So many things in this world are designed for convenience, not for excellence. That's all right if you have a choice, but it becomes a problem when products designed for convenience become universal standards and are thus foisted on everyone—including enthusiasts, who must then live with a product aimed at the lowest common denominator.

The digital interface between CD transports and digital processors is a perfect example of this dilemma. The Sony/Philips Digital Interface Format (S/PDIF) standard was designed so that connecting two digital products required only one cable. This single cable carries left and right audio channels as well as the timing clock essential to making the system work.

The name "Audio Research" will be familiar to many readers of this magazine. It belongs on the list of that select group of manufacturers who continue to offer the audiophile and music lover equipment which enables him or her to truly enjoy the muse. With equipment of this caliber, one is no longer caught up in the anxiety-inducing process of listening to (evaluating) the equipment used in the presentation of the music. Instead, the listener can focus attention on the much more important message uncovered in the music via the performance and conveyed through the network of transducers, cables, tubes or FETs, more cables, more tubes or FETs, and more transducers, to the brain. If this process has been successful and our sensitivities heightened, our souls will be touched.
