It appears I'll have at most $120; this leaves me with either the Vali, E12, or Ocean. Because of the lack of specs on the Ocean, I'll probably go for one of the others. The E12 has been recommended to me by a good friend, and may be better for my low impedance Grados. I'll likely go with the E12, but I'll be doing some more research in the next couple days.
