You might be surprised to see Leema launching a massive £20,000-plus amplifier combination now, hard on the heels of its lower-cost Pulse and Stream models. But as with everything this company does, there’s a logical progression. The Pyxis/Altair IV combination forms the heart of Leema’s long-considered reference series. ‘We needed to produce our reference system,’ says Mallory, ‘and from the outset it was always going to be monoblocks.

The Pyxis is a sturdy, handsomely-styled preamp which, in the best modern fashion, can be used with all manner of amplifi ers despite a plethora of Leema-only features. Pyxis provides both fully-balanced and single-ended analogue operation, with extensive custominstall/ home cinema-friendly settings and sockets. Its price is further ameliorated by the inclusion of digital ins and outs, including USB and S/PDIF in both directions, so the Pyxis is able to accommodate all of your digital sources and feed a computer for archiving. For another £500, the Pyxis can be supplied with an onboard phono section (based on Leema’s £3k Agena).

hfncommendedWith multiple inputs, streaming functionality and plenty of power, this elegant and compact system promises consummate convenience and super sound. Does it deliver?

Since 1993, Lindemann has been making distinctive products, all with an accent on design and technology. Although the company has also sold loudspeakers in its 27-year history, electronics have formed the staple of the product portfolio – and it has shown a particular interest in digital technology. The D680 of 2001, for example, was the first German SACD player, while the original Musicbook was an early example of a highly advanced streaming front-end [HFN Jun '14]. Lindemann's thinking has been eerily prescient, as other brands have since scrambled to get similarly elegant so-called 'style systems' into their ranges…

hfncommendedNow in mkII guise, Lindemann's network-attached DAC and analogue preamp sees a raft of internal updates and the promise of 'production secured for upcoming years'

Look at the latest iteration of Lindemann's network music player, the £3450 Musicbook Source II, and you'd be forgiven for thinking that nothing much has changed [HFN Jun '20]. This is still a compact unit, just 28cm wide and a mere 6.3cm tall, with nothing much on show save a power/standby button sunk into one end of the top-plate and an edge-mounted volume control, with a push-to-mute function, at the other.

With the C-600f preamp and the M-600A stereo power amplifiers, Luxman has delivered its interpretation of current generation solid-state excellence. The power amp offers balanced or single-ended operation, the option of converting it into a bridged monoblock of up to a specifi ed 120W/8ohm, plus a couple of neat touches on the back. Like all new Lux products, an indicator tells you with the press of a button if your mains polarity is correct. Another rear panel delight is a quartet of the largest speaker terminals I’ve ever seen, a nod to those who like tight terminals, but with an aperture for banana plugs.

hfnoutstandingContinuing its modern take on traditional Japanese purist amplification, Luxman finally offers a MM/MC phono/line preamp partner for its ultra-retro MQ-300 valve amplifier

Just over three years ago I had my first taste of cost-no-object Luxman [HFN Nov '16] in an achingly long time. The company has had its ups-and-downs, but fortunately its new owners – IAG, home to Quad, Wharfedale, Audiolab and Castle Acoustics – realise what a plum brand Luxman is, so it was expected that the flagship MQ-300 power amplifier which so charmed me would be followed by a worthy preamp. Enter the alluring CL-1000, at £16,000 a grand more than the power amp and looking every penny of its price.

hfncommendedLuxman has re-introduced what just may be the dream desktop rig, comprising the new NeoClassico CD player and tube integrated amplifier – or is it much more?

Can we agree that it's possible to love more than one system, as you would savour more than one type of whisky or wine? Masseto and Tignanello are simply not mutually exclusive. Luxman's re-imagined NeoClassico series is appropriately costly but not saddled with a 'high-end' price, so at £2500 for the D-N150 CD/DAC and £3000 for the SQ-N150 integrated amp, it is not an alternative to, nor a substitute for a high-end, high-power system. It is not out to usurp the role of your D'Agostino.

hfncommended.pngLuxman’s update of its fully-loaded, flagship headphone amplifier has resulted in the heavyweight P-750u – is this incarnation a contender for the best of the breed?

Decades on from the likes of the EarMax, AudioValve RKV and other pioneering headphone amps, born before cans became a ‘thing’, we are now spoiled for choice. Luxman, which has been on dazzling form of late, has upgraded its no-compromise champ to produce the P-750u, and it just may be the go-to unit if you’re 1) crazy for cans, 2) use various models and 3) love added fine-tuning control.

hfnoutstanding'Tubes Rule' is the Manley Labs mantra as we catch up with an aquatically-inspired pre/ monoblock combo that have been at the core of its range for the best part of 20 years

Timely or what? When editor PM pointed out that the Manley Jumbo Shrimp Line Preamplifier (£5849) and Mahi Monoblock Amplifier (a stereo pair at £7599 making up Mahi-Mahi – geddit?) had been in the catalogue for ages, I learned from company president EveAnna Manley that it was exactly 20 years to the day of their debut that I was auditioning the latter.

hfnoutstandingHere’s a traditional triode tube amplifier with a modern twist as Manley’s evergreen Neo-Classic 300B proves there’s more than enough power to energise your music

Are you the hands-on type who finds most power amps a bit boring because all they have is an on/off switch? Manley Laboratories’ Neo-Classic SE/PP 300B monoblock (£13,699 per pair) is the opposite: it lets you fine-tune the sound by fine-tuning the applied feedback.

hfnvintageClassic tubes meet modern tech in the £30,000 Project T-1 monoblocks. Is this Marantz's ultimate amplifier, asks an awestruck Ken Kessler

Contemplating the Project T-1 power amplifiers from Marantz, I realise that nothing in hi-fi should surprise us any more. If, in 1990, someone had told you that, by 1997, the hi-fi community would be clamouring for single-ended triodes and horn systems, that Quad and McIntosh and Marantz would reissue their valve classics, that Mobile Fidelity would open a new LP pressing plant and that Krell and Audio Research would introduce integrated amps, you'd have had that someone committed.

Martin Colloms hears the ultimate amplifier system from one of audio's elite names: the No26/No20.5 pre/power duo and No25 phono stage

Since acquiring the Mark Levinson Audio Systems company five years ago, Madrigal Labs has pursued an evolving research programme, generating improved circuits and product designs. The result is that current MLAS products now have an importance comparable with the original brand's landmark designs.

hfnoutstanding.pngThey may typify Stateside heavy-metal hi-fi, but this pre/power amplifier from one of the high-end's best-known names is really all about simplicity and directness

Depending on your point of view, what you see before you are either objects of absolute hi-fi aspiration or a symbol of everything that's wrong with high-end audio in the 21st century. Along with compatriot Krell, Mark Levinson is one of those names that's likely to be known even by those with only a passing interest in hi-fi and – though the marque has undergone several twists and turns in its near-50-year history – it remains one of the best-known in the audio business.

At last, Levinson’s flagship No53 monoblock amplifiers [see HFN Jan ’11] now have a Reference-status preamplifier with which they may be rightly partnered. The No52 is a two-chassis component designed with meticulous attention to detail both in its topology and in features that offer comprehensive system configurability. The rationale of this approach is to isolate the pure analogue audio circuitry from any possible source of pollution: it physically separates the power supply and microprocessor-driven controls from the audio electronics contained in the larger chassis. Volume control is via a precision ladder resistor network with fine gain adjustment in 0.

The latest Levinson product is a consummate music maker New electronics bearing the Mark Levinson badge don’t appear too often. When they do, the world of high-end audio expects them to be exemplary. In producing its first switching amplifier, the ML design team has been able to scale things down to (almost) manageable proportions. The benefits of Class D amplifiers include increased efficiency enabling greater power output while requiring less heat dissipation in smaller, lighter and more affordable packages.
