Scottmac - If you are in Seattle, as am I, I'm pretty sure Definitive carries a Grado and Senns....not positive though...I haven't been to Stereo Row in a long time.
32 Ohm has it all and great amps as well.
Here's a feature on them.
I use a
Woo Audio WA6SE maxxed-out. It's a very good pairing with the HD800's but I'd be willing to bet the Cary would be great too. Do you know how much power output the headphone jack has on that? The downside of the HD800's is that they really demand a good amp (again - though I have no direct experience to say for sure, I'd bet the Cary would be up to the task). I'm not sure that the Grado would be as demanding - It is certainly easier to drive. I've never heard the Naim headline and don't know anything about it. I assume it is SS since it is Naim. In general I've tended to prefer tube amps, but not as a rule. With the kind of investment you'd be making in one of those cans, I'd definitely take the time to compare them directly with the kind of music you like listening to and see which one floats your boat (or if either do). Being in this region, you have no excuse not to. There is a
headphone meet coming up very soon put on by Headfi.org members. I've been to one before, just a few months ago. They are a nice group of folks - very diverse, ... more so than the range of folks I've met via Audiogon. It may be worth your time to go check it out - you may hear some things you've never heard and really like. You can tell Gil I sent you. It's only about two weeks away. You don't have to bring anything at all with you - some folks come to listen and socialize. Most bring their headphone rigs, and there's all kinds of systems there. I'm sure there will be at least one HD800...probably a Beyer T1 too (another good candidate for fans of Rock who want the refinement and detail of a really good headphone). I did not see any Grados PS1000's at the last meet though. If you really want to listen to one find a dealer that has both like 32 Ohm.
