CES 2013

The earth's ecology may be upside down, but Kevin Deal of Upscale Audio displayed PrimaLuna's new DiaLogue Premium integrated amplifier ($3299) that way for a positive reason. "It has a laundry list of the best parts," he declared, handing me a sheet that touts oxygen-free continuous-crystal copper, silver-plated, Teflon-dielectric point-to-point wiring; Takman audiophile grade resistors, and SRC tinfoil capacitors in critical signal paths; and an Alps potentiometer. The DiaLogue Premium is claimed to have such a good auto-biasing mechanism that you can mix and match 6L6GC/KT66, EL-34/KT77, 6550/KT88, and KT120 power tubes in any combination or permutation you so choose, and a bad tube indicator in case your sonic Devil's Brew won't cut it on the particular day that you hope to impress your mother-in-law. "Call it 40Wpc," said Kevin, "but it's not underpowered; it's huge power." There's only one way to find out what that means.

How nice to again make the acquaintance of the folks at Balanced Audio Technology, aka BAT, now owned by Music Direct, and discover their three handsome new preamplifiers. The VK-53SE ($15,000), which replaces the VK-52SE, incorporates the same transformer-coupled output stage as in the flagship REX II preamp, and uses a new amorphous-core output transformer, encapsulated in a Mu Metal case. "There are no caps in the signal path in our preamps," proclaimed Geoff Poor. "The best capacitor is no capacitor." Also new are the VK-33SE preamplifier ($9995), a replacement for the 32SE and a trickle-down beneficiary of the VK-53SE's technology; and the VK-33 preamplifier ($7000), which replaces the VK-32.

Many, many moons ago, in the days when Stereophile was a small digest rather than a full-sized magazine and lively website, I owned an Aragon 4004 dual-monoblock amplifier. Oh how I wish I had never sold my 4004, with circuitry designed by Dan d'Agostino, and instead mated it with a front end, speakers, and cabling that could have revealed all that it had to offer.

You, thankfully, have an opportunity to find out just how good the circuitry is. The just-introduced Aragon 8008, a software-upgradable, 200Wpc dual monoblock amplifier ($4999) with dual, symmetrical power supply and ethernet-based control and status monitoring, is now produced by Indy Audio Labs, who bought the brand from Klipsch in 2009.

On January 10, the third day of CES, Michael Lavorgna, Jon Iverson, Stephen Mejias and I flocked to the Flamingo, home of the T.H.E. Show. There I made a first acquaintance with Coda Technologies, a company based 90 or so minutes from me in Sacramento, California. All Coda products are designed, manufactured, and assembled in the good ole USA, and come with a 10 year warranty, transferrable for 5 years.

Opening the top of Ayre's new AX-5 integrated amplifier ($9950) revealed an impressive layout, with transformers so big that they extend down through the bottom of the chassis. Rated at 125Wpc into 8 ohms, or 250 into 4, the AX-5 uses the same volume control as in the KX-R, and a diamond buffer circuit in the output stage. The amp, driving TAD CR-1 stand-mounted monitors, sounded eminently smooth on a track by Ella Fitzgerald, and did a fine job communicating the smile in her voice.

I ran into Dan D'Agostino, in the hallway of the Venetian. He was hurrying off to a meeting, but had a moment to mention that his amplifiers were being used in live exhibits in several rooms, including YG and Light Harmonic DaVinci, among others. I asked if there was anything new at the show, and he smiled and mentioned the new Momentum preamplifier. I found the D'Agostino room and his partner Petra, showed me the preamplifier, which was on passive display.

Perfect8 Techologies' exhibit suite at the Venetian proved to be one of the most crowded I entered. Perfect's CEO, Jonas Rantila, was introducing his new floorstanding speaker, the Point Mark II Evolution ($115,000/pair). This three-way, speaker features an Air-Motion Transformer tweeter and two midrange drivers mounted on a glass baffle (there's no enclosure for the tweeter or midrange drivers), sitting on a single glass-enclosure housing a pair of 10" subwoofers powered by a 400W, DSP-controlled amplifier hidden within the enclosure. Power for the midrange and tweeter was supplied by a 165 lb, 500Wpc, solid-state Bridge Audio Laboratory (BAlabo) BP-1 Mk.II stereo power amplifier ($88,500). The BP-1's importer, Fred Nadel, told me that the amplifier's output stage runs in class-A for the first 40 watts.
