I'm very new to this, but already really interested in this kind of gear, so you can count me in too. London has got be the location. I'm 100 miles away, but it's always great to have a good excuse for a visit to the capital. My recent purchases: Hifiman HE400, Beyerdynamic 770, and a Hifiman EF 2A. Older gear I had been using - up till now, Grado SR 60, Sennheiser HD595 and HD280. Output, a cheap DAC and a really cheap valve headphone amp from Hong Kong called little bear. Great little bit of kit though (it's featured in my profile pic). Main interest for me is to be even more wowed by great sounding gear and give me a reason to aspire to (read as, save for) even better kit. Main reason for using this equipment - I write music and work it through right to the final mix - all on headphones!
