"That's a familiar sight—and a familiar sound." When I walked into On A Higher Note's large room on the Denver Tech Center Marriott's mezzanine floor, the speakers being demmed were the Vivid B1s that I review in the October issue. I loved the sound of the $14,990/pair B1s in my room and they were doing equally sterling duty at RMAF, driven by a Luxman M600A amplifier ($8500) and a modified Revox open-reel recorder. A 15ips tape of a cello, piano, and double bass playing what sounded like a tango by Astor Piazolla, recorded in LA's Disney Hall by Yarlung Records, had an ease to its sound that allowed the music to flow. The room had a touch too much bloom in the upper bass—perhaps the Synergistic "magic bowl" you can see on the post on the wall behind the speakers was fatigued after a long day adjusting the room acoustics.

“In nature, sound has three elements,” explained BSG Technologies’ Larry Kay: “Amplitude, frequency, and phase.”

At a hi-fi show, there are many different types of demos. In some, there is music played casually, seemingly without much thought, selected either by the host or by an attendee; in others, music is carefully selected and introduced by your host, each track used to display certain characteristics of the system at hand; in others still, music is certainly played, but only after attendees are offered a detailed explanation of the gear in the room&#151we learn about the technologies employed and the work that went into creating the product&#151and we might even learn something about the art and science of listening. These last rooms are like demo-lectures, and they’re my favorite rooms. I feel like I’m in a classroom again, with one of my favorite professors.

Similar to the system we enjoyed at the California Audio Show, here we heard the beautiful Sony SS-AR1 loudspeakers ($27,000/pair) with Pass Labs X600.5 power amplifiers and XP-20 preamplifier, Parasound Halo JC3 phono preamp, Clearaudio Concept turntable, and an EMM Labs XDS1 SACD player. Speaker cables were Kimber Kable's KS-3033, interconnects were Kimber's KS-1111, and AC cables were Kimber's PK-10 Gold.

The system sounded rhythmically nimble and certain with big, fleshy images, a rich midrange, and warm, full bass. Easy to listen to and easy to enjoy.

Something strange and awesome was going on in the Zu Audio room. The lights were low, an evil but alluring sound was filling the room, and the company’s Sean Casey was crouched down in a corner, surrounded by vinyl.

Here we see AudioStream’s Michael Lavorgna in serious listening mode. (We can’t seem to keep him away from vinyl.) The album is Edward Ka-Spel’s O Darkness! O Darkness!

1. This show is massive. I think John Atkinson and I are feeling a bit overwhelmed by the number of exhibitors. I’m not sure that we’ll be able to see and hear everything that is on display. A strategy: John will start in the Tower and I will start in the Atrium, and tomorrow, we’ll compare notes and examine what we have and have not achieved. Meanwhile, Michael Lavorgna will cover computer audio for AudioStream, and Tyll Hertsens will cover headphone gear for InnerFidelity.

In 2010, sales of motorcycles equipped with sidecars accounted for only 4% of total motorcycle sales in the US. But that was a significant increase over 2009, which was itself an increase over 2008. While numbers remain low overall, sales of sidecar motorcycles are going up at a decent rate, while sales of most other motorcycles are in the toilet.
