CES 2011

I first encountered the glass-enclosured Force dipole loudspeaker from Perfect Eight, which combines a full-length ribbon with 8 cone midrange units and a subwoofer handling the load below 60Hz, at the 2008 CES. Their 2011 dem, with the speakers driven by Ypsilon amplification, was noteworthy for having invited Ray Kimber to talk about and play some of his IsoMike recordings. (Ray is seen here on the left in my admittedly rather grainy photo—it was dark—with Perfect Eight's Jons Rantila.) I listened first to soloists from the Academy of St. Martin-in-the Fields performing a movement from the Mendelssohn Octet, then to a Mozart piano sonata movement by Robert Silverman (the latter one of my "Records to Die For" in the February 2011 issue). Despite my skepticism about glass as an enclosure material, the sound was natural and uncolored.

Rega's new 24bit/192kHz DAC has the full complement of inputs including USB (running at 16/44) and either Toslink or Coax SPDIF. But what sets it apart at its $995 price point is the pair of Wolfson WM8742 parallel-connected DACs used in a similar configuration to the company's $9,000 Isis CD player.

The DAC also has five front panel selectable filter settings including an apsodizing filter typically found on more expensive DACs. The DAC is shipping now and comes in silver or black.

Rega’s RP-1 record player ($450, plus $195 for the upgrade package which includes Rega’s improved drive belt, a thicker wool platter mat, and Bias 2 phono cartridge), replaces the popular P1 and features a new, hand-assembled RB101 tonearm, a lightweight phenolic resin platter, and a low-vibration motor. Seen here in titanium finish, the RP-1 is also available in gray or white. I’ve been using the RP-1 in my home system, and I’ve come to the conclusion that this no-nonsense turntable plays records like it means it. More to come in the February and March 2011 issues of Stereophile.

“What’s new?” is the question that comes up first with established manufacturers when considering whether there’s something worthy of a blog item. In Polk Audio’s case, the answer was “Everything!” According to Polk rep, Jim Crowley, their entire home audio line has been revamped, with changes in the cabinetry, drivers, and crossovers. Perhaps the most significant change is that now, for the first time, some Polk speakers feature a midrange driver. And with all that, Polk loudspeakers continue to be reasonably priced: the pictured LSiM is a modest-by-audiophile-standards $4000/pair.

Pride of place in the Avatar Acoustics room at the Venetian went to the four-way Siena speakers ($24,995/pair) from Italian manufacturer Rosso Fiorentino. The designer teaches electroacoustics in Florence, but is a graduate from the University of Salford in the UK. A pair of aluminum-cone 8" woofers in a separate sealed enclosure are combined with a 6.5" paper-cone midrange unit (a ScanSpeak Revelator), a 1" silk-dome tweeter, and what appeared to be a Murata "ultrasonic generator," to give a specified response of 35Hz–100kHz, –3dB.

The Siennas were demmed in a system comprising Dr. Feikert turntable and tonearm, Abbingdon Music Research CD player, phono preamp, and integrated amplifier, with Acoustic System racks and cables, but I will hand over to Jason Serinus for some additional thoughts:

Bob Deutsch, Kal Rubinson, and Jason Serinus awed by an appetizer at Origin India.

Although Sennheiser has come out with nothing that surpasses their wonderful, state-of-the-art HD 800 headphones, they have released three new, far less expensive audiophile models: the HD 598 most prominent in the photo ($329.95), the HD 558 ($229.95), and the HD 518 ($169.95).

I auditioned the HD 598, whose beige soft velour pads contrast elegantly with their black body. The salesperson who showed me around made a big deal of the packaging. Far more important were the frequency range, 15Hz–28kHz, and the sound. Although the rather bombastic source material was supposedly MP3, the headphones delivered impressively smooth bass and a far more natural-sounding presentation than I would have expected.
