In recent years the model has been recognized with numerous awards in many international hi-fi magazines and many testers today refer to the device as a “reference”. The claim is therefore fully justified that the AMP II is one of the world’s best output amplifiers in its class.

The German magazine “STEREO” rated the AMP II as a reference output stage and awarded the product the maximum points.

“…an output stage for high quality music, suitable for universal use and compatible to all loudspeakers. […] And clearly an inside tip for music lovers as this is the first time it has been possible to upgrade to the class of the top references for output stages for such a reasonable price.

The sound of the Accustic Arts amp immediately characterized itself with a sharply focused soundstage, a smooth-sounding midrange and upper frequencies, and a general lack of veiling across the musical spectrum. The Amp II-ACHP came across as sounding honest. Its presentation was balanced — no aspect of its sound stood out. In fact, you might initially have a hard time identifying a sonic fingerprint from which to identify it. This is usually a good sign, and oftentimes is one indicator of long-term satisfaction.The increased-capacity power supply helps the Amp II-ACHP deliver a rated 240Wpc into 8 ohms, 400Wpc into 4, and a whopping 600Wpc into 2 ohms. The output stage consists of 24 MOSFET transistors, 12 per channel, while filter capacitance is specified as 160,000 microfarads. Comprehensive protection circuitry guards against clipping, high-frequency oscillation, and excessive DC offset.

The bottom line is that Accustic Arts and the Amp II-AC High Performance are real players in an industry populated with fine-sounding amplifiers. The Amp II-ACHP casts a sharply defined soundstage while producing a balanced, clear view into the music. It’s also a powerhouse of an amp. This “Big Beauty” may prove a popular alternative to the usual suspects if its list of strengths is attractive to your audiophile sensibilities.
