The Michi S5 is a dual-monoblock stereo power amplifier delivering 500 watts per channel into 8 ohms and over 800 watts per channel into 4 ohms. Each channel draws from its own custom-engineered, oversized, in-house manufactured 2,200 VA toroidal transformer, feeding a total of 188,000 microfarads of bulk storage capacitance split across four British-made capacitor banks.
Thirty-two high-current output transistors and a damping factor of 350 give the S5 the reserve current and control needed for large, demanding loudspeakers. Balanced XLR and unbalanced RCA inputs are provided, and the elegant aluminium chassis carries a front-panel display consistent with the rest of the Michi range.

Why Consider the Michi S5
The dual-monoblock construction is the point of the S5: each channel has its own transformer, its own capacitor bank and its own output stage, so demanding bass in one channel cannot draw down the supply feeding the other. At 500 watts into 8 ohms and nearly double that into 4 ohms, it is built for large rooms and loudspeakers that most amplifiers would struggle to control at volume.
Ideal For
- Large rooms with power-hungry floorstanding loudspeakers
- Pairing with the Michi P5 or Prestige P430 preamplifier
- Systems needing independent per-channel power reserves
- Loudspeakers with demanding, low-impedance bass sections
