Anthem Integrated 225

Anthem Integrated 225

Pre-owned, in excellent condition.

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 with all Anthem components, the Integrated 225 boasts all parts of high quality and close tolerance, including metal film resistors and high-quality film signal capacitors. The result is the lowest possible total harmonic distortion plus noise. To prevent one source from interfering with another, critical inputs are individually buffered.

With a 105 dB signal-to-noise ratio, the Integrated 225 rivals the achievements of more expensive separates. Anthem’s always meticulous attention was paid to ground planes and the design of the power supply (see section on Power Supply). Circuit board traces were laid out by hand. From a rich and silent black background, the only thing the audiophile is aware of is the music—rich and refined, full and enveloping, leaving you to wonder why anyone would contemplate spending more.

Designed specifically to accommodate today’s high-quality Moving Magnet phono cartridges, the Integrated 225’s built-in phono stage will delight even the most die-hard vinyl enthusiast.

Since the job of the phono stage is to supply most of the gain, two factors are critical in achieving the highest level of playback quality: a superior approach to RIAA equalization and the quality of amplification used to step-up cartridge output to line-level voltage.

The integrated 225’s main power supply boasts an advanced generation toroidal transformer, a major contributor to the low-noise floor. This massive transformer is conservatively rated and designed with high rail voltage. It feeds two oversized (51 mm x 80 mm) low-ESL, low-ESR Nichicon filter capacitors employing a total capacitance of 30,000 microfarads. The main power supply also features ±15 V rails for the preamp audio circuits fed by two precision voltage regulators.

Input and voltage amplifier stages are a differential design, output power stage is a fully symmetrical complementary Class AB design with three pair of high-quality bipolar output devices per channel. Designed to dramatically reduce distortion, this arrangement also ensures extreme linearity, effortless response and extensive bandwidth while minimizing power consumption.

The Integrated 225 features a large motorized analog potentiometer style volume control which tracks exceptionally well, rivaling the performance of a stepped attenuator. Volume can be adjusted three ways: manually, or with the remote control, or through the RS-232 interface.

The Integrated 225’s robust binding posts ensure full and uninterrupted power delivery to the loudspeakers at all times. They’re very easy to use and will facilitate large speaker cable connections. In addition to these speaker outputs, the Integrated 225 also includes Pre-out (for possible bi-amping applications) and Rec-out line level outputs.

The Integrated 225’s trigger feature allows the unit to be turned on or off remotely via a trigger from another component or control system. The 3.5 mm (.125 in) mini-jack input receives a 12 V signal from the upstream component or system controller. The same trigger signal can be linked to other components through the trigger output.

A handy portable media input plus seven more stereo audio inputs include: Phono, CD, Balanced, AUX 1, AUX 2, AUX 3, and Recorder (Tape In). Each input can be connected via pairs of RCA connectors on the back panel of the Integrated 225, with two exceptions. The Balanced Input consists of two XLR connectors on the back panel and a portable media input is a 3.5 mm stereo jack and selector located on the front panel for quick and easy access. Any one of the inputs can be selected by pressing the appropriate button via the front panel, remote control or RS-232 command.

XLR balanced connections are common in both professional recording studios and broadcasting to ensure the lowest level of noise and hum. Now you can use this same high-quality connection since the Integrated 225 includes an XLR balanced input. Gold-plated female RCA jacks on this unit also provide high quality single-ended input connections.
