As far as I'm cocerned my GS1000s eat my old modded Sennheiser hd650s and even my AKG K701 for breakfast; they are more open, detailed and have better soundstaging than any of the former. Sibilance? Have you tried changing your mains cables and distribution? It can help. Also Grados take some running in and the ones tried could be rather new and bright.
