The Sutherland Insight is a fine AC powered phono stage. We were able to show this at RMAF 2012 with the VPI Traveler turntable and Shelter 501II cartridge and boy did that combo sound great! The Insight finesses Sutherland's accumulated expertise into an exciting new option. The Insight is a self-contained stereo phono preamp with built in shielded power supply compartment. Dual mono board layout gives each channel the expected same circuitry. Going beyond that, an identical layout gives each channel the same physical environment. All the nuances of channel tracking are meticulously maintained. Not only is parts quality at the highest level, every aspect is harmoniously focused into an artist expression of beautiful design. The Insight delivers on both pride of ownership and musicality. All at a level well beyond its US retail price of $1,400.
