Krell Evo 202:
Solid-state preamplifier. The 202 is a two-chassis design; the power supply, with its quad-rectified 170VA toroidal transformer and 39,600µF of filter capacitance, is housed in its own shielded chassis. The signal path is a zero-feedback, high-bandwidth, 1.5MHz open loop in a balanced Krell Current Mode design, terminating in Krell CAST (Current Audio Signal Transmission). Specifications: Input impedance: 45 ohms CAST (current mode operation), 95k ohms balanced, 47.5k ohms single-ended. Output impedance: >1M ohm CAST, 50 ohms balanced, 25 ohms single-ended. Gain: 12dB CAST or balanced, 6dB single-ended. Analog Inputs: (2) CAST (LEMO), (2) balanced (XLR), (3) single-ended (RCA), (1) tape loop (RCA). Analog Outputs: (2) CAST, (1) balanced, (1) single-ended and (1) tape.
Krell Evo 600:
Solid-state monoblock power amplifier. Krell employs an Active Cascode Topology to eliminate global negative feedback and CAST II current gain system in the signal path. The massive power supply (5000 VA) section features extensive electrical and magnetic shielding to keep radiated interference out of critical amplifier circuits. The 600 also sports internal high-current line-conditioning filters (remove AC noise and DC on the mains). With an open, liquid and effortless sound. Specifications: Output power: 600W pc into 8 ohms (27.8dBW), 1200W pc into 4 ohms (27.8dBW).
(3) Inputs: (1) CAST (current mode operation, LEMO), (1) balanced (XLR), (1) single-ended (RCA). (1) Output: 1 pair speaker binding post. Maximum output: 196V peak–peak, 69V RMS. Slew rate: 100V/µs. Input impedance: 70 ohms CAST, 200k ohms balanced, 100k ohms single-ended. Input sensitivity: 3.72mA CAST, 3.72 V RMS single-ended or balanced.. Voltage gain: 25.4dB. Maximum output current: 49A peak. Output impedance: >0.03 ohm, 20Hz–20kHz. Damping factor: >270, 20Hz–20kHz, ref. 8 ohms. Remarks: Retail prices when new: Krell Evo 202: €19.900 and Krell Evo 600: €33.900.
