CES 2012

For several years now, the CES's High-Performance Audio exhibits have been housed at the tony Venetian Hotel on the Las Vegas Strip. And also for several years, the room shared by Stereophile and Home Theater magazines, now joined by our sister websites AudioStream.com and InnerFidelity.com, has been hosted by our administrative assistant (which means she is the glue that holds us together and tells me she prefers to be called our "Digital Goddess") Rosemarie Torcivia. Welcome to Las Vegas, Ro'.

Checking out the Reference 3A speakers (Grand Veena, MM de Capo i, etc.) in Divergent Technologies' room at T.H.E. Show, I noticed that the center of the midrange and mid-bass drivers looked different. Divergent's Tash Goka was not in the room, but the person who was there introduced himself as the one responsible for the modification of these drivers. He's Ricky Schultz, inventor of the Surreal Acoustic Driver Lens, a small plastic device that is glued to the drive's dustcap, and has the effect of broadening the dispersion. The Surreal Acoustic Driver Lens is being incorporated into the production of all Reference 3A speakers. It's an OEM product, not available to consumers, and, according to Schultz, it has the potential to improve the performance of many loudspeaker drivers. He proceeded to provide me with the explanation of how the device works, but it quickly went over my head.

Shown above is the new Pandora DAC which has three slots on the back for a variety of input options including AES, USB (asynch) and SPDIF, and tube analog stage and both balanced and unbalanced outputs and an optional volume control. Retail is $6k.

Stephen Mejias has written about Anssi Hyvönen of Amphion, who believes that music reproduction doesn't have to be loud to be effective, and that, in fact, the hallmark of a really good speaker is its ability to be involving at low levels. Amphion's demos always provide for a soothing experience at shows, and so it was at CES 2012, this time using the new Argon7Ls ($5999/pair) with Nuforce electronics.

UK manufacturer Astin Trew had their new DAC 1 on display. Managing Director Michael Osborn was on hand to answer questions and look for US distribution for his products. The DAC 1 features asynch 24/192 USB as well as FireWire and I2S inputs. It has a 6922 buffered tube output stage for single-ended connections and solid state for balanced output. Price should be around $4,500-$5,000 and would arrive in about 2 months once distribution is set up.

The Audio Power Labs exhibit took my breath away, Imagine, a huge, beautiful $175,000 per pair, 200Wpc monoblock tube amplifier using 833C, graphite-plate, radio-frequency transmitter tubes that have a bandwidth of 30MHz and run with 1500V on the plates! These tubes were used in the output stage of BCF-1 radio transmitters. Now imagine that the amplifier's designers are named Squeek Rieker (right) and Peeya Iwagoshi (left), and you know why I had to pinch myself to make sure I wasn't dreaming.

Audio Research's Chris Ossanna proudly shows off the company's new $25,000/pair, two-chassis Reference 250 monoblocks, which employ the new KT-120 output tube. This amplifier has 50% more power-supply capacitance than their previous flagship, the Reference Anniversary 110, and uses the same type of Teflon coupling capacitors they sourced for their Reference Anniversary preamplifier. The front panel metering allows the consumer to check the bias and to adjust the speed of their response to either fast or slow.
