Reviewers' Choice In today’s overcrowded hi-fi market, quality products can sometimes be difficult to identify among the many run-of-the-mill offerings. Every so often, though, an audio component is of such exceptional quality that it stands out. A few such outstanding performers can be found in digital audio, from brands such as Chord Electronics, dCS, MSB Technology, and EMM Labs, which eschew off-the-shelf DAC chips, choosing instead to develop their own DACs. The result? Some of the finest digital playback available today.

The world of fanciful, unlikely, unbelievable audio tweaks is constantly evolving. Over the years, we’ve had such outlandish concepts as the Beltist idea that wrapping your cold-water pipes with solder wire will improve the sound of your system, as will parking your car in the driveway facing out. Next came little dots that you place on your walls to . . . do something, I guess.

The power amplifier is the tough guy of the audio world. A good power amp is quiet, solid, and powerful. There are no moving parts in an amplifier. It does one thing only, and, if it’s a good one, it does that with grace, strength, and purpose. My martial-arts teacher, a quiet, solid, powerful Korean gentleman who’s now in his early 80s, says that while you can’t always tell who is tough by looks alone, it’s pretty damn easy to determine who isn’t tough.

They say it’s best not to meet your heroes, so I thought long and hard about how to approach this review. The Linn Sondek LP12 is arguably the most famous high-end turntable of all time. Its reputation as one of the most engaging and enjoyable high-end vinyl spinners has made it a legend the world over. Back in the late 1980s, when I was just 18 and putting my first system together for university, the LP12 and its archrival, the Michell GyroDec, were the two turntables I coveted most of all. Both were hopelessly beyond the reach of my student budget. So, they joined the Lotus Esprit Turbo and Kate Bush—in a dance leotard, staring wide-eyed at me—on my bedroom wall as examples of the things I most desired in life.

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.
