With the show spread out between a half dozen hotels, and Las Vegas one of the most inefficient cities to move around in, it's tough to see everything. I simply ran out of time before getting over to the Bellagio to see Olive, but Kal Rubinson was able to make it one morning.

His photo above shows the company's new O6HD which is described as a "music server for audiophiles". On top is a modest 10.1" touch screen and inside is a fully balanced differential DAC design that can run at 24bit/192kHz. There is also a headphone jack and slot for ripping discs under the lip on the front. Internal storage is 2TB and it has both balanced and unbalanced analog outputs in addition to HDMI, USB, Ethernet and WiFi which supports the free iPad/iPhone apps. Price is $4,999.

At the Venetian, Avatar Acoustics' Darren Censullo set up several of the products he distributes including the Purist HDR 6D music server/DAC from AMI HiFi. Darren explains that there are seven versions of the HDR 6D and 6DA, depending on how it is configured, ranging in price from $2,500 to $25,000.

On the front is a slot for loading or playing music from discs and a clever flush-mount receptacle for putting your iPod Touch which then acts as a touch controller and display. There is also a free iPad app.

All the usual inputs and outputs are included: AES/EBU, SPDIF, USB, Ethernet, WiFi and HDMI which supports a full video player. The HDR 6D handles a wide variety of file formats up to 32bit/384kHz (on the 6DA) and the company says that sound quality is enhanced by a process that entirely caches each track for playback. Also included is upsampled Web Radio and multi-room playback.

An iPod Touch (you must supply your own) embedded in the face plate.

Famed audio designer/engineer Demian Martin, known for his work with Spectral Audio, Constellation and others, is also part of Auraliti, who were displaying their wares at T.H.E Show in the Flamingo.

Shown above is the heart of their new product line, the L1000 File Player, which is controlled by either a wireless iPhone/iPad type device or networked web browser and runs Linux. The company says there are no moving parts in the L1000 which boots from a Solid State Drive and has an AES/EBU output for connecting to your DAC. The L1000 Outputs up to 24 bit/192kHz and can handle FLAC, WAF and AIFF files. Price is around $3,000.

Fang Bian has long been a maker satiating the desires of headphone enthusiasts. Head-Direct's line-up of products includes many headphones including the orthodynamic headphone HE-6 ($1199), headphone amplifiers, and seemingly the only portable music players that could be legitimately called high-end. The HM-801 ($790) looks and feels a bit cumbersome, but the electronic goodness of the Burr-Brown PCM1704 DAC chip and OPA627 op-amps, and the ability to play back 24bit/96kHz FLAC and 16bit/44.1kHz FLAC, WAV, APE, OGG, WMV, and MP3 files will make your portable listening a real treat.

So, as if his headphone activities over the past decade or so isn’t a career enough, he’s also been going to school and a few months ago received his doctorate in nano-technologies. Wow! I wouldn’t be surprised to see a HiFiMAN player ten years hence in a pill. Twenty minutes after you swallow it you can hear a CD by rubbing it between your hands. :-)

Congratulations Dr. Fang Bian, on both your academic and sonic successes!

For a decade or more, I’ve begged Japanese company Audio-Technica to bring more of their domestic models into the US. Woot! Seems like they’re doing it. The recent addition of the ATH-A900 (closed back; $249), ATH-AD900 (open back; $299), and the beautifully finished Black Cherry wood of the ATH-W1000x Grandioso (closed back; $699) will broaden choices for the strong following among headphone enthusiast who prefer a tastefully done fast and airy sound.

I know you guys have more stuff over there . . . if you’re listening, bring it on.

Steven Hill, designer and owner of Straight Wire, has released his new Expressivo line of speaker cable ($700/8 ft pair). The cables, which contain four conductors surrounded by multiple spiral shields, include a compressed conductor of special OFHC certified copper and a spiral polyethylene rod that encapsulates the conductor. The net result of his geometry is that the spiral rod only touches the conductor group in a small area, resulting in an effective air-spaced dielectric.

Hill claims that Expressivo’s soundstaging, imagery, and detail retrieval surpass those of his Maestro speaker cable. Expressivo occupies the middle of Straight Wire’s loudspeaker cable line, with three lines above it. The company’s full range of cables ranges in price $1/foot to $150/foot for speaker cable, and from $15 to $900/1m pair of interconnects.

Cable manufacturer Kubala_Sosna has been in business eight years, with business expanding each year. This year, the company’s products were in use in 12 rooms at CES.

Just introduced are two new digital cables, the Emotion S/PDIF ($1500/first meter, $300/each additional meter) and Elation S/PDIF ($2700/first meter, $400/each additional meter). Both cables are a step up from Kubala-Sosna’s previous Expression level.

“We’re raising the bar, no doubt,” said keen recordist Joe Kubala (pictured on the right). In perfect agreement was partner Howard Sosna (left), who designs the cables in collaboration with Joe.

With the new cables used to connect the PS Audio Perfect Wave Transport to the Perfect Wave DAC, I heard impressive bass and captivating warmth coming through the not-too-shabby Tenor Audio Reference 350M monoblocks ($100,000/pair) and Estelon Model XA loudspeakers ($43,900/pair) from Alfred & Partners in Estonia. Of course it helped that Estelon’s entire line is internally wired with Kubala-Sosna.

Derived from Finite Elemente’s Emperor rack, the Soundbase equipment shelf ($1800) is filled with aluminum foam whose random patterning allows it to absorb energy and dissipate it as heat. Immedia’s Stirling Trayle notes that the shelf works as well for turntables as for other components.

Each Soundbase comes complete with four Cerabase Slimline coupling feet that use a combination of three internal ceramic ball bearings and stainless steel for ultra-efficient energy transfer. The Cerabase Slimlines are also sold separately for use under components ($550/set of four). Their three internal ceramic balls represent an advance in “resonance deflection” technology for the company.

“Go check out the Constellation Audio room,” said Jon Iverson. So I did. As I entered the room filled with unworldly looking gear I spied Michael Fremer, engrossed in one of his famous mix CDs, burned from his vast vinyl collection. Michael, ever the gentleman, relinquished the sweet spot to me and both of us took in some big, clean, transparent sound. Driving a pair of $150,000 Tidal speakers was Constellation’s Hercules amplifiers ($70,000 each), which are each able to put out a kilowatt of juice into 8 ohms and runs its first 250W in class-A.

The visual design of the amps is both striking and understated, clad in an all aluminum chassis. Each side of the amp has a diffuser grid which hides the amp’s heatsinks and allows for a chimney action to help cool the amplifier. All that aluminum also serves the purpose of mass-loading the amps to control vibration. Internally the amps mechanically float the sensitive signal carrying parts. That attention to vibration damping could be heard as stillness and ease, particularly when I played a high-resolution file of Robert Silverman playing the final fugue from Brahms’ Variations on a Theme by Handel. My time in the Constellation room was stellar.
