Well, I have a little headphone spending to do, and I'm looking for a direction to travel. I'm planning with a budget of around $600, and the way I see it, I have two general options. But I have decided that I want to make some sort of Grado purchase. A) I've wanted a set of Grado woodies for quite a number of years. And with that budget, I can get a new set of RS-2i, or a very good used set of RS-1 or RS-1i. I'm also interested in the HF-2, even though they're not wood phones. So, that'll be one purchase, which will easily be my most expensive set of cans ever. B) I could downgrade my Grado purchase to something like the 325is, and leave half of my budget available for an additional headphone purchase. If I were to do this, I would get something from a manufacturer I've never purchased from before. The idea being, I would then expand my audio "pallete", so to speak. I'd then consider options, used or new, for companies like Denon, Beyerdynamic, AKG, or Ultrasone. The only good set of phones I currently own are HD25s, so I don't have a collection to draw from, to learn more about the sound I like. I know I love the HD25 sound, but I have a hard time explaining why. After this purchase, I'll be taking a break from buying phone, and start saving for better amplification. So, do I get the best single pair of phones I can afford, or do I spread it around? Which do you think I'll appreciate most, in the long run?
