Thanks, @wormsdriver. I have ordered SR80e. I will definitely consider replacing the cable. Coincidentally I have ordered some supplies (Mogami and Canare cable, and some Switchcraft 3.5 mm plugs) to replace the cable on my SR125 woodies, so I will be stocked to tackle the SR80 as well.
You're going to like those Grados... They're "fun" in the best sense of the word. Before getting to the headband and cable, I would address the pads. I realized the difference pads make with my DT880s by switching to gels, but the Grados respond quite interestingly... Primarily in terms of comfort and wearability. Enjoy them, I started with SR60 for a week, the shot up to HF2.
