CES 2010

Also showing in the Ayre room were their MX-R monoblocks ($9250 each) and also a Stereophile “Product of the Year” in 2007), connected to the actual samples of Vandersteen Model Seven speakers that Michael Fremer will be reviewing for Stereophile in March. The MX-R, like its KX-R brother, is carved out of a single block of aluminum and puts out 300W into 8 ohms and 600W into 4 ohms. The amps were fed by Ayre’s CX-7eMP CD player and KX-R preamplifier and the sound of the MX-R amps driving the Vandersteen Sevens was detailed and— pun fully intended— airy.

Here's Ayre's Steve Silberman holding the new DX-5 universal player that can handle not only SACD, CD and DVD-Audio, but also DVD and Blu-ray discs. Think of it as an Oppo BDP-83 on super steroids. In fact the company starts with an Oppo drive and MPEG processor and throws everything else out, adding in a new power supply and all the important digital bits. Wrapped up in a beautifully machined package and retailing somewhere around $10,000, pre-orders begin next week, and deliveries should happen sometime in the first half of February.

B&W's openng day press conference at the LVCC revealed an entirely new line of Diamond Series loudspeakers in a new piano-black finish. This new vintage comes from the line of monitors that included the Diamond Silver Signature ,an $18,000/pair high-end two-way that had been produced in a limited run of 1000 pairs. The smallest member of this speaker line is a two-way, stand-mounted monitor called the B&W 805 Series Diamond, a strong value at $5000/pair. The stands are extra, but are now available in black.

The Rockport Alya's 1.25"-thick front baffle is cast from aluminum, then machined to accommodate the drive-units. The tweeter's usual front-plate is discarded and replaced by the baffle, which has the necessary opening and locating pins. This gives a very clean acoustic environment for the dome. Andy Payor's hand is shown here locking the tweeter into place with a ring that screws into a thread tapped into the rear of the baffle.

Siltech's Edwin van der Kley handed me his new preamp. There were no wires attached, but the four tubes were glowing. "It's battery-powered, and I could use a low 25V voltage rail for the tubes because they are ECC86 dual-triodes, which were developed for car-audio and microphone use." Edwin went to explain that as this tube uses a 6.3V heater, he could run the heaters of the four tubes in series from the same 25V supply. It also offers very low 1/f noise for a small-signal tube, he told me. Siltech has a plentiful supply of the tubes and the preamp wil sell for $28,000.

Minneapolis-based Bel Canto Design (props to my homies) brought a new amplifier to CES this year. The e.One REF150s ($1495, shown on the lower rack) is a fully balanced dual-mono amplifier that will put out 150Wpc into 8 ohms This may be a wee-sized amplifier, but it sounded huge strapped to a pair of new Joseph Audio bookshelf speakers.

For those of you who lust after a Benchmark DAC but wish it had remote control, rejoice. And in typical pro-audio fashion, they didn't add just any remote, but a motorized Alps pot that turns the front panel knob. The company claims that digital volume controls can reduce dynamic range and analog IC type controls add distortion and noise, hence their custom motorized design.
