Yeah, I don't mind them on cheap Fiio portable amps, but do not want them on something like the O2.

It's pointless getting too idealistic or romantic about accuracy/neutrality. Reality is something different.
We can't make assumptions that all recording/mastering/production gear is the same, all studio monitors sound the same, all engineers have perfect hearing, and any number of other variables that are influencing the production are consistent. We also can't assume that all music is produced to sound its best on the most accurate reproduction equipment, and that the final product is exactly what the artist intends.
Considering this, can we reproduce the music with true "fidelity"? And should we discount personal taste and enjoyment on the grounds of accuracy?

I think a product we can sell to audiophiles are jars of "audiophile air" that the drivers on the headphones can pump instead of Oxygen.

"Audio-Air will allow your headphones to perform to their full potential by replacing the dirty, dusty Oxygen air around you with lab-engineered and formulated air specifically designed for sensitive drivers to vibrate to, resulting in the most accurate reproduction of vibration and sound. Your ears will love you for it."

Use that to sell jars of nice smelling air. Rake in the moolah, yeah baby :cool:

And to the lazy ones amongst you: true neutrality to me is simply to reflect the recording accurately, which the O2 should do according to nwavguy.
That Isone Pro looks like its worth playing around with. I plugged it into foobar and my first impression on the default setting was "... its less warm" :p

They were intended as rhetorical questions.

A more practical example. What's technically more accurate, HD800 or MSpro? Most would say HD800.
If i owned only these 2 headphones, what would i be using? I'd say the MSpro 90% of the time or more.

Rereading your previous post I think I see what you mean by rhetorical. And BTW, I totally agree with you, none of my gear could be considered neutral; I like bass, what can I do? :cool:

However all I'm saying is that the amp (IMO) should just amplify what comes in without affecting the sound.

Yeah, let headphones do the sound production. The amp... Just give the headphones power and stop doing anything else :unibrow:

Don't forget the source. IMO, the DAC and the amp should be as noise free and neutral as possible. Flavour-fi should come from headphones :)

On the other hand, damn this plugin is sweet. I can't turn it off without feeling slightly queasy from the soundstage collapsing in ><

I don't disagree.

My point was more that (as much as possible) it makes more sense to aim for a neutral source and amp and let the headphones do the colouring. That way you don't have to worry so much about component matching, which people seem to use to try and neutralise things anyway (matching a warm source with a cool amp etc).

I already think it's borderline crazy that I keep different headphones for different music - matching other components in the chain as well seems flat out insane.

Nah haha, it's just simple and fun to experiment around with different colors and font types and see what works.

I'm currently studying Networking at Polytech West and just completed Certificate 4 few weeks ago, waiting for my cert to arrive in the mail :nod:

Here's another one:
