Anthem Integrated 225 Features
Construction quality of the 225 is excellent. The front panel is fabricated from 3/8" thick aluminum and even the machine screws that fasten the steel cover to the chassis are flush with the surface. I removed the cover to have a look at the inside of the amp and all circuitry is neatly organized and logically laid out.
The Integrated 225 amplifier is a Class A-B design with six bipolar devices per channel. Its generous power output of 225 watts per channel uses a torodial transformer backed by dual 30,000 micro-farad filter capacitors, which provides plenty of dynamic headroom and makes it well suited for a wide variety of loudspeakers, even those with a sensitivity spec well below 90dB.
The Anthem amp uses analog circuitry throughout, even employing a motorized analog volume control that can be controlled manually, by remote control or via the RS-232 control interface for use with a system controller. A lighted indicator on the volume control would be helpful since there is no on-screen or front panel display to indicate volume level.
Custom installation features include a +12-volt trigger in-out connection so it can activate other components or be activated by a control system. Its detachable IEC power cord makes installation easier.
The moving magnet phono stage uses active and passive equalization that, according to Anthem strictly follows RIAA standards and is designed to provide accurate, uncolored reproduction of vinyl recordings. High-output moving coil cartridges can also be used with the Integrated 225.
There are a few features I wish the Anthem amp had, including a separate headphone level control, a pre-main coupler and bass management circuitry for use with a subwoofer.
Most notable was Diana Krall's breathy, sultry voice in How Insensitive in her "From This Moment On" disc. Every breath had a palpable in-room quality that makes this great recording sound live. Her voice was easy to visualize as it floated between the speakers. Each musical element was distinct and the soundstage sounded almost three-dimensional as if I were listening to a multichannel recording. Bass was full and warm from the moment the track began with the bass drum.
Percussion instruments sounded distinct and tight from Diana Krall's piano to the dual guitars in Acoustic Alchemy's Mr. Chow. Cymbals were crisp, clean and detailed without the sonic smear so common in busy recordings with multiple musical instruments.
A good recording brings out the best in a system and Ana Caram's "Anos Dourados" and Sara K's "Miles Away" from Chesky Records was no exception. Every minute instrumental and vocal detail sounded meticulous and precise.
Ah, the warm sound of a vinyl recording. My carefully preserved LPs sounded as good as ever on the Integrated 225. Joan Baez' "Diamonds and Rust and Quadrophenia by The Who were just a few of my favorites I listened to on the Anthem amp.
