I have compared both. (there are threads galore on this. check the archives) I went with the M20s. This was an easy decsion. They, for my ears, were better in almost every way. Do not go with their stands, though. They (the 805s, too) are poor and will have only a deleterious affect on your music. Read, (in the archives, too) my review of the Sistrum Mini Monitor support system. Have your M20s (or 805s, or Dynaudio 1.3s) sit on top of those babies and you'll freak. Trust your ears. I liked the M20s better than the Dynaudio 1.3s. Some like the 1.3s. Go with what makes your tympanics tingle. Good luck.
