Esoteric RZ-1 Music System

Havng recently used Esoteric's four-box SACD playback system, with its dual-mono DACs and the ultra-high-precision Rubidium Clock unit, I checked out what the Japanese company was displaying in the rooms they were sharing with cable manufacturer Synergistic Research. My eye was caught by this beautifully styled one-box SACD player/DAC/100Wpc amplifier. The RZ-1 is scheduled to sell for $6000 and as well as using one of Esoteric's highly regarded SACD/CD transport mechanisms, it has both 192kHz-capable S/PDIF and 24/96-capable USB digital inputs and—significantly for the way the audio market is going—a phono preamplifier. The 32-bit D/A section uses an AKM AK4392 chip and offers both a conventional reconstruction filter, one that resembles Meridian's minimum-phase "apodizing" filter.

As well as the RZ-1, Esoteric introduced the dual-mono D07 DAC at CES, which also offers the choice of digital filters as well as a digital-domain volume control. The D-07 will cost $4800.
