in-akustik Referenz LS-4004 & LS-2404 AIR Pure Silver Loudspeaker Cables

Many years ago I bought a pair of speaker cables that retailed for about $550 at their prime but were heavily discounted “for a quick sale”. Despite that, at the time I still thought that I paid a lot (yes, I can be rather mean about some things Hi-Fi!). What I got for my money were (and still are) copper cables, while in-akustik’s Referenz (Reference) speaker cables reviewed here are made of silver. The connectors on my cables are gold-plated, which is great, while in-akustik connectors are plated with rhodium, a much tougher material that forms highly stable low resistance contacts. The list goes on, but to cut the long story short, Reference cables strive to deliver the best possible electrical parameters to your Hi-Fi system with very few – if any – compromises. And they look great!

Rogers LS3/5a Classic Loudspeakers

When, in the early 1970s, the engineering team at Britain’s BBC network was tasked with producing a small, dependable, accurate and consistent reference loudspeaker for outside broadcasting audio monitoring, the Dudley Harwood and Spencer Hughes-led team (later of Harbeth and Spendor respectively) produced the archetypal LS3/5. Subsequently, a modification to the original spawned the ‘A’ version which became, simultaneously, the classic and iconic LS3/5a, a superb design that also inspired many licenced versions by major British brands (one of these being Rogers). Its production ran for many years but the diminutive monitor has been in hibernation since the late 1990s. That is until the recent re-emergence of the Rogers brand under a new and dynamic leadership. With new engineering ideologies and in-house manufacturing, the new Rogers entity is now offering a revitalisation of both the iconic LS3/5a and LS5/9 BBC monitors. Here, we embrace the opportunity of scrutinising the classic LS3/5a Classic mini-monitor.

Magico A3 Loudspeakers

In the pursuit of the perfect loudspeaker design, audio engineers are faced with a number of imposing challenges. Obviously, careful thought must be devoted to the proper design of a driver complement, understanding the way in which those drivers, each manipulating or moving air within a given frequency range, will interact with one another in the final design. This complex interaction will in no small part also depend on the nature, components and execution of the crossover network and of course, the partnering or driving electronics (the amplifier) to which the speaker will be connected.

Cary Audio SLI-100 Integrated Amplifier

Austere, stark, unembellished… yet aesthetically truthful, functionally honest. They’re the terms which came to my mind as I unboxed the matter-of-fact SLI-100 integrated amplifier from Cary Audio. The design seems non-superfluous, stripped of excess and devoid of unnecessary decoration. But with a purposeful, regimented functionality to provide music. Does the SLI-100 deliver on its direct, straightforward promise?

Balanced Audio Technology VK-655SE Power Amplifier

The big, black BAT sat staring back at me with the same undeniable presence as “The Object” on the cover of Led Zeppelin’s album of the same name. The Editor had just left, having indeed delivered, as he had promised, “the flagship solid state Balanced Audio Technology amplifier”. Heeding the Call Up, we continued to eyeball each other as I scrounged around for another power cord to plug into its hulking, monolithic, dual mono chassis. The whole planet’s on fire, not least our sunburnt country right now, so what use did I have for all this grid-draining, solid-state fire-power?

Focal Sopra N° 2 Loudspeakers

Now celebrating its 40th anniversary, Focal was, originally, first and foremost a driver manufacturer. The company’s continual pursuit of excellence has meant investing heavily in R&D, along with state-of-the-art tools to test and evaluate its designs. Confirmation comes via its superb factory and facilities. Not surprisingly, when moving into designing complete speaker systems, the prevailing philosophy was to start with, and to perfect, the drivers first thus avoid the deleterious effects of complex crossover networks. As a result, Focal speakers are typically amplifier friendly and are therefore likely to perform consistently across a wide variety of equipment, giving the owner more freedom to enjoy their favored amplification. The Sopra range embodies the key technologies that Focal developed for its flagship Utopia range, but in a more compact and affordable package, allowing a wider audience to appreciate Focal’s signature sound. Here, we examine the mid-point in the penultimate range – the Sopra N° 2 loudspeakers.

McIntosh Laboratory MTI100 Integrated Turntable

I’ve never actually owned any McIntosh audio gear, but when I think of the brand the words ‘classic’ and ‘classy’ spring to mind, and in the case of their new MTI100 so does ‘cool’. As an audiophile, I’ve had positive experiences on occasions where I’ve heard McIntosh amplifiers powering speakers like B&W’s 800D and Sonus faber’s Amati Homage. From the moment I first laid eyes on the MTI100 in my local audio store, I’d been eager to review it – when companies like McIntosh, Linn and Naim turn their efforts to unique products such as this, new benchmarks are often set, the whole industry moves forward and everyone who listens to music benefits.

Hulgich Audio Duke Loudspeakers – Editor’s Follow-Up

Back in July 2019, our writer Tom Waters reviewed very favourably the impressively-built Duke loudspeakers from Australian manufacturer Hulgich Audio (read the review here). Prior to Tom getting the review samples delivered to his home, the Duke speakers had a three-week spell at SoundStage! Australia HQ. Over that period I evaluated the design’s engineering while inspecting, with deserved admiration, the substantial construction merits of Nicolas Hulgich’s and Swedish consulting designer Göran Niréus’ flagship creation. During that stint I also evaluated at length the considerable resolution powers of this tremendous design. Subsequently, Hulgich asked if I could provide him with a second opinion, with my findings meriting a ‘Follow-Up’ article… so here goes.

Harbeth Audio Compact 7ES-3 40th Anniversary Edition Loudspeakers

While the approach a designer adopts in the making of a loudspeaker may be different to piers from around the globe in terms of components used, differing priorities, construction methodologies, etc., the core engineering principles are a converging factor no matter the designer’s country of origin. Physics and electroacoustics laws are universal. Having said that, a designer’s own aural biases, his/her interpretation, may differ and therefore diverge a speaker’s sonic tuning, sometimes dramatically. This is far less so nowadays than a few decades ago when the ‘British’ and ‘American East/West Coast’ sounds were at discordant cross-purposes, splitting audio enthusiasts into tribal camps. Has British loudspeaker maker Harbeth Audio, with its new Compact 7ES-3 40th Anniversary Edition, made a valiant shot at bridging the divide between the analytical and the musical?
