Lots of people love music.
Many of them listen to music.
Some Play an instrument & Some Sing - they are musicians.
However, every musician is not [
http://en.wikipedia.org/wiki/Absolute_pitch]
Yet, they are musicians;
All people that love music - listen to it.
They do so to enjoy them selves.
What they use to listen to their music is all up to their own personal preference.
Most may listen to music on a radio or a mp3 player on their phone or some other device. They are all lovers of music.
However, audiophile are not in the category - so I feel.
They [Audiophiles] too are music lovers & like their music - but they like to hear it in a slightly more 'clear' & accurate manner.
Weather a person spends x on his set up or 10 x or 100 x or what ever, that is of no importance here - we are not discussing finances.
The issue on hand is - can 'most' people listen & tell a difference ?
Simple things in audio - phantom centre - left to right spacing - front to back layering etc. etc.
These are abilities in listening that take a long time to get right - understand & most people are not able to know what to look for.
Yet, they are all audiophiles - they are in the pursuit of listening to good sound from some audio source.
I just say, if something cannot be heard by all - does not mean it may or may not exist.
I just say - TRY IT & then decide if there is a change.
If so, good - if not then also good.
No person that tries this will have any effect on his physical being like what you suggested :-
A person doesn't need to climb on a 100 feet high water tank and jump to the ground in order to know he will die or end with a 100 fractures.
It is very very simple.
Use 2 computers - load win 8 on both.
Download the free - trial version of J Play.
Follow the instruction of set up.
Play it - swap the Ethernet Cable - Play it again.
If you can hear a change - or you cannot hear a change - good either way - at least you will form an opinion based on your own listening.
Audiophile Tag or not - how does it matter ?
At the end of the day it is your OWN MUSIC SYSTEM that you have to listen to, & if you get happy & satisfied with a NAD / Denon / Yahama etc. Brilliant - a ticket to audio nirvana was purchased for a super price - he happy & celebrate;;;
What more can you ask for ?
