LATEST ADDITIONS

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.

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.

The Metrodome may have collapsed but Minneapolis-based Bel Canto sure hasn’t. Brand new at CES is the C5i, a DAC/integrated amp/headphone amp that sells for the feel-good price of $1895. The amplifier, said to be stable into 3 ohm loads, puts out 60Wpc into a 8 ohms. The amp also includes two S/PDIF digital inputs, a USB input capable of handling 24bits/96kHz data, a moving-magnet phono input, an RCA line input and a headphone amplifier. I marveled at this little gem’s price but also its sound as it played files from a nearby laptop driving a pair of Joseph Audio speakers. This was my first room of CES 2011 and it was a great start!

Also on display was Bel Canto’s new headphone amplifier (shown right), a product so new it doesn’t yet have a proper model number or name. Bel Canto’s John Stronczer let me take a listen to the amp through a pair of in-ear headphones. The sound was lovely, but I couldn’t really get the cans to stay in my ears (I must have very large ear canals).

When I checked out the back of the headphone amp I noticed that it was in the signal path of the room’s big rig. The DAC3.5VBS’s outputs went into the headphone amp and the outputs of the headphone amp went to the rig’s amplifiers. I asked John, “What gives?” He told me that he has been experimenting with using the new headphone amplifier as a unity gain buffer, taking advantage of the headphone amp’s ultra-low output impedance. John said that he hears improvements in the system using this configuration and that Bel Canto is exploring new applications for this technique. No price has yet been set for this headphone amplifier.
