MOON 250i V2 Integrated Amplifier, Silver/Black

The MOON 250i V2 is a purely analogue stereo integrated amplifier from Simaudio with a built-in MM phono stage, delivering 50 watts per channel and designed as the compact heart of a hi-fi system.

Why the MOON 250i V2?

Because it focuses on the essentials: the shortest, cleanest possible path from source signal to output stage, with no digital detours whatsoever. On paper, 50 watts sounds modest, but thanks to a current-stable circuit and a high damping factor it feels like a lot more – at 4 ohms, output doubles to 100 watts. An MM phono stage is already built in, plus four line inputs for CD players, streamers and more. That makes the 250i V2 the complete control centre of your analogue chain.

What you hear

A transparent, calm sound with tight bass control and a precisely drawn soundstage. The 250i V2 doesn't colour the sound and doesn't push itself forward – it passes the music on exactly as it was recorded. Thanks to its current delivery, it also drives more demanding speakers confidently and without harshness.

Who is the 250i V2 for – and who is it not for?

Ideal for anyone looking for an honest, purely analogue amplifier with a phono input – a long-lasting base that can always be extended with an external DAC or streamer.

Honest take: if you expect streaming, a DAC and app control in one chassis, this isn't for you – the 250i V2 is deliberately purely analogue. In that case, a streaming amplifier like the MOON Ace is worth a look. And for very large, power-hungry speakers in big rooms, a few extra watts wouldn't hurt.

Our verdict

A timeless, uncomplicated integrated amplifier that makes MOON's virtues affordable: purely analogue, clean, controlled – and with phono on board. With its silver side panels, it adds a bright accent to the rack. We at HD Zürisee in Wädenswil will tell you honestly whether its 50 watts suit your speakers and your room.

What the trade press says

Frequently asked questions

Are the MOON 250i V2's 50 watts enough?
For most living rooms and speakers, yes. Thanks to its current-stable circuit it delivers 100 watts at 4 ohms and confidently controls even more demanding speakers. We only recommend more power for very large rooms or power-hungry speakers.

Does the 250i V2 have a phono input?
Yes, an MM phono stage is built in. You can connect a turntable with a moving magnet cartridge directly, without a separate phono preamplifier.

Can I connect a streamer or CD player?
Yes. Besides the phono input, four line inputs are available – enough for CD players, streamers and other sources. For streaming, simply add an external streamer or DAC.

Why buy the MOON 250i V2 at HD Zürisee?
Because an amplifier only comes into its own with the right speakers. We match the 250i V2 to your room and your speakers, set up your turntable and sources, and as an authorised MOON dealer in Wädenswil we're here for warranty and service – with our own technician.
