LATEST ADDITIONS

I first discovered the Eficion F300 loudspeaker ($14,800/pair) at RMAF 2008, where its full-range sound deeply impressed for the price. Since then, the speaker has undergone numerous refinements. Split into two separate compartments, separated by Stillpoints, this is a 3-way 4-driver vented box with a frequency response of 25Hz–40kHz, 89dB sensitivity, and 8 ohms impedance, with a minimum of 6.4 ohms. The front tweeter is an Air Motion Transformer, its rear-firing super tweeter a Heil ESS aluminum ribbon, and its 7" midrange and 12" woofer both from Aurum Cantus. All this has produced a more controlled and detailed sound. Other refinements are identified on the Eficion website.

At least two people I know came up to me in the hallways of the Marriott to urge me to check out Intuitive Audio's new Gamma Summit speakers ($10,000/pair). As soon as I walked into the room, the fabulous bass on Patricia Barber's rendition of "Keep on Using Me Until You Use Me Up"—I'm guessing at the title—told me why. The system's riveting presentation also featured the kind of musical highlights for days that audiophiles love. Next I heard the same Mahler Symphony 2 recording I've been playing a lot at RMAF 2009. The speakers did an extremely fine job of controlling and highlighting the bass line, and also sounded very vibrant on top. Congratulations to designer Dale Pitcher for a job well done.

<B><I>Stereophile</I>: </B>You are president of Esoteric Audio Research, a British manufacturer of tube amplifiers, and a world-renowned designer of tube equipment and output transformers. I thought we'd begin with a little background. Where were you born? What kind of education did you get to prepare you for a career in audio?

One of the first rooms I visited at RMAF was the one shared by Luxman and Vivid distributor On a A Higher Note and cable manufacturer Synergistic Research. Auditioning the South African Vivid Giya speakers ($58,000/pair) had been a <A HREF="http://blog.stereophile.com/ces2009/vivid_vivids/">highlight of the 2009 CES</A> and I wanted to repeat the experience before the speakers wended their way to Wes Phillips' place for a forthcoming <I>Stereophile</I> review.

I was glad that Darren and Bonnie Censullo's Avatar Acoustics demmed four new products at RMAF, because they created a synergistic match that produced beautiful sound.

Every once in a while, an artist or album will pop out of the background and renew your love of music. Which single album has really stood out for you recently?

Until I encountered the world premiere of the imposing Wharfedale Airedale Neo loudspeaker ($20,000/pair), I hadn't run into speakers from the 70-year old company in many a year. The wait was worth it. This wonderful-sounding speaker, which weighs over 125 lbs and can handle up to 400W power, boasts point-to-point wiring, frequency response of 25Hz&#150;45kHz, and 88dB senstivity.
