yes I can confirm the problem is fixed, I used to have skips every minute or so on lossless (mine is 32gig), after loading the new 2.2.1, problem is gone. now I finally can use it as my main source.

since you are looking into the mid range, I shall recommend the SCL4 from shure, they are actully the old e4c/e4g, I compared them with er-4p and the se530, driven by the RSA p51, I like SCL4 the best out of the 3, sweetest mids ever!
