I agree with this question:
Having so many headphones with the reason to actually use them ( i know a guy who buys stuff with only reason to collect them) would drive me nuts honestly...
I prefer to get the best amp, best headphone, best source, best dac and best cabling my budget allows me instead of buying multiple headphones/amps with one reason only: to swap them to listen to...
Imho it would be a waste of money and lots of work getting every single headphone sounding on its best (upgrading cabling/finding right amp)
Dont get me wrong..i respect everyone having multiple amps/dacs/cables/headphones....but i just miss the point having multiple headphones except for collecting them ( or having different rigs on different locations ofcourse) and thats okay if u have the money for that
... Hope i didnt offend anyone now.
But damn..u have one heck of a nice collection!!! Respect! Did i just see my next baby? The he6? Lolz
And where is the sr007/009? Ur collection is not complete without one of those
