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.

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.
