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.

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.

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!
