Aerospace engineer James M. Harrell, Jr. debuted his Jumping Cactus Loudspeakers at RMAF 2007. Only available from jumpingcactusloudspeakers.com, these tri-amped, 120lb loudspeakers are housed in sealed aluminum cabinets that feature a Bubinga wood front panel. The speakers are said to have a high measured sensitivity of 94dB. With a frequency range of 65Hz–20kHz., a subwoofer is recommended. The speakers also come with an active XM44 4-way crossover by Marchand Electronics.

Kara Chaffee has every reason to smile even wider than she's smiling here. Her DeHavilland GM-70 50W SET monoblocks ($11,000/pair) and Ultraverve remote preamp ($2995) were creating one of the most wondrous, air-filled soundstages I have heard. "We aim at the heart of the music," she told me after I had spent a while listening to some of my favorite CDs.

Art loudspeakers, made in Scotland, paired up German-manufactured audio components from AcousticPlan and a line transformer from Japan to make their joint US debut at the 2007 RMAF. In two adjacent rooms, I heard two different Art models. As depicted in the photo with Art's Derek Dunlap, I first auditioned the art Stiletto 6 loudspeaker ($5000/pair), mated with AcousticPlan's Sitar hybrid-design integrated amp ($7500, complete with external power supply), Audio Technic line transformer from Japan (also debuting), and Cary Audio CD player. The Stiletto, a vented two-way made from birch plywood without use of MDF, measures 88.5dB sensitivity and has a fairly linear frequency response that starts at the mid '30s. It features a SEAS 6" coated-paper driver and a 1" soft-dome tweeter equipped with a proprietary horn to create a delightfully open soundstage. I was quite impressed with this system, which produced very warm, rich sounds that belied the speaker's diminutive size.

Sean O'Hagan asks, "where are the heirs to awkward buggers like Robert Wyatt?"

By blimp, of course.

I’ve listened to Herbie Hancock’s new CD, <I>River: The Joni Letters</I> (on Verve), three times now, and it gets better with each spin. This is a Joni Mitchell tribute album, with Hancock on acoustic piano heading a straight-ahead jazz quintet (including Wayne Shorter on soprano sax and Dave Holland on bass), fronted on six of the 10 tracks by various singers.
