LATEST ADDITIONS

One of my more pleasant duties at this year’s CES was substituting for John Atkinson at a dinner for the press held by DTS. (JA had not arrived yet from New York.) What I was particularly looking forward to—in addition to dinner at Nobu, one of Las Vegas’ best Japanese restaurants—was the opportunity to meet the legendary “JJ”: James Johnston (left), audio researcher, who has been called “the father of perceptual coding” for his work while at Bell Labs on MP3 and MP4. JJ is Chief Scientist at DTS, and also a Forum contributor at stereophile.com, occasionally jousting with those who make claims about sound reproduction that he feels have no scientific basis.

The pre-dinner presentation dealt with the latest surround sound format from DTS: Neo X 11.1, which uses 11 channels. Yes, folks, that’s 11 speakers, 11 channels of amplification, plus a powered subwoofer. There is not definite word on exactly when software and consumer hardware for this format will be available, and DTS admits that an 11.1 channel system is not something the average consumer will likely aspire to. However, a point made by JJ was that even if DTS 11.1 does not reach broad consumer acceptance, the research on 11.1 will lead to a better implementation of surround sound with 5.1 or 7.1 systems. He made an allusion to some work that he’s doing now—which he could not discuss—that promises sonic virtual reality with a lot fewer than 11 channels.

I did get to meet and chat with JJ, and found him to be very genial—not at all like the doesn’t-suffer-fools-gladly persona that’s sometimes in his Forum postings.

Jim Fosgate’s forthcoming Signature headphone amplifier (right), scheduled for release in the second quarter of 2011, has an industrial design that echoes his Signature phono stage (left). Combining a tube input stage with a solid-state output, it will include a loudness control, spatial enhancement circuit, and built-in DAC. Scheduled for distribution by Musical Surroundings of glorious Oakland, CA, its price has yet to be determined.

Conrad-Johnson introduced their new ET5 line stage preamplifier. According Bill Conrad and Lew Johnson, the ET5 is a scaled-down version of the GAT preamp (the silk-screening you see here labeling the ET5 as a GAT is an error). The ET5 shares all of the same parts as the GAT but is a stereo design instead of the GAT’s dual-mono layout. The ET5 uses Vishay resistors, CJD Teflon capacitors, gold plated OFC I/O connectors and vibration-isolated printed circuit boards for the gain circuit. The ET5 ships this month and will cost $9500.

The Stello Ai500 integrated amplifier was shown in the April Music room. A 150Wpc integrated with a built-in high resolution DAC, the Ai500 sells for $3500 and ably drove power-hungry Magnepan speakers.

Audio Power Labs was a new name to me, and not without reason. The company was recently started up by a number of audio enthusiasts, including a number of ham radio operators and this was their first showing at a CES. The 833TNT monoblock amplifiers (price not set) use an interesting compliment of tubes, including two 833C tubes that are often used in small AM transmitters and a switching power supply.

Sony has a track record of sporadically producing high-quality loudspeakers, like the SS-M9 that I reviewed in 1997. But as good as these speakers could be, their commercial success was limited. But at the last two Rocky Mountain Audio Fests, Ray Kimber had been getting great sound with a prototype Sony floorstander and the 2011 CES saw the official launch of the Sony SS-AR1 ($27,000/pair).

A three-way design, the SS-AR1 uses Scanspeak drive-units made to Sony's specification, housed in a unique, Japanese-made enclosure. Seen here standing next the basic enclosure, designer Yuki Sugiaro explained that the walls are made from Finnish birch ply and the front baffle from maple ply. The latter is sourced from trees grown in Hokkaido.) The woodworking is so precise that the cabinet shown here is holding itself together without any glue (thoigh glue, of course, is used on the production line).

Driven by Pass Labs amps and an EMM SACD player, the SS-AR1s were demmed in too small and crowded a room for me to pronounce on their sound quality, other than to note that the midrange seemed exceptionally clean and uncolored. But my prior experience at RMAF suggests that this will be a contender.

Availability is said to be "spring" and Sony announced that they have already signed up blue-chip US dealers like Goodwins, Definitive, David Lewis, and Music Lovers.

Sonneteer, a UK audio company, was showing off its new Morpheus Music Center ($4000), an integrated amplifier, DAC, and control center for streaming audio. The amplifier section is rated at 50Wpc and will stream music via WiFi or Ethernet, play Internet radio, and USB input. The Morpheus also has three analog inputs and one analog output so it can send signal to an external power amplifier or subwoofer. Standing by his creation is Sonneteer’s Haider Bahrani.
