The Michi S5 is a formidable flagship stereo power amplifier from Rotel, built with staggering output power and an exceptional damping factor. The Michi S5 represents Rotel's most ambitious current statement in stereo power amplifier engineering.
Key specs that matter
Input sensitivity is 4.2mV via XLR or 2.6mV via RCA. Input impedance is a substantial 100,000 ohms balanced or 12,500 ohms single-ended. Output power is a substantial 500W into 8 ohms, rising to a staggering 800W into 4 ohms. Gain is 24dBu balanced or 28dBu unbalanced. Frequency response spans 20Hz to 20,000Hz within plus-or-minus 3dB. Total harmonic distortion plus noise is under an exceptionally low 0.008% at 100% global feedback. Damping factor is an exceptional 350. At 485 x 238 x 465mm and 59.9kg, the Michi S5 represents Rotel's absolute current flagship power-amplifier engineering ambition.
Sound and use context
Expect extraordinary dynamic authority and control reflecting the staggering 800W-into-4-ohms output combined with the exceptional 350 damping factor, representing Rotel's most accomplished current engineering ambition.
Pairing
The staggering 800W into 4 ohms output handles the most demanding loudspeaker loads with substantial headroom to spare.
Alternatives
Rotel's own RB-1590 offers a somewhat more accessible alternative within the same broader power amplifier catalogue.
