Fewer among us are aware that the upper limit of sound quality an audio system can deliver will be established by whichever audio contraption we use to select our sources and adjust their volume.

As much as I delight in pagan dreams of sweetly perfumed garden nymphs, I'm embarrassed to admit that my mind also drifts in pleasant reveries whenever I hear the words research and development in the same sentence.
