I'm 28 years old and I live in a small village near Amersfoort, the Netherlands.
I grew up in an audiophile family where my dad was always saving up for the next upgrade to his equipment / cabling / speakers. As such, I got bitten by the hifi bug in my early teens and stayed with it ever since.
However, it wasn't until a year ago that I discovered the world of headphone hi-fi.
I started a year ago with a set of Sennheiser 558's, bought a FiiO E12 for them and rockboxed my iPod. A couple of months ago I also purchased a pair of Momentums and today I became the proud owner of a Little Dot Mark III (my first tube amp ever). I'm currently saving up for an upgrade from the 558's (650?). As you can see, Head-Fi has already made a significant dent in my wallet.
Thanks for all the info you all have provided already. I'm looking forward to learning even more from all of you in the future.
