Sound Quality First

Monoblock design for perfect channel isolation and exceptional sound quality.

Designed first and foremost to sound superb in all types of audio systems with all types of music.

Low noise, low distortion, wideband amplifier design with traditional Class A/B output stage ensures smooth, detailed sound, without a trace of strain or harshness.

Totally stable with real world speakers in real systems; not just on a test bench.

Modern Efficient Circuit Design

Optimized Soft-Switch Class H™ power supply topology delivers improved efficiency without compromising audio performance.

Switched Mode Power Supply (SMPS) offers all of the performance of a traditional linear power supply, with improved efficiency and reliability, and reduced overall weight.

Quality Construction

Top quality parts and construction throughout for years of reliable trouble-free service.

Heavy steel chassis with milled aluminum faceplate offers strength and rugged good looks.

Solid machined gold-plated RCA input connectors provide a reliable connection with a wide variety of audio interconnects.

Designed, assembled, and tested in the U.S.A. at our plant here in Franklin, Tennessee.

Flexible Signal Connections and Power Options

Audiophile quality gold plated five-way speaker binding posts allow you to use a wide range of speaker cables with bare wires, lugs, or banana plugs.

Choice of balanced or unbalanced inputs, controlled by a reliable metal toggle switch.

Remote trigger input and output allow the XPA HC-1 to control and be controlled by other trigger-enabled equipment.

World compliant AC line voltage operation enables the XPA HC-1 to operate on any line voltage between 100 VAC and 250 VAC 50/60Hz.

Standard IEC power inlet fits all standard IEC power cables and most custom audiophile power cables.

Protection

Audiophile-grade fault protection is entirely transparent under normal listening conditions, yet protects the amp and your other equipment from virtually all common faults.

The XPA HC-1 is protected from AC line faults by a rugged resettable rear panel push-button circuit breaker.

Full five-year warranty ensures that you’ll be able to enjoy your XPA HC-1 monoblocks for years to come.

The power amplifier performs the simple but critical job of boosting the output signals from each channel of your stereo preamp or surround sound processor to the level necessary to drive your loudspeakers. While this may seem trivial, a really good power amp is essential to having a great audio system, because any flaws in the performance of your power amp are going to limit the performance of your entire system. Every amplifier in the new Third Generation XPA series was carefully designed to deliver superb technical performance, unsurpassed sound quality, and an exceptionally accurate and dynamic rendition of all types of music, thus ensuring that your entire system will sound its absolute best. Each individual XPA amplifier is modular, and can be customized to provide exactly the power and number of channels you need today, and expanded later if your needs change; and multiple matching chassis enables you to add even more channels, or more power, for a nearly endless variety of options.

Circuit Topology

The XPA HC-1 is a monoblock audio power amplifier, with a fully discrete, dual differential, high current, short signal path Class A/B amplifier section, Optimized Class H™ power supply topology, and microprocessor-controlled fault protection.

The XPA HC-1 is powered by a high efficiency, audiophile grade, Switch Mode Power Supply (SMPS).
