The official closing time of HE 2007 was 5pm on Sunday. I was surprised to see, then, that there were some people registering even as late as three o'clock Sunday afternoon. Now, <I>that's</I> real devotion to the hobby!

Performing music in a group is all about collaboration and communication. Look closely at this picture of the John Atkinson Trio, in performance on the last day of HE2007. JA is playing a solo, and both pianist Bob Reina and drummer Allen Perkins are listening and watching intently. In his comments after the number, Bob said that they had some differences of opinion about how to end the number, and resolving these differences required some give-and-take in the actual playing. Now that's jazz!

...and 3.6kW into 2 ohms! All in a day's work for Krell's $40,000/pair, Krell Evolution 900 monoblock amplifier. On passive display with its top off, you can see that the amplifier has three output modules, each containing a pair of driver stages, 28 bipolar output devices, and a massive heatsink that vents heat in chimney fashion through vents in the top and bottom of the chassis. The power supply features two 3kVA toroidal transformers, 52 electrolytic capacitors, each rated at 1800&#181;F, 900watt, and 105&#176;F. Weight? Again I didn't want to know, but was told it was a mere 175 lbs!

Patrick Chu, creator and designer of the $80,000/pair, two-way, Mandarin Supreme loudspeaker, explained that the products’ name is a synthesis of two words: Loimin means "delightful understanding" and Chay means "ateliar or studio." The frequencies from 750Hz upwards are handled by a 1" tweeter loaded with a 19" horn comprised of alternating layers of cherry and oak wood. The bass, which is rated down to 22Hz, is handled by 10" and 12" woofers. This composite was by far the least active speaker material I've come across. Rapping it with my knuckles was like tapping on granite. The woofer enclosure was made of concrete with a cloth covering. I didn't ask about the loudspeaker's weight because I <I>didn't</I> want to know. The nominal impedance is 8 ohms, and the voltage sensitive a very high 92dB. Although I didn't audition any familiar reference recordings, the speaker had a dynamic sonic texture with a midrange emphasis.

Balanced Audio Technology's Steve Bednarski is a big guy, but he's not a giant, and BAT's Geoff Poor is not nearly as diminutive as he looks in this picture. It's just a matter of perspective with a wide-angle lens. The rack between Steve and Geoff houses the new top-of-the-line Rex preamp, described by Wes Phillips in <A HREF="http://blog.stereophile.com/he2007/0451407rex/">another posting</A>.
