Description
400W 8 ohms per channel stereo amplifier with a large 5000VA power supply. So powerful that it uses a 20 amp power cable AND an industrial circuit breaker as a power switch to match its 5000VA internal power supply. Active cascode topology eliminates global negative feedback, only nested local feedback around individual gain blocks is used. The result is a remarkably open, accurate and light sound.
The signal path includes Krell Current Mode and CAST circuits using proprietary multi-output current mirrors in a complementary and balanced arrangement for outstanding open-loop linearity.
The Evolution circuit topology breaks through the bandwidth limitations of conventional designs resulting in near-perfect performance in the audible range.
