I demoed them both very recently and brought the 805s. The spendors are very good but im my opinion were overpriced and once i managed to find an exdem pair of the 805S it was a no brainer for me. The vocals, bass, soundstage pretty much every thing were way better on the 805S. Just my experience. I listened to both on an cyrus mono x set up (closest thing i could think of to my bel canto stuff).
