AXPONA 2013

Playback of DSD files from a computer via USB is a hot topic right now, but at AXPONA Mytek upped the ante by playing 5.1 multichannel DSD files, using three of the preamp version of their Stereo192 DSD-DACs ($1595 each)linked together, with the files played with J River Media Center. The system included five of the Sony SS-AR2 speakers that I had liked so much in my review last September, driven by Pass Labs amplifiers, with Sony's new SA-NA9ES subwoofer fleshing out the bottom octaves. Not that the system needed a subwoofer—with multichannel playback, the low-frequency "room gain" is greater than it is with two-channel.

I loved the TAD Compact Reference CR1 speakers when I reviewed them in January 2012. And I am also a fan of the Parasound Halo JC1 monoblock amplifier. But when I walked into the Blue Smoke room at AXPONA and saw the latter driving the former, I was a little taken aback as this is not a combination I would have thought worked well together, both speakers and amplifiers tending toward the lean and clean side of things. But only a fool would allow his expectations to affect what he heard and the sound in the room was superb: clean, yes, but not lean; a rich, extended low end but without bass boom; and a wealth of detail with the feeling of anything being spotlit. The MSB Diamond DAC 4 with Femto Clock, the Argento cables, and the Bag End Electronic Bass Traps must have had something to do with the great sound, of course, but the source, Blue Smoke's new Black Box II (to be priced around $8000 when available) must have been the key.

Together with Chicago retailer Holm Audio, Nordost was conducting one of its ever-popular cable and support demos. Taking over where the now retired Lars Christensen left off, Nordost Eastern Regional Sales Jefe Steve Greene let folks hear differences between Blue Heaven, Red Dawn LS, Heimdall 2, and Frey 2 interconnects, speaker cables and power cords by calling into play a Hegel H300 250Wpc integrated amp with built-in DAC ($5500), Hegel CDP4A CD player ($4000), Sony's new SS-NA2ES loudspeakers ($10,000/pair), and, from Nordost, a QB8 distribution bar ($1399.99), two QV2 AC Line Harmonizers ($350 each), and a QX4 Electro-Magnetic Field Stabilizer ($2699.99). Nordost's three levels of equipment support Sort Kones were also compared.

Ever since encountering the wonderful sound of Nightingale electronics, manufactured by Simetel of Rome (as in Italy), at the first AXPONA show in Jacksonville, I've looked forward to another visit with their Lancaster, PA-based USA representative, Valentina Ross. Her set-up of Nightingale Concentus open-baffle CTR-02 loudspeakers ($9750/pair), Onda 90 monoblock amplifiers ($12,450/pair), PTS-03 preamplifier ($9750), CR-1600 line conditioner ($3960), and unnamed source and cabling—her assistants, who handed me literature, spoke little English—was one of the most attractive at the show, and the sound remarkably open and spacious.

That is not a feeble attempt at a joke; it really is how Mr. Freud forced this Contributing Editor to slip on the word “editors.” Perhaps I was thinking of The Absolute Sound Executive Editor Jonathan Valin, who not only pulled a no-show for the Friday and Saturday afternoon 90-minute Editors panels—pre-show promotion and the show guide had advertised his participation, with Robert Harley—but also attempted to erase from history, in his online AXPONA report, the rather significant fact that the last major audio show in Chicago was not the 1994 Consumer Electronics Show, as he claims, but rather in 1999, when the Stereophile show came to the Windy City. Is such competitiveness really necessary, given how different the two magazines are?

The moderator for both panels was the extremely articulate and informed Bes Nievera of Music Direct and also a host on Chicago area public radio station WDCB, who just happens to be a long-time audiophile. Panelists included (left–right), from TAS, Editor-in-Chief Robert Harley; from DaGoGo.com, Senior Editor Ed Momkus; from Stereophile and an embarrassingly long list of other publications, Contributing Ediot Jason Victor Serinus, and Stereophile’s Editor-in-Chief John Atkinson.

The mighty Focal Grand Utopia EM loudspeakers ($190,000/pair), which use field-coil energized woofers, took pride of place in one of the two big rooms on the Doubletree's ground floor sponsored by Chicagoland dealer Quintessence. Driven by two-chassis Pass Labs Xs300 monoblocks with Kubala-Sosna cabling throughout the system, both the 1950s Duke Ellington and Johnny Hodges collaboration "Back to Back" and the Reference Recordings Rutter Requiem were reproduced with a stunning combination of vocal purity and instrumental majesty. Source was a file fed by USB to a Playback Designs player/DAC.

Chicagoland dealer Quintessence devoted a large ground-floor room to the Fine Sounds groups of companies—Sonus Faber, Audio Research, Wadia, and Sumko/REL—along with the superb racks from Harmonic Resolution Systems and a Clearaudio/Benz Micro LP player. A pair of the Sonus Faber Amati Futura speakers that I reviewed in May 2012 ($36,000/pair) was being vertically bi-amped with two tubed Audio Research Ref250 monoblocks driving the midrange/tweeter sections and two solid-state Audio Research DS450M monoblocks for the woofers. No fewer than four REL powered subwoofers were handling the low bass. Preamp was the Audio Research Ref5 SE that Brian Damkroger and Bob Reina raved about in Stereophile.
