Sorry for the delayed reply.
I've been doing a bit more intensive listening with my SR-60s, trying the original comfies (thanks, F107plus5!) as versus the replacements from Radio-Shack, and running through a wide variety of music. I've come to a couple of conclusions:
- I don't know what I'm doing. Unfortunately the limit of my high-end headphone experience ends with my beginner 'phones. It seems that I'm in need of personally hearing any upgrades, if at all possible. Might someone know of a place (or person!) I could see to do so in the Stillwater, MN region (or Twin Cities, etc., though the closer to Stillwater the better
), I'd be much obliged.
- It's becoming increasingly apparent that I've caught the bug, as more listening time with even these beginner Grados has caused me to determine that I need to re-rip my albums at no less than 320kbps, remove equalization and sound enhancers, and pursue the headphone equivalent (or better, as will probably be the case) of my Yamaha tower speakers. While I haven't taken a liking to the Sennheiser sound from the few sets I've heard, I have quite the desire to sample the higher-end Grados, the Beyerdynamic line, AKGs, and so on. I really was satisfied with my SR-60s... I had no idea that they'd actually cause a need for better headphones through simply listening. Ah well, there are certainly worse money-sinks.
I also think I'll pick-up some bowls for my SR-60s if I don't end up purchasing a higher-end set of Grados. I think they might bring me closer to the sound I've been looking for out of them. The rumors are certainly true, though it has taken me months of listening to discover for myself: Grados seem to be very dependent on their pads and, in turn, the distance and angle to your ears. We'll see!
