Reviewers' Choice This could be the easiest review I’ve ever written. Or the hardest. This here speaker in my room right now, the DALI Epikore 9, is so closely related to the Epikore 11, which I reviewed back in March 2024, that it’s essentially the same speaker with two fewer woofers.

When was the last time a reviewer trotted out the dollars-per-pound trope? I haven’t used it for at least a decade. I’ve reviewed a lot of large speakers over the last two years—big, room-dominating, expensive, luxurious, endgame speakers. The Estelon XB Mk II. The DALI Epikore 11. The YG Acoustics Peaks Ascent. Most recently, the Bowers & Wilkins 801 D4 Signature.

Reviewers' Choice For more than 25 years, the AVID Acutus has been regarded as one of the world’s finest turntables. A brainchild of Conrad Mas, who heads AVID HiFi to this day, the fundamental design of the Acutus has remained largely unchanged since its introduction in 1999: a heavy subchassis and 10kg platter hung from three sprung suspension turrets held in position by elastomeric bands and driven by an AC motor via twin rubber belts. Of course, the Acutus line of turntables and associated power supplies have undergone many refinements over the years.

Reviewers' Choice Close your eyes and picture a chair. This image in your mind is the ideal of a chair, of how a chair should look. The Platonic conception of a chair. That chair may not exist in the real world, but it’s what you think a chair should look like.

Reviewers' Choice Origins

The vinyl era dates back to 1948, when Columbia Records issued the very first 33rpm LP, a recording of Felix Mendelssohn’s Violin Concerto in E Minor, with soloist Nathan Milstein and the New York Philharmonic Orchestra under Bruno Walter. But it wasn’t until the mid-1960s that the challenge of keeping records clean was seriously addressed. That happened when Percy Wilson, then technical editor of the UK classical-music magazine Gramophone, wrote a series of papers on the subject for the Audio Engineering Society.

Reviewers' Choice At Munich’s High End 2024, I spent an inordinate amount of time browsing the European Audio Team display. Their booth was encircled with turntables and tube electronics, two 20th-century technologies with which I’ve had a long-standing love affair. My relationship with EAT goes back eight years, to 2016, when I reviewed the company’s C-Major turntable. I got a real charge out of that ’table, out of its combination of visual low-slung elegance and excellent sound quality.

Reviewers' Choice The term “integrated product” can mean many things in the audio industry. In browsing through the North Collection of components on Simaudio’s website, you will find several integrated products differentiated by number-based identifiers, each positioned opposite its functional counterpart. The 641 integrated amplifier ($11,000, all prices in USD) and matching 681 streaming DAC ($12,000) are the most wallet-friendly products in the North Collection. The 700 series, comprising the 761 power amplifier ($14,000) and 791 streaming preamplifier ($16,000), delivers a step up in performance and complexity. The flagships are the 861 power amplifier ($22,000) and 891 streaming preamplifier ($25,000), the latter of which is the subject of this review.

Scandinavia is home to many highly regarded audio companies, but most are located in Sweden and Denmark. Norway has just a few well-known makes, including Electrocompaniet, Hegel Music Systems, and SEAS. Hegel and Electrocompaniet are both active in electronics, while SEAS makes speaker drivers for speaker manufacturers.

Founded in 2020, Perlisten Audio is a relatively new entrant on the high-end audio scene. The firm was established by a team of industry veterans with the goal of manufacturing high-performing loudspeaker systems to rival the best at their price points. The first model was the S7t, a tall, four-way loudspeaker which utilizes several relatively small bass drivers to deliver satisfying bass extension in a slender design. Priced at around $20,000 per pair (all prices in USD), the S7t distinguished itself sufficiently well from the surrounding mass of competing designs to win several audio awards. From there, the firm has expanded its range to offer a wider range of options.

My father and his parents—my grandparents (obviously)—were kind, generous, inoffensive people. They wouldn’t say shit if they had a mouth full of it.
