I've spent six-odd years in a sort of hi-fi counterculture, playing with things like mono cartridges, one-box CD players, and cheap, homemade cables&mdash;and, of course, owning and listening to single-ended triode (SET) amplifiers and horn loudspeakers. But before all that, I owned components that, while more mainstream, did the job just as well in certain ways. That category included solid-state electronics (Naim, BEL, Spectral), dynamic loudspeakers of middling efficiency (ProAc, Epos, Magneplanar), electrostatic loudspeakers of very low efficiency (Stax), and even "high-end" accessories like Tiptoes and <A HREF="http://www.stereophile.com//features/69/">Shun Mook Mpingo discs</A> (which I still have, although my five-year-old daughter has more or less permanently co-opted the latter for playtime use).

Being a metallurgical engineer, I've always been intrigued by audio cables&mdash;their construction, the materials they're made of, how they're produced, and, of course, how all of that relates to their sound. Over the years, I've auditioned a wide range of cables, from Nordost's round conductors in a flat cable, to Alpha-Core's flat cables in a round conductor, to MIT's complex termination systems. I've even got a closet full of cables&mdash;some quite good&mdash;from companies that no longer exist.

There may be hope for the most common type of hearing loss. Researchers at the University of Michigan have succeeded in growing new hair cells in the inner ears of laboratory animals, the first time that such cells have been regenerated in mammals.
