HYBRID STEREO AMPLIFIER


Developed as the mate to our award-winning PRE 1L and PRE 2L preamplifiers, the AMP 2 combines an all new hybrid design with a robust, regulated power supply, sophisticated circuit topology, conservative operating parameters and efficient industrial design practices, into one uncompromising, yet affordable, stereo power amplifier product. The sonic result is an amplifier which is both fast and tonally neutral, with the real power and control to adequately drive even the most demanding speakers.

Introducing ANTHEM's newest & most powerful amplifier - a high power hybrid design combining the musicality and finesse of vacuum tubes, with the solidity and control of solid-state. This next generation product is uniquely capable of providing music enthusiasts with extremely high value, and unprecedented sonic performance, which successfully merges the strengths of both technologies.

DESIGN FEATURES:
- Hybrid design
- Two tube input stage (mil-spec 6922's)
- Solid-state driver stage
- Bi-polar transistor output stage (Motorola devices)
- >200 watts/ch into 8 ohms; >300 watts/ch into 4 ohms
- Bridgeable into mono (over 600 watts)
- 1.2kVA toroidal power transformer

TECHNICAL OVERVIEW: This 31dB gain design is comprised of 4 stages. First, a vacuum tube buffer and phase splitter are used to provide a high input impedance as well phase inversion for bridged mono configuration. Next, a constant current sourced, double differential cascode input stage topology was chosen due to its better balance between both halves of the input stage, how it aids in power supply ripple rejection and because of its excellent CMRR - all of which combine to offer a very linear design, before feedback. Third, a high current, Class A transconductance/driver stage was chosen because of its drive capability and excellent slew characteristics. Lastly, this is coupled to a cascode configured bipolar output stage, utilizing 12 Motorola 150 watt devices per channel. Overall, this amp has an unusually low amount of negative feedback due to its intrinsic linearity and inherently low distortion open loop characteristics.

Why settle for a product which compromises one sonic aspect for the other? You can have the best of both worlds with ANTHEM's next generation products... a sublime combination of both power and finesse which audiophile music lovers have long been searching for, at a price never before thought possible!
