I used to own a Wadia 850 and regretfully sold it because I got caught up in the Audio Aero hype and just had to buy a Capitole 24/192. Huge disappointment overall, I must say. I know I'm going to get some hackles up, but that's the way it is. It just put me to sleep, no involvement in the music. Smooth, yes. Good for unobtrusive background listening, especially on female vocals, absolutely. Involving, no. Able to shine on a wide variety of music, 'fraid not. And the build quality, downright scary, especially when coming straight from an 850. I currently own an 830 and am happy again. Neutral, musical, and natural dynamics. Not as good as the 850, but close enough to live with for now. I'm saving up for an 861, but I've heard a lot of good things about the 301 and I don't doubt them.
