I have to agree with you. While it would be nice to have an astronomically expensive music system, headphones are a nice, and most of all, cheaper alternative. I'm a bit of a newbie when it comes to cans, only because I am limited by my pockets; I have read countless reviews and opinions on music and sound theory, but I never thought I would own more than one "nice" pair of headphones. I currently own Beyerdynamic's DT 770 Pro LE, as well as their DT990 Pro 250 ohm. I also have a set of Sennheiser Momentum Bowie limited edition I won in a giveaway. I drive them with a Fiio E17 Aspen DAC/amp. Eventually I want to get a set of Planar Magnetic headphones, but for now, these "will do". Music wise, I have a 160GB iPod Classic with about 32,000 songs in an assortment of bit rates as well as two backups on external hard drives. I also procure vinyl, which I listen through an AudioTechnica LP120-USB. Realistically, the vinyl is for nostalgia; the collection of music, is the hoarder in me; I find myself using Spotify more than I'd like to admit for the convenience.
I also have the dt770s, and I'm quite jealous of your other equipment. How do you like the fiio amp? A decent dac/amp is next on my list but I'm having a hard time finding something because I want one capable of also powering speakers and a turntable (at the same time) when I eventually get them. The headphones in the picture are a planar set and if you like the dt770s, I would strongly recommend them. The amount of added depth and detail is insane, but they still have the kick to them that open headphones sometimes lack. Yeah, when I bought my first "nice" headphones, the V-Moda M80s, I didn't think I would need any more. In fact, I recall saying "they're expensive, but I can use these for the rest of my life." Little did I know...
