LATEST ADDITIONS

As I think I wrote somewhere, it's one thing to hear equipment at a show, another thing to hear it at home. I meant to imply that, of course, at home is the only way to truly hear a piece, in your reference system.

But at AXPONA, where George Counnas (center) and Carolyn Counnas (right) debuted their new Zesto Audio Eros 500 Select KT-150 equipped, class-A monoblocks, with Zesto Audio's Leto Ultra II preamp, which I reviewed in January 2021, I was flummoxed at the beauty of sound, extravagance of liquidity and detail, and nearly spiritual physicality the system endowed to a variety of music.

Two months ago, at the audio expo in Tampa, I stumbled upon a pair of most intriguing French speakers. The $8000/pair Diptyque 107 is a medium-sized planar magnetic whose designers, Gilles Douziech and Eric Poix, make no secret of their love for Magnepan. All the same, the duo has sought to improve on that company's famed panel technology, mostly by addressing a perennial shortcoming of such dipoles: their lack of deep bass.

I wasn't necessarily expecting to find Alon Wolf (right) striking dangling bars of aluminum with a small mallet. Had Magico's celebrated designer embarked on a second career as a percussionist? Nah. He was demonstrating to Stereophile Editor Jim Austin (left) and myself that aluminum, which Magico has long used as the ideal material for its enclosures, rings, but can also be very effectively dampened by sandwiching a proprietary elastomer between two layers of it. The first (untreated) bar rang like a bell. The second one had a padded adhesive backing that took away about 80% of the effect. The last bar was the aforementioned sandwich, and yup: dead. No ringing.

Washington DC area distributor Notable Audio showcased products from Joseph Audio, Doshi Audio, J Sikora, Berkeley Audio Design, and Cardas Audio at AXPONA. Notable's Jeff Fox had put together an impressive system, with a mix of brands we have seen used together at many prior shows to great effect, only this time he used the best of everything to create a system that really sung.
