Few topics will get audiophiles into an argument more readily than a discussion of the relative merits of tubed and solid-state equipment. A poll on the Stereophile website showed 53% of respondents choosing solid-state as their preferred amplifier design, while 38% indicated a preference for tubes—the remainder choosing "other," which presumably means digital amplifiers. (There has been no corresponding survey regarding preamplifier designs.) Opinions tend toward the dogmatic, with one respondent declaring "solid-state is more accurate," another stating unequivocally that "tubes sound closer to the real thing."

Last week, Asahi Kasei Microsystems Semiconductor (AKM), which supplies audio ICs for professional and consumer products, announced its line of Direct Stream Digital (DSD) Digital-to-Analog converters capable of supporting both Super Audio CD (SACD) Direct-Stream Bigital and 24-bit/192kHz LPCM DVD-Audio formats.

As John Atkinson puts it, Meridian usually does things "their way," putting amps and DACs inside of speakers in an all-out attempt at "re-creating the original soundfield, no matter how many speakers and channels it takes to do it right." But as Atkinson finds, the Meridian 518 Digital Audio Processor might be the company's most perverse product: "The $1650 518 offers digital inputs and outputs only. It can digitally perform gain and source selection; it can change data with one digital word length to data with another; and it does all these things with 72-bit internal precision." So JA asks, "How does the 518 fit within a conventional high-end audio system?" Read along as he figures it all out.
