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 Musical Fidelity M6si500 is rated at 500 watts RMS into 8-ohms.
Here are the main highlights of its performance specs:

Need more power?
Musical Fidelity M6si500 is rated at 500 watts into 8 ohms, which puts it in our Over 180 watts band. That is the top band we cover, so there is no step up from here - if it is not enough, the answer is more sensitive speakers or a smaller room, not more watts.
When pairing the Musical Fidelity M6si500 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 Musical Fidelity M6si500 Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the Musical Fidelity M6si500 amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:

Bluetooth Connectivity
Musical Fidelity M6si500 doesn't have bluetooth connectivity feature. In order to stream your music via bluetooth, the easiest way is to connect an external bluetooth receiver to your Musical Fidelity M6si500. Two bluetooth receivers that we recommend are the
iFi Zen Blue V2 and the
Audioengine B1.
Among the amps in the same price range, these are the 5 amps that have Bluetooth Connectivity:
Phono Input
Musical Fidelity M6si500 doesn't have a phono input so in order to play your vinyl albums, Musical Fidelity M6si500 has to be paired with a Phono Preamp that is MM (Moving Magnet) or/and MC (Moving COil) depending on your cartridge type.
Balanced connections
Musical Fidelity M6si500 has a balanced XLR input. A balanced cable carries the signal twice, on two conductors of opposite polarity. Interference picked up along the way lands on both equally and cancels when the two are recombined at the far end, so the longer the cable run and the noisier the surroundings, the more the connection is worth. Whether a balanced connection also yields more power depends on how the amplifier is built inside - some are balanced end to end, others convert to single-ended internally and deliver the same power either way, so it is worth reading the maker's own wording rather than assuming.
Musical Fidelity M6si500 Pros and Cons
Drawn from the published figures on this page, not from listening.
- ✓500 watts per channel into 8 ohms is more than most rooms and most speakers will ever ask for.
- ✓Dual-mono construction, with the two channels kept separate through the power supply.
- ✓4 analogue inputs, enough for a full rack of sources.
- ✓Home-theatre bypass, so it can join a surround system without fighting it for volume control.
- ✓Balanced XLR inputs, worth having on a long cable run.
- ✗Analogue inputs only - a TV, computer or CD transport needs an external DAC.
- ✗No Bluetooth and no network streaming - everything arrives over a cable.
- ✗It weighs 29.9kg - check the shelf, and plan on a second pair of hands.
