After extensive development, we are happy to announce the availability of a new solid-state amplifier from Audio Research that combines high efficiency, musical sound and ample power - all at a very affordable price. The new 15.2 combines the groundbreaking Class T digital switching technology first used in the 150M multichannel amplifier with a fixed (non-modular) two-channel design in a package sized like the older 100.2 amplifier.
The 150.2 produces a strong 150 WPC into 8 ohms, and 300 WPC into 4 ohms. BAL and SE inputs are provided, along with a 12V trigger and detachable A.C. power cord. Like the 150M, the 150.2 produces very little heat because of its high efficiency, so it is ideal for in-cabinet installations. Handles are optional at additional cost, as on the 150M. Musically, the 150.2 is very much like the remarkable 150M - very refined, open and natural. Some have described the 150M as having virtually no coloration of its own, so that it presents the source material with remarkable transparency and purity. We think the 150.2 is very similar in character, and is sure to find compatibility with a wide variety of loudspeaker types. This amplifies really sings with any Audio Research preamp! The 150.2 is sure to create a secure, popular niche for itself in the Audio Research product line. It is an entry-level power amplifier with pedigreed performance and the stature of the Audio Research name.
