Performance Specs
One of the most important factors when deciding on an integrated amplifier is its power ratings and compatibility with your speaker's impedance requirements.The Michi S5 is rated at 580 watts RMS into 8-ohms. Michi provides this wattage at a THD (Total Harmonic Distortion) of 0.008% which is an important indicator of distortion at the given values (lower THD is better).
Here are the main highlights of its performance specs:
- 580 watts into 8-ohms (10 Hz-100 kHz) at 0.008%
- 800 watts into 4-ohms
- 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
- 120dB Signal to Noise Ratio

Wiring more than one pair of speakers to it? Check the load first →
Which speakers suit the Michi S5?
580 W into 8 ohms, 800 W into 4, rated down to 4 ohms.
We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
When pairing the Michi S5 with a passive Bookshelf (Stand mount) or Passive Floor Standing (Tower) speaker, you have to check if their Max Power Range is below the max wattage of the amp for the given impedance levels.
Operating your amp outside of this max range may damage the speakers.
What size of room is the Michi S5 Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the Michi S5 amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:

How much power does the Michi S5 have?
The Michi S5 delivers 580 watts x 2 channels into 8 ohms (FTC). Rotel also quotes 500 watts continuous into 8 ohms and 800 watts into 4 ohms, and Michi leads its marketing with the 500 figure. It increases its output into 4 ohms, so it has some headroom for harder-to-drive speakers.
Does the Michi S5 use vacuum tubes?
No. The Michi S5 is a solid-state amplifier - there are no vacuum tubes in it.
What amplifier class is the Michi S5?
The Michi S5 uses a Class A/B amplifier design. Class A/B is the traditional linear design: it runs warmer and is less efficient than Class D, but it is long valued for its natural, low-distortion sound.
Does the Michi S5 have a built-in DAC?
No. The Michi S5 has no built-in DAC, so a digital source such as a streamer or CD transport needs its own converter, or you connect it over analogue.
Can I connect a turntable to the Michi S5?
No. The Michi S5 has no phono input, so a turntable needs an external phono preamp (or a deck with one built in) before it can be connected.
Does the Michi S5 have Bluetooth?
No. The Michi S5 does not have Bluetooth built in; you would need an external Bluetooth receiver connected to one of its inputs.
Does the Michi S5 have a headphone output?
No. The Michi S5 does not have a headphone output, so headphone listening needs a separate headphone amplifier.
How much does the Michi S5 cost?
The Michi S5 has a manufacturer's list price (MSRP) of $9,499.
