SSI 2010

Introduced at January’s CES, Sennheiser’s RS 180 wireless headphones ($500) are so light and comfortable, you hardly know you’re wearing them. Rechargeable batteries are concealed within the right earcap, which also holds controls for volume and balance. The ‘phones have a range of 100m, and offered a full, round sound with impressive imaging.

"Oh ho they're playing my song
Oh yeah they're playing my song
And when they're playing my song
Everybody's got to
Sh Sh Sh"

Barrie, Ontario, about an hour's drive from Toronto, with a population of about 130, 000, is not a city that I associate with the design and manufacture of high performance audio equipment. It doesn't have even a single "real" audio store, just Best Buy, etc. But, as I found out at SSI 2010, Barrie is the home of McAlister Audio, maker of the OTL-195 monoblock amplifier and a prototype preamp. The designer is Peter McAlister, who produced his first prototype output-transformerless power amp ten years ago. The OTL-195 puts out 150W, and appears to be a very sophisticated design: fully balanced, able to drive 4 ohm loads, a circuit that tracks the signal level in the driver stage and modulates the control grids of output tubes, and various other circuit refinements. The OTL-195 is hand-built by Peter McAlister himself, and utilizes high-quality parts. The price is $8500/pair. As I mentioned in the blog posting below, the King Sound Prince IIs sounded great driven the McAlister OTL-195s.

I was immensely impressed by the dCS Puccini SACD player and U-Clock when I reviewed the British combination last December. But as the physical discs becomes a legacy source of music, there was obviously a need for a related D/A product. SSI saw the public debut of the dCS Debussy ($10,999 with remote), shown off here by Tempo Marketing's John Quick. The Debussy basically combines the D/A, DSP, and analog board from the Puccini with the true asynchronous USB input topology from the U-Clock in a slim, attractive package. There are two AES/EBU and two S/PDIF inputs, as well as USB, and there is also a word-clock input to allow the Debussy to be controlled by an external master clock unit. Two digital filters are included, one a conventional symmetrical type, the other a variant of the increasingly popular minimum-phase "apodizing" type.

As Art mentioned, Totem always does an outstanding job of transforming a simple room into an environment, and at SSI 2010, they surpassed all of their previous efforts. Here’s a look at a row of Totem Tribe on-walls, dressed in new skins. As loudspeakers are often viewed as the most personal component of any system, it makes fine sense to offer the option of truly personalizing them with art. I can imagine buyers selecting fabrics that match their furnishings, or using their favorite artwork, or even creating their own designs.

The arrangement of Totem's new Tribe 5 wall-mounted speaker in on of their rooms at SSI raised my eyebrows. I asked Totem's main man Vince Bruzzese what gives? "We must reach out to non-audiophiles!" he said, adding that this was one of the impetuses behind the launch of the "skins" that Art Dudley wrote about above. "By arranging these speakers in an unconventional manner but showing that they can still play music, we reduce the fear non-audiophiles have." (My apologies if my paraphrase didn't capture the passion with which Vince spoke.) But the Trentemoller track I listened to, played on Chord CD transport, DAC, and amplifier, didn't sound any the worse for the unusual speaker setup.

Here we see John Atkinson caressing the relatively compact Vivid B1 loudspeaker ($15,000/pair). With the help of a second rear-mounted mid-woofer, the B1 produces a sound far larger than its modest proportions. On A Higher Note’s Philip O’Hanlon tells us that women, in particular, have been fond of this speaker.
