Rather a mouthful, the name of this digital decoder is derived from that of the designer, Robert Wadia Moses. The "computer" part of the title relates to the custom digital filter function generated by a set of 32-bit microprocessors: for simplicity's sake, I shall abbreviate the name to "WD1000." A more expensive version, called the '2000, sells for $6995, and carries some additional features and details. The resampling rate is increased to 64x in the '2000, with the additional optical and digital input switching and the main power supplies each contained in separate additional enclosures.
Editor's Introduction: Stereophile's "Recommended Components" feature is, as I am sure you will have guessed, produced by a committee. The reviews are studied, the reviewers polled to verify the continued validity, the merits and demerits of specific pieces of equipment are discussed or, rather, argued over at length by JGH, JA, and LA, and out of the whole business emerges the "truth." But, as with the findings of any committee, what is presented as a consensus will have significant undertows and countercurrents of opinion; if these are very strong, a "Minority Report" is often also produced. Such has been the case this time, concerning loudspeakers.
It's been five years since David Wilson's X-1/Grand SLAMM speaker system invaded our audio consciousness with its 500W power capacity and very high (95dB/W) sensitivity (footnote 1). Capable of an earsplitting 123dB at 1m, with a bandwidth to match, this was one speaker system that refused to be ignored. The X-1 has since evolved to $70,000/pair Mk.II form. It now provides some flexibility of tonal balance for different room acoustics, and is distinguished by greater subtlety in its differentiation of timbre. Beneath the X-1 in Wilson's range comes the WATT/Puppy ensemble, now in its 5.1 iteration (footnote 2). The WATT/Puppy has survived for over 10 years, and sets a benchmark for the Wilson line at its $17,270 system price.
"Where do you want 'em?" Doug'n'David (of Stereophile's shipping and receiving, not your favorite morning drive-time talk radio co-hosts) had just wrestled over 500 lbs of cocooned Wilson WITT loudspeakers onto the floor of my garage. Like the Thiel CS7s I had parted with just a few weeks earlier, the WITTs came packed in solid, heavy wooden crates. The pained expressions on Doug'n'David's faces indicated that it was time for me to start reviewing minimonitors! The unpacking went more smoothly than I expected, but this is clearly a pair of loudspeakers that demand to be delivered, uncrated, and set up by a dealer.
How can a reviewer possibly put a value on a loudspeaker as costly as the Wilson Audio Specialties X-1/Grand SLAMM? When he reviewed Wilson's WATT 3/Puppy 2 system ($12,900-$16,000/pair, depending on finish) a few years back (footnote 1), John Atkinson said that it was "one of the more expensive loudspeakers around." The Grand SLAMM costs almost five times as much!
A committed audio equipment reviewer operates at the front line of audio subjectivity. Working on behalf of a readership made up of consumers thirsting for independent, informed opinion and advice, a reviewer is commissioned by the editor of a magazine to produce reports with a technical and subjective content on a wide range of available audio products. These reviews must be both fair and completed at short notice on a relatively small budget.
