Who doesn’t love a tube amp? Okay, okay; I know there’s a large contingent of audiophiles who actively don’t like them, but those people are missing an important part of their souls. Tube amplifiers check many of the boxes that define archetypal human satisfaction. Think about it—tube amps provide warmth and light. They rely on similar principles to the lightning in the sky—which we used to think was the work of the gods.

Please note: the Devialet Astra is still being tested in our lab, so check back for the measurements.

The late Wallis Simpson, Duchess of Windsor, famously declared, “You can never be too rich or too thin.” French manufacturer Devialet appears to have taken the latter half of this maxim to heart in the design of their amplifiers. Their first product, the D‑Premier integrated amp (2010), stood just 1.7″ high and marked a striking departure from conventional amplifier design. It caused a sensation at the 2011 Consumer Electronics Show in Las Vegas, where it was shown with its innards exposed, underscoring its unconventional engineering approach.

Reviewers' Choice It seems these days I begin my reviews with an account of how the component arrived in my living room. I won’t do that here. Instead, I’ll refer you to (a) my March 2026 editorial, where I explain why I’m sitting in my neighbor’s house listening to the PMC MB2 SE speakers, and (b) the My Audiophile Neighborhood episode detailing how we set up these monstrous, wonderful speakers, and how the review came about. Just for good measure, here’s a link to my account of my first mind-blowing exposure to PMC’s sound-reinforcement demonstration over on Soundstage! Global.

I’m not often surprised at hi‑fi shows. I hear so much equipment, in so many different combinations, throughout so many different rooms that I find myself becoming jaded. It takes something truly unique to jolt me out of my comfort zone.

Truly new concepts are extremely rare in audio. Generally, new ideas aren’t welcome, unless they manage to develop some sort of inorganic viral buzz. And wildly different topologies are looked on with active suspicion. I wish this weren’t the case, but audiophiles tend to be a stodgy lot.

J.A. Michell Engineering is one of England’s most respected turntable manufacturers. Thankfully, Michell has remained a family-owned concern that doesn’t need to answer to overseas conglomerates, venture capitalists, or outside investors. The managing director, Jonathan Nye, is married to the granddaughter of founder John Michell. Recently, the company has rebranded and released a swathe of new products, including the all-new Gyro and Revolv turntables, plus the exquisite Apollo phono preamplifier I reviewed for this site in January.

The German audio manufacturer Burmester Audiosysteme writes that their guiding philosophy is “perfection and perpetuity in sound and design.” That means they want to get things right, and they want to ensure their products do not wear out or become obsolete. As a result, they take their time developing new products, and then they keep them in production for a very long time.

The Townshend Audio Allegri Reference is certainly the most unusual preamplifier I have ever reviewed. It may surprise you to know that Max Townshend considered the Allegri to be his greatest achievement, rather than his legendary Rock turntable or pioneering work on acoustic isolation.

It was sometime around 2004. I’d been flailing around trying to find an appropriate replacement for my aging EAR Yoshino 509 mono tube amplifiers. The EARs had become unreliable to the point where I could no longer trust them in my reference system. Looking for reliability and neutrality, I purchased a Musical Fidelity A300cr amp, and that worked well for a year or so, but I was missing something. After reviewing the Anthem P2 Statement one year later, I ended up buying the review sample, hoping that I’d find peace with this large, powerful solid-state amplifier.

J.A. Michell Engineering Ltd. is one of the longest-established family-owned audio firms in the UK. Their GyroDec turntable, which I have used as my reference for 26 years, is a bona-fide cult classic and one of the very few bargains in high-end audio. You can buy one new with a standard tonearm and cartridge for under £5000. Even in its most basic form, it’s a serious vinyl spinner, but the real benefit of the GyroDec is its ability to take advantage of more potent ancillaries. Mine is fitted with an SME Series IV tonearm and a Lyra Kleos SL cartridge. The current price of my rig is north of £12,000, but it has outclassed some exotic turntables costing up to £25,000.
