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 MOON 250i v2 is rated at 50 watts RMS into 8-ohms. MOON provides this wattage at a THD (Total Harmonic Distortion) of 0.02% which is an important indicator of distortion at the given values (lower THD is better).

Here are the main highlights of its performance specs:

  • 50 watts into 8-ohms (10 Hz-100 kHz) at 0.02%
  • 100 watts into 4-ohms
  • 4-ohms Min Impedance (allows compatibility with a wide range of loudspeakers)
  • 101dB Signal to Noise Ratio

Which speakers suit the MOON 250i v2?

50 W into 8 ohms, 100 W into 4, rated down to 4 ohms. We rank every passive speaker we cover against it on power, impedance safety and current delivery.

We check power, impedance safety and current delivery — not just watts.

When pairing the MOON 250i v2 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 MOON 250i v2 Amplifier good for?

An essential deciding factor is the size of the room in which you intend to employ the MOON 250i v2 amplifier. Here, taking into account its maximum power parameters, we analyzed its applicability to various size environments:

Frequently Asked Questions about MOON 250i v2

How much power does the MOON 250i v2 have?

The MOON 250i v2 delivers 50 watts x 2 channels into 8 ohms and 100 watts x 2 channels into 4 ohms. Its output almost doubles into 4 ohms, which points to a strong power supply that can hold its composure with demanding, low-impedance speakers.

Does the MOON 250i v2 use vacuum tubes?

No. The MOON 250i v2 is a solid-state amplifier - there are no vacuum tubes in it.

What amplifier class is the MOON 250i v2?

The MOON 250i v2 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 MOON 250i v2 have a built-in DAC?

No. The MOON 250i v2 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 MOON 250i v2?

Yes. The MOON 250i v2 has a built-in phono stage for MM cartridges, so a turntable can be connected directly without a separate phono preamp. It is voiced for moving-magnet cartridges; a moving-coil cartridge would need an extra step-up stage.

Does the MOON 250i v2 have Bluetooth?

No. The MOON 250i v2 does not have Bluetooth built in; you would need an external Bluetooth receiver connected to one of its inputs.

Does the MOON 250i v2 have a headphone output?

Yes. The MOON 250i v2 has a Yes-inch headphone output on the front panel for private listening.

How much does the MOON 250i v2 cost?

The MOON 250i v2 has a manufacturer's list price (MSRP) of $2,400.
