CES 2011

Pass Labs showed off two nice beer fridges, er, amplifiers at this year’s CES. Lacking any model numbers or nomenclature, the top monoblock amp (the top two units) is a single-ended 200W amp ($45,000/pair) and the bottom monoblock is a single-ended 300W amp ($75,000/pair). Nelson Pass is shooting to use no feedback on these circuits and maintain the Super Symmetry design made popular in far less extreme applications. The new part for these amps is a brand new silicon-carbide FET. These FETs were initially designed for the military—way to turn swords into plow shares and space heaters, Nelson!—and Pass Labs intends on exploring their use in future products.

Bluebird Music's Jay Rein wanted to hear the Bluetooth-driven Chordette Gem-based system at the front of the room, with Spendor A6 speakers, but my attention was drawn to the familiar-looking speakers at the other end of the room, Peak Consult El Diablo Vs ($89,000/pair), which Michael Fremer reviewed in May 2007. Jay explained that he is ow the North American distributor for these Danish speakers.

The speakers were being driven by Chord SPM1400 monoblocks ($$32,900/pair) and a Chord CPS5000 preamp, with van den Hul's new Mountain interconnects and Nova speaker cables. Jay put the Reference Recordings CD of Scheherazade (RR-89CD) with Jose Serebrier conducting the London Philharmonic Orchestra into the Chord Red Reference Mk,II CD player ($25,900) and for an all-too-brief interlude, I was transported from the fake glitz of Las Vegas into the more real sonic world of the Arabian Nights.

Polk’s Blackstone TL3 ($300/pair) marks the eight-generation of Polk’s satellite speaker systems, and combines prior Polk technologies with new industrial design and improved time-aligned drive units, including a ring-radiator tweeter. The system we heard included a Marantz receiver and Samsung Blu-ray player, and I was very impressed by the small speakers’ ability to throw a wide soundstage with solid center-fill and fine detail.

John Atkinson readies the awards which will be picked up by the winners throughout the day.

PSB’s new Imagine mini ($700/pair) is available in five attractive finishes and uses a 1” tweeter and 4” clay/ceramic-filled polypropylene cone mid-woofer. The speaker measures approximately 5.75” x 9.5” x 8.3”, has high-quality, gold-plated five-way binding posts, and can be mounted on any hard surface or used on traditional speaker stands. Playing with NAD’s C565BEE CD player ($799), C165BEE preamp ($899), and C275BEE amplifier ($1199), the sound of acoustic guitars was enchanting and commanding, with fine detail, impact, and emotion. Very impressive.

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.

Here is a close-up of the Qsonix iPad app that offered real-time scrolling through album covers in addition to the playlist editing.
