hfnoutstandingInspired by 1980s behemoths, PS Audio's inaugural loudspeakers have a sound to match their striking looks

At a time when every new high-end product seems to come with an extensive backstory, the legend behind the 'aspen' FR30, the first speakers from Colorado-based PS Audio, still takes some beating. The £28,000-a-pair floorstanders have, we're told, been '50 years in the making', which places their beginnings just before that of the company itself, started by Paul McGowan and Stan Warren in 1973. In between times, McGowan left, worked with Arnie Nudell of Infinity Systems and then bought back the PS Audio name in the late 1990s, becoming its CEO. So we can safely assume that what is now realised as the aspen FR30 has been in the works for all that time.

hfnoutstandingThe final piece in PS Audio's quartet of innovative planar magnetic loudspeakers has arrived and it's quite the cutest of the range, but is it a wolf in sheep's clothing?

Even if the title isn't familiar, you'll know The March Of Progress by Rudolph Zallinger. Published in a 1965 volume of Life Nature Library and depicting 25 million years of human evolution as a series of side-on illustrations, from the ape-like Pliopithecus to modern man, it popped into my mind when I unboxed PS Audio's Aspen FR5.

If you haven’t heard of PSB before it’s not because the company is a young one – it was established as long ago as 1972, when founder Paul Barton was still at high school. But PSB’s products, well respected in its native Canada and elsewhere in North America, are only now coming to our attention in the UK, with the Armour Group (responsible for NAD and many other brands) having been appointed UK distributor. As an emissary, the Synchrony One is impressive even given that it is the most expensive speaker in this test. Almost as tall as the Pioneer but broader, it also features five drivers but in a three-way configuration: a 25mm titanium dome tweeter, 102mm cone midrange and no fewer than three 165mm bass drivers (effective diameter about 153mm) positioned at the top, middle and bottom of the cabinet.

Despite the small size, this well thought out design has much to commend it As the smallest and lightest speaker here, the Synchrony Two B may seem to be flying a kite in asking £1200 of its buyer. And, indeed, it is significantly cheaper in its native North America. But remember that its sibling, the large, floorstanding Synchrony One, won our group test in Aug ’09 – and take a look at the lab report. It may be diminutive but the Synchrony Two B walks tall: it has one of the flattest on-axis frequency responses here and a waterfall plot so clean that few more overtly prestigious speakers can match it.

From Switzerland, a compact phase corrected active speaker that reflects its pro background. But is it house trained? Although virtually unknown in the UK, PSI can trace its roots back to 1975, when founder Alain Roux first started manufacturing his own loudspeaker designs while still studying at the Lausanne École Polytechnique Fédérale. Over the past 35 years, this Swiss company has produced a range of custom, domestic, but mostly professional studio loudspeaker systems. In 1991 an analogue and digital electronics section was added to the acoustic laboratory at its Yverden manufacturing facility.

hfnoutstandingFlagship floorstander of Q Acoustics’ 3000c series leverages premier-range tech into a sub-£1000 enclosure

Employing a deal of trickle-down technology from its costlier models, the 3050c is the only floorstander in Q Acoustics’ new 3000c range. Following on from its popular 3000i series, the basics remain the same – slim speakers that look and sound good, with price tags that won’t break the bank. The 3050c tower tested here differs from the 3010c, 3020c and 3030c standmount models not only in size, but also with its dual 142mm woofer/mid units, promising bigger bass and more thrills at what seems an extremely generous £849 price tag.

hfnoutstandingThe Largest Of Q Acoustics' 5000 Series Speakers Combines Inspiration From The Concept 50 With Ideas Of Its Own

Armour Home's Q Acoustics has been busy in recent years, refreshing nearly its entire portfolio of passive and active loudspeakers, and expanding existing lines. The Concept 50 and 30 models were launched in 2022 to fill out its top-flight range, which includes the Karl-Heinz Fink-designed Concept 500 flagship , and a more affordable 5000 series appeared just before High End Munich in 2023. This didn't arrive fully complete either - the largest 5050 floorstander we're looking at here only finally debuted in the Spring of 2024.

Q Acoustics, established in 2006, is very much a new-wave brand that owes no philosophical allegiance to tradition, even if it is by definition a part of theentry-level British speaker scene. With the Concept 20, two elements combine to achieve noteworthiness – the cabinet technology and the optional stands. It goes without saying that the price alone (£350 for the speakers, or £550 for the package) automatically qualifies this as of exceptional value. The 655mm stands are handsome, well-made and clever – they lock to the speaker, hide the cables down the back, feature adjustable spikes, sound terrific and could probably sell by the truck-load on their own.

hfnoutstandingInspired by the flagship Concept 500, Q Acoustics' '50 packs a host of trickledown thinking into its slender frame

When Q Acoustics launched its Concept loudspeaker range in 2013, it began with a sub-£500 standmount – the Concept 20 [HFN Feb '14]. While this was in keeping with the value-for-money reputation the UK brand had developed since its arrival in 2006, within a few years it was reaching higher with the (then) £3000 Concept 300 and £4200 flagship Concept 500 [HFN Jul '17].

hfnoutstandingAs old as Hi-Fi News itself, Quad’s iconic full-range electrostatic stays fresh courtesy of new upgrades

Apocryphal it may be, but one of the lingering mysteries about Quad was why MD and chief designer Peter Walker never went ‘high-end’ with bigger amps or speakers. His answer was always that his amplifiers and speakers were ‘adequate for most needs’. While that’s true, one cannot deny the efforts of others to make Quad’s inaugural ESL go louder and deeper. So while the ESL 2912X may not be the cost-no-object/size-no-object electrostatic that some devotees of the brand might dream of, I wonder what Peter Walker would have made of the not inconsiderable £12,999 asking price?

In 1955 Wireless World published articles by Quad’s Peter Walker on the practical and theoretical aspects of making a full range electrostatic speaker. That year, he demonstrated two different prototypes developing one for the first public demonstration at the 1956 Audio Fair. Due credit must be given to Walker for the huge amount of pioneering work involved and the brave decision to make it a commercial product. When first introduced, a single ESL would have set you back £52, yet demand was far greater than supply.

hfnoutstandingQuad's first new speakers in some seven years feature an evolved version of the ribbon tweeter seen in its 'Corner Horn' of 70 years ago. Now, of course, they come in pairs!

For nearly nine years, I have been listening to Quad's ribbon-hybrid S-1 speaker – the brand's smallest two-way box-type system – as part of my day-to-day desktop set-up. When they were launched, I revelled in the realisation that they were a throwback to Quad's first ever loudspeaker, the Corner Ribbon of 1949, and the all-new Revela 1 tells you that the company's boffins, based in the UK and China, haven't been sitting idle since 2015.

hfnoutstandingBigger brother to the standmount two-way Revela 1, the three-way ’2 lifts Quad’s engineering into a floorstander

Quad’s Revela 1 is a classic two-way standmount offered at £1799 per pair minus supports, or £2498 if bought as a set. The floorstanding Revela 2 tested here sells for another £1k at £3499, complete with fitted, spiked plinth. The basic technology defines both speakers, but for the Revela 2 it has been doubled up and more. The test, then, is to discover how much extra that £1000 delivers...

The Aurum range arrives in the UK packed with bespoke technology This floorstander is no larger or more extravagantly equipped than many in this area of the market, but it is notably more substantial than the norm, at 31kg, and better finished too. Moreover, for a premium, there are numerous alternative finishes. Twin 170mm aluminium/ titanium/magnesium coned bass units work in parallel up to a specified 330Hz crossover and are reflex loaded by a single large rearfiring port. The distinctive slats we saw in the Titan VII are echoed in an array of vertical rubber cords that adorn the cut-out through which the recessed bass units radiate – in fact these appear to be part of the reflex/pressure chamber bass loading principle.

Innovative technology helps the Quadral stand out from the field A mere glance at the Platinum M4 is sufficient to identify it as a Quadral, the bass drivers recessed behind aluminium slats being a clear visual cue, whether the speaker carries the Quadral name or that of its prestige Aurum brand. It isn’t just a cosmetic feature but a part of Quadral’s enhanced form of reflex loading – there’s a large port at the rear of the cabinet – which really does perform differently if the relatively flat impedance curve is anything to judge by. A four-driver three-way, the Platinum M4 matches its twin metal-coned bass drivers to a similar metal-coned midrange unit, above which is not the ‘ribbon’ (actually leaf) tweeter we’re used to seeing in Aurum models but Quadral’s RiCom-M ring tweeter, which is unusual for its annular diaphragm being of titanium. Quadral claims that it produces character-free treble output with broad dispersion.
