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.

Stromtank S-4000 ProPower MK-II XT computer-controlled battery power source

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.

EMM Labs DA2i D/A processor

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.

Recording of March 2025: Alec Frank-Gemmill: Mozart Horn Concertos

Mozart: Horn Concertos
Alec Frank-Gemmill, B-flat horn; Swedish Chamber Orchestra, Nicholas McGegan, cond.
BIS-2635 (reviewed in native 24/96). 2024. Thore Brinkmann, prod.; Brinkmann, Håkan Ekman, engs.
Performance *****
Sonics ****½

When I recollect the soundtrack to my acid-tinged summer of 1967, several LPs stand out: The Beatles' Sgt. Pepper's you-know-what, The Rolling Stones' Their Satanic Majesties, Richie Havens's Mixed Bag, and Dennis Brain's equally famed recording of the Mozart Horn Concertos, with the Philharmonia Orchestra conducted by Herbert von Karajan. Though all of them sounded potent and execrable, in equal parts, through our starving–ex-student record players, neither the Mozart's monophonic provenance nor the too-distant sound of Brain's horn could diminish the joy it brought me...

How wonderful it is to revisit these tuneful, often jolly concertos played by a superb horn virtuoso, Alec Frank-Gemill, backed by the Swedish Chamber Orchestra conducted by one of the world's most distinguished period-practice authorities, Nicholas McGegan.
