MOON 250i V2 Integrated Amplifier

MOON 250i v2 Integrated Amplifier

The MOON 250i v2 Integrated Amplifier is a classic, all-analog stereo integrated amp built for pure musical engagement—delivering 50 watts per channel into 8Ω (100W into 4Ω) with smooth authority, low noise, and wide bandwidth. A built-in MM (moving magnet) phono stage makes vinyl setup refreshingly simple, while six total inputs (including a front 1/8” mini-jack) keep everyday listening convenient without sacrificing audiophile priorities. Thoughtful engineering touches—like a rigid, vibration-minimizing chassis, precision-matched MOON bipolar output transistors, and a robust power supply—help it sound controlled, dynamic, and clean at real-world volumes. Add a front-panel 1/4” headphone output, variable pre-out for system expansion, and control options for custom installs, and the 250i v2 becomes an ideal integrated amplifier for serious Hi-Fi systems. The Moon 250i v2 is part of ListenUp's Moon Integrated Amplifier Collection.

What It’s Good At:

• Driving real speakers confidently with 50W/ch (8Ω) and 100W/ch (4Ω) stereo power for punchy, controlled playback.
• Making vinyl effortless thanks to the built-in MM phono stage for natural, precise turntable replay.
• Keeping an all-analog signal path for listeners who prefer external DACs/streamers and classic Hi-Fi simplicity.
• Headphone listening done right with a front 1/4” TRS headphone output and speaker-off option for private sessions.
• System growth-ready flexibility via a variable PRE OUT to add a power amp or expand the system later.
• Integration-friendly control with SimLink, IR input, and RS-232 for modern custom setups.

MOON 250i v2 Q&A:

How much power does the MOON 250i v2 deliver?

It outputs 50 watts per channel into 8Ω and 100 watts per channel into 4Ω, providing confident stereo control for many speaker types.

Does it include a phono stage for a turntable?

Yes—there’s a built-in MM (moving magnet) phono stage, so compatible turntables can connect directly for clean vinyl playback.

How many inputs are available, and is there a front input?

You get six total inputs: five rear RCA inputs plus a convenient front 1/8” mini-jack for a media player.

Can I listen with headphones?

Yes—the front panel includes a 1/4” TRS headphone output, and you can disable speaker output for private listening.

Can I use the 250i v2 as a preamp later in a larger system?

Yes—its variable “PRE OUT” lets you feed a separate power amplifier and use the 250i v2 as a preamp/control center.

Does it have custom-install control options?

It supports SimLink (in/out), an IR input, and RS-232 (DB9) for automation and system integration.

What power does it require, and what fuse does it use?

It’s specified for 120V/60Hz or 240V/50Hz. Fuse ratings: 4A fast blow (3AG) for 120V and 2A fast blow (3AG) for 230V.

What accessories come in the box?

Included are an AC power cable, CRM-3 remote + two CR-2032 batteries, a SimLink cable, the owner’s manual, and warranty/registration info (USA/Canada only).
