Yeah, I sort of got the same impression... that the refs are a bit tired of handling inquiries about the ESW11LTD.
Anyhow, I think the ESW9 pads would suffice. Its performance is tested and true to my ears, and the ESW11LTD pads are quite different, so I'm afraid it may again change the sound.
So far I have tried 4 different ear pads on the ES10 (stock, ESW9, aftermarket leather, aftermarket velour), and all of them change the sound in one way or another. I don't doubt that the ESW11LTD pads would also sound different, and I'm not sure if I'll like it any more different. I think the ESW9 pads are perfect... for all intents and purposes.
