why the sound is good our ability will be restricted by our language. i just try to share my subjective view.
I think the level of listening pleasure for each listener is the key. that's it.

defining sound categorization is not easy and i told you these words are simplified version of my idea about sound. our brain is very complex and sound of systems is very different in out mind . i try to detect what thing in the sound make me more happy.
the point is that the listener doesn't need to have a certain description of a good sound at all. his feeling while listening will tell him everything.

i do not agree "listening fatigue" is differ from one person to another person.
enjoyment in short period of time is different between listeners but long term satisfaction is unique to all and in long listening term all listeners sound reaction is similar.  
 your opinion I respect that and have no argument.

my english reading is not good . i do not understand above quote. please describe it again to me.
nothing remarkable. I was just amazed how accurate you are at guessing and predicting like Nostradamus

I defined the Micro linearity as the graph shows what i mean. both dynamic and harmonic could be view in terms of micro linearity.
good dynamic is both speed and non-compress sound. speed of amplifier (Slew rate) in transient is more related to macro linearity not micro linearity.
hey , 3D image do not mean "3D soundstage with good depth" , in my view right micro harmonic make you feel the vocal has depth and it has no relation to soundstage depth.
linear harmonic refer to both amplitude and phase in frequency domain

I believe that there is nothing to concern about what you described as "micro linearity" (still a spuriously coined phrase to me). Linearity has it's own definition. we know what elements affect the linearity of an amplifier and we know all about Slew Rate and IMD blah blah blah. My point is: it's a very difficult job to design and build an amplifier with a non-linear behavior in very small scales of frequency and amplitude. matter of fact despite it's not a good thing but I'm sure it's a hard job to achieve even though a designer intends to do this deliberately but overall non-linearity is easy to get to and for sure it's a nasty thing. I think most of the non-linearity in small scales is caused by speaker impedance variance that will affect the amplifiers that have no loud-independent bandwidth.

I think i have average to good experience in iran , check my website www.hifi.ir , i listened to many systems in many setups.
DPOLS concept never read in romy site before our real experience in tehran.
one night we placed speaker and the sound became 1000 times better than past. i searched the internet for the reason and i found romy site. before that night i never be familiar with romy site.
DPOLS article was my first visit to this forum.

I'm just shocked how the heck a sound can get 1000 times better even if we are talking in a maniacal unit-less measurement system! 1000 times?! what have you been listening before changing the placement?!I think you won't get anywhere with those extravagant opinions of yours. Audio science doesn't come from east. world is not anxious for a bravado from a 3rd world country to come up with moronic audio philosophical headlines and play the role of Jean-Paul Sartre of Audio world and start spreading out all these ideas. matter of fact experts in west have been experiencing and writing books about this in a practical manner while your mama (who you love) was still wiping your nose. Slew rate, IMD, downward dynamic range and many other technical terms are all known issues so it's definitely needless and pointless to pose subjects like this that come from a narrow mind. you are trying to coin new word like "micro/macro linearity" and some other moot-points that all are worth nothing more than a baby burp. all in all a guy like you with limited audio experience with big game-changing point of views won't draw that much of interest, the same situation here. I think you'd better to try to listen to more stereo setups so you'll find out gradually what the is the hi-fi game all about. period.
guys just excuse possible typo I was typin' in rush hour ;-o
