Any one here using the Bel Canto EVo 200.4 amp and or PRe1 ?

Please share with me your user experience with either or both of these components. Based on reviews these look like my next upgrade. No dealers even close to my area, so no inhome audition. Do you use the 200.4 as biamp or bridged power? What interconnects , power cords speaker wires have sounded good with these components? What speakers are you using and how big is your room? Please help. These look so promising, but only an owner would know for sure. Thanks!
