Before I heard the new Soulution 717 monoblocks ($109,975 each), I spoke with Cyrill Hammer, Soulution’s CEO and Chief Designer, and Cliff Duffey, President of AXISS Audio. The conversation was illuminating. The listening? Something else entirely.

Watch our exclusive video interview with Cyrill Hammer and Cliff Duffey.

At an early-morning breakfast, Michael Børresen, co-founder and chief designer of Audio Group Denmark, unveiled the Børresen M2 loudspeakers ($190,000/pair) and their companion Bass Modules (price to be announced). Also shown for the first time in North America was the Aavik R-880 phono preamplifier ($70,000), designed to work with DS Audio optical cartridges. The R-880 enables users to adjust high cut, low cut, and absolute phase on the fly.

Arturo Manzano, long a fan of Koetsu phono cartridges, has reassembled Koetsu’s original team of artisans to return the legendary brand to the international market.

The largest and most important audio show in the United States, AXPONA, is poised to open in the greater Chicago area’s sprawling Schaumburg Renaissance Hotel & Convention Center. Well before the three-day show opens on Friday, April 11 at 10am, you can expect scores of eager attendees lining up at the long registration desk in the Convention Center lobby.

In my enthusiastic 2022 review of the Stromtank S-1000 ($16,900), I described the Stromtank as a computer-controlled lithium iron phosphate (LiFePO₄) battery array that, coupled with its AC inverters and all the trimmings, supplies clean, constant, stable off-grid AC power to hi-fi components. By softly depressing a single button on the front panel, Stromtank owners can easily switch from wall-connected mode (when the Stromtank's dimmable front-panel meter is blue) to a disconnected, battery-only state (when the meter is green). At the end of a listening session, users can return to blue mode to recharge the battery array.

More than five years have passed since I evaluated the original, Canada-made DV2 D/A converter ($30,000 in 2019) from EMM Labs. Since then, I've heard it and other top DACs—many of them at audio shows; some in my reference system—and my appreciation for what the original DV2 could deliver has only increased.

Now arrive two new components, the DV2's twin successors: the DV2i, an "integrated" stereo D/A converter with a software-driven, high-resolution digital volume control, and the subject of this review, the DA2i, a straight D/A with no volume control. Both cost $35,000.
