There are always chance encounters at an audio show, and when I went to meet AVTech America's general manager Keith Pray (left) and Hi-Fi News editor Paul Miller (right) to discuss, among other things, November's Hi-Fi News Show in Windsor, England, Audeze CEO Sankar Thiagasamudram was with them holding a sample of the California company's new Mobius head-tracking headphone ($399). The Mobius uses planar-magnetic diaphragms like the upmarket Audeze cans, but once zero'd in the forward direction, will keep the soundstage aimed at that direction when the user moves his head. In this the Mobius is similar to the Smyth Realiser, but is both considerably more affordable and doesn't need an external control unit. This headphone is not aimed at the high-end audio market but is ideal for gamers, who need the stereo soundstage to remain aligned with the image on the screen.

Although most rooms I visited at the end of RMAF 2018 offered fine sound, I single out the new Dragonfire Acoustics Mini Dragon self-powered desktop system ($10,000 total) for two reasons: a) its designer, Dragoslav Colich (aka Dr. C), who continues to design every Audeze headphone, calls these first desktop planar speakers from his new company his "life achievement…the finest transducer I have built," and, b) they sound fantastic.

In the Musical Surroundings room I discovered a once-in-a-lifetime coincidence: a system that contained four products that were reviewed or used in reviews in the October 2018 Stereophile, plus a somewhat more expensive sister of one of the two products that appeared on the cover: Audio Research Ref 160M mono amplifiers ($30,000/pair) and Reference 6 line stage ($14,000), Sonus Faber Aida loudspeakers ($130,000/pair), DS Audio Master1 optical phono cartridge and EQ ($22,500), and Hana ML MC cartridge ($1200).

That title will surely get a rise out of some folks!

Be that as it may, the aforementioned company ran two MQA Live events at RMAF, during which high-resolution (24/192) MQA streams of live jazz ensembles were streamed in real time to various rooms at the show. MQA claims that the streams were essentially analog to analog, right off the desk.
