Positive features:1. Heavy duty power connectors with dual terminal option on both the positive and the negative terminals. The dual terminal function consists of a screw type for a wire lug or Allen set screw for stranded number 4 wire. This feature can also be used to connect a large external capacitor to the power terminals.2. Heavy duty speaker terminals with Allen set screw for number 8 stranded wire (although number 10 wire seemed to fit with a lot more ease).3. Quasi-differential input for low noise and elimination of possible ground loops (a must with a four-channel amp).4. -12 dB sensitivity switch for high and low level input (high level 600MV-8.5Volts) (low level 150 MV-2 volts)5. Extra crossover section for auxiliary output. 6. Passed reactive load test.7. Cosmetically a great looking amp.8. Fan cooling
Negative features:1. Chassis is a little on the big size for a 400 watt category.2. Low channel separation (50 dB ) 3. Higher THD with all channels driven.09% vs...033% (single channel)
Comments:Very slight turn-off tick.
