"Why is there a box of parts next to each of the Evolution loudspeakers?" I jokingly asked Blue Light Audio's Jonathan Tinn. He explained that those were the external crossovers for the three-way Maestoso loudspeakers ($18,900/pair) with their lids off. The speakers were being driven by the darTZeel NHB-108 Model Two power amplifier ($44,000), which was making its North American debut at AXPONA, and preamp was that Mikey Fremer favorite, the darTZeel NHB-18NS Mk.II ($44,000 with phono stage).

"Good grief! They are using Quads!" I used to use Quad ESL-57s in the mid 1980s before I moved to the US and in some ways, no other speaker has come close to the sonic transparency offered by these idiosyncratic-looking electrostatic speakers. But to see and hear an original pair dating from 1958 in the room shared by Michigan dealer/manufacturer Nokturne Audio and Lejonklou HiFi from Sweden was a highlight of the 2019 AXPONA.

Manley Labs' firebrand CEO EveAnna Manley always seems to enjoy audio shows and AXPONA was no exception, where she was showing off the Absolute Tube headphone amplifier ($4500) in the Ear Gear Expo.

I was impressed by the new Monitor Audio Gold 300 speakers when I auditioned them at the recent Montreal Audio fest. At AXPONA, Chicago retailer Saturday Audio Exchange was showing off the smaller Gold 200 tower ($5000/pair) and Gold 100 bookshelf ($2100/pair) driven by a Roksan Blak integrated amplifier ($4499) and Black CD player ($3999) and hooked up with AudioQuest cables. Like the 300, the smaller speakers feature midrange units and woofers that use Monitor Audio's RDT II (Rigid Diaphragm Technology) sandwich diaphragms, with a "Micro Pleated Diaphragm" tweeter.

Jolida Audio began life a fabricator of vacuum tubes. But since the early 1990s, it has been known for its musical-sounding, modestly priced tube amplification. Jolida was also famous for its association with Jim Fosgate, famous for his Dolby Pro Logic inventions and, more important (to me at least), his battery-powered cartridge-azimuth alignment tool, the Fozgometer. Which I use all the time.

My personal selection for Stereophile's 2018 Product of the Year was the super-resolving, highly-involving TAD Micro Evolution One loudspeaker ($12,495/pair). I heard it first at a MoFi demonstration at an audio show. Wherein I repeated the words "wow" and "my god" over and over. Think goosebumps and awe. But I never thought, or imagined, how much more fleshed out and expansive the ME1s could sound with another octave of energy at the bottom. This year, in the second Tenacious Audio room, the $27,995/pair TAD Evolution E1TX-K loudspeakers produced a much larger and more forceful energy field—with an enhanced octave to octave tonal balance. The E1TX-K's dual 7" woofers and CST coaxial mid-tweeter array delivered an extremely beguiling transparency.

The impressive-sounding room from dealer Audio Video Interiors featured the Anthem STR integrated amplifier ($4499) that Tom Norton reviewed for Stereophile in July 2018. Speakers were the Paradigm Persona 3Fs ($10,000/pair), a smaller sibling to the similar-looking Persona 5F ($17,000/pair) that Kal Rubinson reviewed in October 2018.

The final MoFi Distribution room I visited at the show featured the version of the classic BBC LS3/5A minimonitor made by Falcon Acoustics that I reported on in our report from the 2018 RMAF. This is said to be the only version currently manufactured that is truly identical to the original and was very favorably reviewed by Herb Reichert in October 2017.

Ken Micallef was impressed by this British company's CDA2 Mk.2 CD player/DAC ($4249) when he reviewed it in the January issue, and ATC were using it as the souce in their room at AXPONA. But pride of place went to their SCM50 tower speakers ($22,000/pair, far right in my photo) and the similar-looking SCM50SE powered towers ($60,000/pair, near right).

Look at that photo and notice the elegant wood grille on the Gershman Acoustics Grande Avant Garde loudspeaker ($13,000/pair). How good does that speaker look in person? I put a high value on imaging and what an orchestra looks like between the speakers. Therefore, I prefer speakers with grilles: Exposed drivers distract me from the sound and the illusion . . .
