Tested and wow, fabulous detail & sound stage, with a beautiful warm, but clear sound. Best suited to acoustic, jazz, & classical, where it really shines when matched with good efficient speakers. Hear sound & detail through this amp I've never heard before. Fabulous. Non-fatiguing. My go to non-rock. Well built & hansome to look at. Oozes quality in aesthetics with the wooden shell. ********************************************************* Power output: 40 watts per channel into 8Ω (stereo) Frequency response: 15Hz to 50kHz Total harmonic distortion: 0.05% Damping factor: 90 Input sensitivity: 2.5mV (MM), 150mV (line) Signal to noise ratio: 64dB (MM), 83dB (line) Semiconductors: 27 x transistors, 8 x diodes, 2 x zener diodes, 1 x led Dimensions: 440 x 160 x 225mm Weight: 7kg
