I've had my PCM-M10 for about a month now and I can't figure out how to make it sound as good as my MZ-M100. I bought it thinking it would sound as good with the ease of transferring files to my computer. I don't know if it's the built in eq on the M100 but I don't think so, I'm using the same mic with both and the normal sound setting sounds better on the M100. I hate having to use Sonic Stage but I haven't figured out how to beat the sound of my minidisk. If I can't find a fix I Think I might sell the M10.
