With all the current fuss about getting audio data from a computer to a standalone D/A processor via S/PDIF, USB, FireWire, WiFi, or Ethernet (footnote 1), it has been overlooked that the oldest way to get audio from a PC is to use a high-performance soundcard plugged into the host machine's motherboard. I remember how excited I was when I installed a Sound Blaster Pro 16 board in the 486-based Dell running Windows 3.1 that I was using in the early Clinton era, plugged its analog output into my high-end rig, and played back 16-bit/44.1kHz files.

I know, center-channel speakers are the bailiwick of our sister magazine Home Theater. But as Wilson Audio Specialties' Peter McGrath told me when he explained the speaker's technology to me in the Utah company's suite at the Mirage, two Polarises work magically as a stereo pair. (Unfortunately, the speaker was only being shown, not demonstrated.)

I had gone into the Koetsu USA room at the Venetian to catch up on the latest developments to the Italian Blacknote DSS30 media server, which I hope to be reviewing later in the year. But I was very taken by the sound of the three-way Odeon Elektra loudspeakers ($19,100/pair), which, driven either by the DSS30,a Goldennote Stibbert CD player, or a Montegiro LP player, via a Goldennote 75Wpc, solid-state integrated amplifier, didn't sound at all like what I expect from horn speakers. Strings had a natural sheen, brass winds a natural "blattiness." Whether solo voice, classical orchestral, or solo piano (a high-rez Beethoven Sonata from 2L), the sound was uncolored, unstrained, and enjoyable.

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.

Some products at CES—all-black products, with black highlights, and with the lettering tastefully done in black, in a darkened room—defeat all but the most-determined photographers. So my thanks to Larry Greenhill for managing to photograph the new Classé CTM600 600W monoblock amplifier ($6500 each).

"So what you think our new AT1 loudspeaker will cost?" Atlantic Technology's Peter Tribeman had just finished his dem of a fairly small two-way tower that, driven by Parasound Halo JC 2 preamplifier and Halo A21 power amplifier, was producing prodigious amounts of low frequencies in a fairly large room.

I was aware of CEntrance from the code they supply for the Texas Instruments USB receiver chip used by Benchmark , Bel Canto and others to allow USB connection without there having to be a driver program on the host PC. But the Chicago-based company also makes USB-based hardware, and at THE Show, Jason Serinus and I bumped into their Managing Director, Michael Goodman (left) who is showing Jason the cute DACport USB Headphone Amplifier ($500). This 24/96-capable, bus-powered, cigarette lighter-sized product has a miniature USB port on one end and a ¼" headphone jack on the other, with a small volume pot on top. CEntrance also makes similar bus-powered products with an A/D converter to connect microphones and electric guitars to a PC via USB.

The first night of CES saw a memorial reception held in honor of loudspeaker designer Jim Thiel, who passed away last September. A succession of high-end audio's greatest offered thoughts and reflections on a talented, well-respected, and universally liked man whom everyone agreed was taken from us too soon. Shown in my photo is erstwhile Stereophile publisher Larry Archibald, whose comments were deeply felt and moving. I paid my own tribute to Jim in my November 2009 "As We See It" essay, which I reprised in my closing day's speech at THE Show, discussed above by Jason Serinus..

I have come to expect innovative engineering from Rockport's Andy Payor, and was not disappointed by his new Alya loudspeaker. The two-way Alya costs $29,500/pair and marries Scanspeak's new beryllium-dome tweeter with a custom Audio-Technology woofer with a 6.5" carbon-fiber cone and a 2" voice-coil. The front baffle is aluminum and internal horizontal rods connect it to the rear of the cabinet, holding the HDF enclosure in a rigid grip. A rear port is tuned to a respectable 35Hz.

The Rockport Alya's 1.25"-thick front baffle is cast from aluminum, then machined to accommodate the drive-units. The tweeter's usual front-plate is discarded and replaced by the baffle, which has the necessary opening and locating pins. This gives a very clean acoustic environment for the dome. Andy Payor's hand is shown here locking the tweeter into place with a ring that screws into a thread tapped into the rear of the baffle.
