Well, I performed a little experiment involving my wife. My wife is not an audiophile (whatever this means) in any kind of way but she has around 20-25 years of experience as a live performing artist, vocal, dulcimer/Dobro/acoustic guitar (American bluegrass/roots type of music).
Anyway, she is pretty much only acquainted with a pair of relative cheap JV IE M's combined with an pod 5.5 (Yes, it does have the the good old Wolf son 874x chip implemented) as her main gym rig. My wife has absolutely no idea what I'm listening to/through or how/when I'm spending my money, let alone the relativity of pricing of portable audio gear. She just judges music by her ears/experience and we don't share anywhere near a similar interest in Fifi gear although we do on occasions play acoustic music together and do other things..like raising kids.
So, I let her choose her favorite tune listening through her very practical setup which she was absolutely very contend with. Then I let her listen to the same song while using the N4. It was a country tune by Alison Grass if anyone needs to know..
Okay, to say it bluntly she was very impressed and she offered me sex right away, which usually doesn't happen since I have to beg for it...
No, she was floored by their sound and the first thing she said was actually "how much did you pay for these". I immediately asked her how much do you think they are worth/priced compared to what you heard a few seconds before?
She then answered very quickly.. $250, remember she has no clue about diminished returns or anything related to HiFi portable gear and coming from some $20-30 IEM's. I was seriously considering taking a brief visit to to our local bathroom before I told my otherwise lovely wife that the N4's actual price are $450.
All she said was that's okay.. "since I have just bought a $450 handbag that I didn't tell you about"!!
What's my point with this otherwise tedious story.. which is actual a true story, pricing included. Value can be a very different perception to each individual but quality will hopefully always contain.
Of course I don't truly mean the above statement, but in the case of the N4 it comes very close.. Sorry, that I avoided any notion about what the N4 really sounds like.. since I strongly believe that is something we should decide on our own. I'm very impressed with the N4 and when my wife gave the N4 a true thumb up for something she thought was slightly expensive/overkill, why not..
