I seldom replace or upgrade items from my hobbies. I have however sold/upgraded a few headphones already in under a year, and plan on at least one more upgrade ( see below ) in 2010, while keeping most of my existing inventory. In 2010 I plan to buy the following: D7000 ( sooooo looking forward to these!) K702 ( why debate HD650 vs. K702 when I can have them both and keep each for their strengths vs the other ) SR225i (which I will upgrade and sell my SR60i for.) I will also be buying an LD DAC later in that year...and possibly a set of DT 880 600 ohms. I may also ( money permitting ) buy a SS amp of some kind. We'll see. Guess I will have to moonlight and start dancing around that stainless pole to help fund these babies. Anyone thinking of their 2010 purchases yet??
