I have been using 4060s>MPS6030 for a while now (the 6030 is the same as the 6020 but has an 1/8" out instead of RCAs). Usually, mic-in and occasionally line-in when the music is really loud. This has worked very well for me, but, as fmaderjr pointed out, the 4061 is a lot less sensitive than the 4060. You might have to add a pretty good amount of gain from the recorder, depending on what you are recording...
