I've been listening to a lot of mid-priced, sealed headphones lately, and these just keep jumping out at me. They say DJ on the side and have a mono switch, but I'm not buying it ... these are just plain good headphones.

Pioneer, eh? Who'da thunk it.

Best sound apart from violinist Arturo Delmoni, that is. I am reviewing TAD's Compact Reference CR-1 three-way stand-mounts ($37,500/pair plus $1800/pair for stands) for a Fall issue of the magazine so I was interested in seeing what kind of sound TAD's chief engineer Andrew Jones was getting from the CR-1s in the room TAD was sharing with its New York dealer, Triode Picture+Sound. Though there were a pair of Atma-Sphere tube monoblocks in the room, the speakers were being driven by TAD's solid-state amplifier with the source Andrew's MacBook Air running Decibel and feeding data to a TAD DAC via USB. I listened to several hi-rez recordings at 176.4kHz and 192kHz from Chesky and ex-Sheffield Labs engineer Bill Schnee, whose recording for Bravura Records of a band led by drummer Simon Phillips had one of the best recorded drum sounds I have heard. Even in the cramped and crowded hotel room, it was obvious that these speakers, with their coaxial, beryllium-diaphragm midrange/tweeter and reflex-loaded 8" woofer with a 4" voice-coil, were doing something out of the ordinary with respect to freedom from compression.

It was déjà vu all over again when I went into the MBL room at Axpona (after a wait in the corridor outside, this room being packed throughout the Show). The system was the same used at SSI in Montreal and Axpona in Atlanta last April—101E Mk.2 omnidirectional speakers driven by gigantic 9011 monoblock amplifiers, a 6010D preamp, a 1621A CD transport, and a 1611F D/A converter—but this time with everything finished in a superb gloss white. I listened to "Fit Song" from Cornelius's Sensuous CD, "The Boy in the Bubble" from Peter Gabriel's Scratch My Back CD, and the hi-rez solo piano recording made by MBL's long-time chief engineer Jürgen Reis, "Walchensee, Mondnacht," performed by Martin Vatter, from the album Klangbilder. All the music was being played from a Linux music server put together by MBL's Jeremy Bryan and fed via an asynchronous USB link to the MBL DAC.

The room was a little on the small side for the speakers, with their extended LF response and omnidirectional highs, but that aside, the sound rocked, with an enormous and well-defined soundstage drawing me into the music.

The line outside the AIX room at Axpona, like the line outside the MBL room, was evidence that something special was happening inside. Mark Waldrep of AIX Records prefaced his AV demonstration with an interesting—and amusing—discussion of how difficult and expensive it can be to film in 3-D. There followed one of the most convincing performance clips I've yet to see: fingerstylist Laurence Juber playing a number called "White Pass Trail" on his signature Martin guitar. During the second part of this instrumental, Juber switched from mere picking to actually slapping the strings over the guitar's fingerboard extension (slapping the body, too, for percussion), and the five Thiel SCS4T loudspeakers ($3690/pair) captured perfectly the speed and impact, along with the color and texture, of those sounds. By this time of the show my wife had joined my daughter and I, and she shared my surprise at how the 3-D effect enhanced, rather than tarted-up, the performance. An impressive recreation of superb music.

May Audio Marketing's Nabil Akhrass (seated) was even busier than usual at this show, given the absence of his sister, Julia: She recently gave birth to her and her husband's first child (congratulations!), and decided to sit this one out. When I visited the May Audio exhibit on Saturday morning, they were already enjoying brisk sales of CDs and vinyl.

John Marks brought violinist Arturo Delmoni to Axpona New York, who in turn brought his 18th-century Guadagnini—and his virtually unique mastery of the Romantic approach to solo violin. His Friday afternoon performance of the Ciaconna from Bach’s D-minor Partita held the audience spellbound, with extraordinary intonation, oceans of tone, and a passionate, emotional one-ness with Bach’s music that prompted JA to comment, appropriately: “The man was on fire.”

JA was sitting at the back of the ballroom and was surprised by how loud the sound of the solo violin was. Whipping out his iPhone with the Studio Six Digital SPL Meter app, he measured the typical sound pressure level at 72dB(C).

Speaking of the devil: Here's JM himself (right), posing with Arkiv Music's Robert Garcia, who is also associated with that company's classical music quarterly Listen.

John Marks also arranged, courtesy of Audio Power Laboratories and Wharfedale, to present Arturo Delmoni performing the slow movement from Karl Goldmark’s Concerto for Violin in their room. Arturo played live, but Steve Martorella playing his transcription for pipe organ of the orchestral part was recorded by John Marks in the First Baptist Church in America and played back from CD over the Wharfedale Neo Airedale speakers. The result was impressive, both on the grounds of the system’s sound quality, with extended low frequencies demanded by the organ, but also for Dr. Delmoni’s lyrical virtuosity. This wasn't so much Live vs Recorded and Live with Recorded.

We all owe John Marks a big "thank you" for bringing live music to Axpona New York.

A challenge for the journalist who can’t read his own notes (that would be me): The need for information regarding the Mark Neumann loudspeaker shown above led me to the world-wide web, but a Google search on the words Mark Neumann returned mostly hits that had nothing to do with audio and everything to do with politics. (It was a little like reading one of my old columns. But just a little.) I returned to my senses and visited the website of Miami’s High End Palace, the Axpona exhibitor that brought the mighty Coliseum XLS loudspeaker (approximately $40,000/pair) to New York, and learned that this open-baffle speaker’s design was inspired by a concert grand piano—and that only 12 are made each year. Fed by a Stahl-Tek CD player and driven by Tact and BAT electronics, the Coliseum XLS sounded impressive in a number of ways, although its considerable bass response tended to overwhelm the smallish room.

The sign on the door said JIB Germany, leading me to expect…well, something very different from what I found. (As the late Vivian Stanshall declared in a Bonzo Dog Band number titled “Shirt”: ‘24-Hour Cleaners’? That’s just the name of the shop, dearie!) That said, the exhibitors in this room demonstrated a pleasant-sounding mini-system, comprised of a Napa Acoustics NA-208A hybrid tube integrated amplifier ($399) and NA-208S two-way loudspeakers ($199/pair), fed by a first-generation iPod playing Abba songs.
