You could say there are two lines of sight towards the same objective in audio amplification. The hifi industry has chosen one route by and large- increasingly high powered amps, often in the hundreds or thousands of watts, coupled with low efficiency loudspeakers. The OMA way is entirely different. We created Parallax PL519 as a low power single ended amp to be used with high efficiency loudspeakers. The result of this combination is a truly startling level of naturalness, detail, and ease. None of these qualities are usually associated with audio equipment today.
