While I wait for my incoming ms-1i, back in the day, headfiers were pretty happy with the TTVJ flats. There were lots of Grado mods, but those were very popular more or less across the board for stock Grado/Alessandros. Times have changed though, maybe having something to do with the i updates, and I'm noticing lots more seem to be enjoying the bowls again, or revisiting the HD414 pads.
There are a gazillion threads about Grado pads, but no really updated nonscientific poll. What's your favorite pad of choice with a stock Grado or Alessandro and why? The reason I emphasize stock is that there are a billion and one mods for Grados, and each of those mods would impact which pads would be preferred. But we're kind of a democracy here, so if you have Grados that were left in stock form for about 30 seconds after you got them, and you feel like you gotta have a say, then have at.
Step forward all ye Grado lovers and ye shall be heard!
