I too had the Nautilus 805's as well as an HTM-1. While I always loved listening to them and I never had a problem with them, the first time I heard the JMlab speakers I knew I had to make the change. I sold all my B&W stuff and got a pair of JMlab Electra 906's and an Electra 901CC. My new JMlab stuff, to me sounds better in everyway as compared to my old 805's. I just wish I could have afforded to go with the Mini-Utopia, cause that was even better, of course like you said it should be for the extra cost. The 906's run at 2k a pair while the Mini-Utopia's run at 7k a pair. Interesting note, the magazine Absolute Sound is going to be putting up the Electra 906's as there speaker of the year in one of their upcoming magazines.
