In answer to how I arrived at the Raven Nighthawk 1) Made in USA 2) Crazy good reviews 3) Total upgrade value within year (Or immediate refund) Primaluna, Leben, and Line Magnetic are made overseas. NOW I know that the personal service from Raven Audio in Texas is way above and beyond anything I've ever experienced from any dealer or audio manufacturer. These guys at Raven really care and help on a level which is simply unbelievable. Klipsch heritage line are hyper sensitive. When I first hooked everything up I had hum. My router, phone, and modem were are way too close to the amp. Once moved all was well. The tech called me to talk about the situation. Offered to ship back. Since then the owner Raven Dave has helped me get tubes, James has called, Bryant calls...Do Raven....these LaScala are totally blowing me away. (No subs necessary any more) Paul Klipsch would be proud....my Mullard preamp tubes up front are truly miraculous. Thanks Raven Dave....
