Some high-end audio companies develop reputations for having a particular "sound." This reputation develops when every product the company makes has a similar sonic flavor. These products appeal to certain customers who like the company's sound, and who therefore tend to stay with that company's products year after year. Unfortunately, such an approach can limit a manufacturer's appeal to a broader audience.

Perhaps I shouldn't have been surprised when I first spied the prototypes for Sonic Frontiers' luscious new digital combo, the Transport 3 CD transport and Processor 3 D/A processor, at HI-FI '97 in San Francisco. After all, this is the company whose meteoric rise from an electronic parts-supply outfit run out of president Chris Johnson's basement, to a large factory pumping out an impressive array of entry-level to <I>cr&#232;me de la cr&#232;me</I> tube electronic components, has elevated Sonic Frontiers to front-line status among high-end manufacturers.

The Jeff Rowland Design Group has long been renowned for the exquisite quality of its chassis. The company was one of the first to promote fully balanced topologies in preamplifiers and amplifiers in the high-end market, one of the first to offer a sonically acceptable remote control, and one of the few to offer a battery power option for their amplifier line.

Audio Artistry's Beethoven is the banner model of the company's Composer series (footnote 1), which includes the entry-level Vivaldi as well as the Dvorak I reviewed in the April 1996 <I>Stereophile</I> (Vol.19 No.4, p.204). Like the Dvorak, the Beethoven is a four-piece, bi-amplified, dynamic dipole design; unlike the Dvorak, the Beethoven has been taken to the <I>n</I>th degree of refinement.

Siegfried Linkwitz was born in Germany in 1935. He received his electrical engineering degree from Darmstadt Technical University prior to moving to California in 1961 to work for Hewlett-Packard. During his early years in the USA, he did postgraduate work at Stanford University. For over 30 years Mr. Linkwitz has developed electronic test equipment ranging from signal generators, to network and spectrum analyzers, to microwave sweepers and instrumentation for evaluating electromagnetic compatibility.
