LATEST ADDITIONS

Sonus Faber co-founder Franco Serblin has started a new, eponymous company and two of his speakers, the floorstanding Ktema ($39,995/pair) and bookshelf Accordo ($12,995/pair) were being demonstrated in one of the Axiss Audio rooms in the Venetian. Amplification was all-Air Tight—ATM-3011 monoblocks, ATC-2 preamplifier, ATE-2 phono preamplifier, ATH-2A transformer—with the source a Transrotor Fat Bob S turntable fitted with an Audiocraft AC-3300 tonearm and an Air Tight PC-1 Supreme cartridge. The laidback sound of Norah Jones matched the superb looks of the speakers and the bass was full and warm—which impressed me the more when I realized I was listening to the stand-mounted Accordos, not the larger Ktemas.

At the 2011 CES, Swedish company Perfect8 concentrated on their Force flagship speaker. For the 2012 Show, they brought their Point Mk.II ($115,000/pair with subwoofer modules), which, like its big sister, uses an enclosure fabricated from glass—or rather, from what Perfect8 calls "Super Silent Glass," joined without solvent-based adhesives. The upper-frequency module is a dipole, allowed to roll off naturally to integrate with the subwoofer module below it, which uses two 10" drive-units mounted on its sides to cancel mechanical reaction forces. The woofer's low-pass filter is set at 86Hz and realized in DSP; the module includes a class-D amplifier housed in the triangular section at the rear. Despite my reservations about glass as an enclosure material, both Diana Krall and Rimsky-Korsakov sounded uncolored and natural.

When I gave my Richard Heyser Memorial Lecture at last October's AES Convention, THX's Laurie Fincham was sitting in the audience. Afterwards, Laurie whetted my appetite for what the company would be presenting at CES: a patented non-switching power amplifier topology that would be as efficient as a class-D amplifier but without the side-effects that afflict such designs, high levels of radiated RF, for example. In the photo, Laurie is pointing to the power supply of the amplifier. DC is fed to two oscillators running at 25kHz, one generating a sinewave, the other a cosinewave, ie 90° out of phase with the sinewave. Each wave feeds a transconductance amplifier in the primary of a small transformer; the output of each secondary is rectified and summed to produce a high DC voltage which is then used to power the amplifier circuit. There are no storage capacitors in the circuit—it looks as if almost all the energy entering the supply is available as the final DC voltage! The new topology was developed by Fincham, Owen Jones (the twin brother of TAD's Andrew Jones) and Andrew Mason.

Constellation brought their new Jetsons inspired Cygnus DAC to CES, shown here in the hands of VP of Engineering Peter Madnick. The DAC contains four 32/192 DACs in a stereo balanced configuration, with separate DACs used for the positive- and negative-going signals of the left and right channels.

Inputs include USB, SPDIF, AES and Toslink and it looks like they've dropped the CD transport that was included in the demo at last year's CES. Price should be around $20k.

UK manufacturer Astin Trew had their new DAC 1 on display. Managing Director Michael Osborn was on hand to answer questions and look for US distribution for his products. The DAC 1 features asynch 24/192 USB as well as FireWire and I2S inputs. It has a 6922 buffered tube output stage for single-ended connections and solid state for balanced output. Price should be around $4,500-$5,000 and would arrive in about 2 months once distribution is set up.

Based on the popular Oppo 93, Primare was displaying their universal player that will retail for $5495. It plays all the typical Oppo disc formats including 3D Blu-ray and has custom audio, video and power supply circuitry. The BD32 is a gorgeous-looking product and the photo does not do it justice.

I'd file this one under DAC/preamp/streamer, with plenty of features and more to be announced. What we know: based on the company's DAC 8, there will be six digital inputs including all the usual suspects as well as wired and wireless networking, vTuner and UPnP. The DAC can upsample to 24/192 and includes a front panel display for control info and selected meta-data via DLNA/UPnP networked devices. Price will be around $15k.
