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 Naim Nait 5si is rated at 60 watts RMS into 8-ohms.
Here are the main highlights of its performance specs:

We rank every passive speaker we cover against it on power, impedance safety and current
delivery.
Need more power?
Naim Nait 5si is rated at 60 watts into 8 ohms, which puts it in our Up to 60 watts band. The next band up is 61 to 90 watts, which is worth about 3.9dB more output. That is a real difference in headroom on peaks, and a modest one in how loud the system plays - power and loudness are not the same thing.
Before buying watts, check what your speakers actually need: the amp and speaker matcher works it out from their sensitivity, impedance and your room.
When pairing the Naim Nait 5si 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 Naim Nait 5si Amplifier good for?
An essential deciding factor is the size of the room in which you intend to employ the Naim Nait 5si amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:

Bluetooth Connectivity
Naim Nait 5si 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 Naim Nait 5si. 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
Naim Nait 5si doesn't have a phono input so in order to play your vinyl albums, Naim Nait 5si has to be paired with a Phono Preamp that is MM (Moving Magnet) or/and MC (Moving COil) depending on your cartridge type.
Naim Nait 5si Pros and Cons
Drawn from the published figures on this page, not from listening.
