Love music? Still want to spin those vinyl LPs to hear all the great music you’ve collected? If you listen to music regularly and don’t require the extra channels of a home theater receiver, put the Integrated 225 on your list of “must haves”. It’s an all-in-one Anthem quality two-channel analog solution that offers the performance of high-powered separates, without the associated cost and complexity. The Integrated 225 is an amplifier/preamplifier boasting a high-quality built-in phono stage to accommodate Moving Magnet phono cartridges.

As usual our “keep-it-simple” philosophy lies front and center. The Integrated 225 is sleek, its outlook minimalist. It doesn’t call attention to itself in any overt way yet when it sits in the A/V rack, you can’t help noticing just how good it looks. The inside story is similar: high-quality component parts; critical inputs are buffered to prevent crosstalk; a combination active/passive “EQ” technology in the phono stage unlocks all of the magic hidden in those vinyl grooves … with a transparency, refinement and detail that should be far more expensive, but isn’t.
