Pre/Power Amplifiers

Powerful, but trading subtlety and musical sensitivity over brute force, Ed Meitner’s flagship MTRS stereo power amplifier finds its perfect partner in the all-analogue PRE

The promotional literature for EMM Labs’ MTRS stereo power amplifier is so sure of its designer’s cachet within the audiophile community that it simply refers to him as Ed. For those not in the know, Ed is Ed Meitner, founder of Canada’s EMM Labs, and – back in the day – the engineer tasked by Sony and Philips to help with the development of SACD. The company that bears his initials operates in the high-end (there’s a more ‘accessible’ Meitner Audio brand) and maintains a boutique separates catalogue.

The hi-fi world’s most powerful amplifier – the aptly named Relentless – has spawned two new offspring, but the ‘baby brother’ of the duo still weighs in at 145kg apiece

Lame analogies – both banal and obvious – spring to mind when one is directed to review an amplifier which is a little over half the power of its predecessor. One thinks of cars offered with engines of half the horsepower of a dearer sibling, of second growth wines, and other half-pint offerings. But the D’Agostino Relentless 800 Mono Amplifier – a heady £236,000 per pair – delivers the wattage that provides its model name: 800W per chassis. And that is conservative.

Hailing from the shores of Lake Constance in Germany, Violectric offers a wide range of headphone and combined DAC/headphone preamps. We dip our toes into its waters...

The Violectric name may be new to you, as it was to me, but behind the brand is a company getting on for four decades in business, principally in the pro audio field, where it operates under the rather unusual moniker of Lake People – inspired by the company’s location in the Lake Constance region of Germany. Like many an audio brand from that country, the company designs and manufactures its products in-house, and is proud of the ‘Made in Germany’ label.

Inspired by Leema Acoustics' flagship Constellation series, this pre/power combination is the first fruit of the Welsh brand's new Quantum range. Does the Graviton have gravitas?

The tone of the announcement of the new Leema Acoustics Quantum range has the air of a Hollywood blockbuster: '25 years in the making…' it begins. But perhaps this hyperbole can be forgiven as this is the Welsh company's first new range in more than ten years and sees the technology of its flagship lineup simplified to reach more affordable prices. Here we have the first two Quantum arrivals, both available in silver or black – the Neutron preamp, with 13 inputs including a built-in DAC, is £1500, as is the Graviton stereo power amp, rated at 150W/8ohm. Buy the two together and you save £200, bringing the package price down to £2800.

Rising phoenix-like from the ashes of Deltec Precision Audio in 1992, the 'continuity brand' DPA retained designer Robert Watts' flair for innovation. How does it fare today?

The story of DPA is not uncommon among small and specialised hi-fi manufacturers. Arriving in 1992, it actually represented the second iteration of a company co-founded by Robert Watts (who has since gone on to be digital design consultant at Chord Electronics). And while Deltec Precision Audio, which debuted in 1984 with its CTA80 preamplifier, had ultimately shut up shop in the early '90s, the ideas behind its original models clearly had some merit – it was soon back with Watts onboard, albeit under a slightly different name.

Taking both aesthetic and design cues from the flagship 159 monoblocks, the 218 power amp is the German marque's newest model, teamed here with the 077 preamp

Never accuse Berlin-based Burmester of timidity... In an interview published to mark the launch of its 216 and 218 power amplifiers, its Team Leader for Quality Management, Thomas Schneider, says, 'We have thought in exactly the right direction'. The 216 amplifier is part of what the company calls its Top Line, and while the 218 may look similar it's actually in the upper tier Reference Line, one step below the Signature Line that features the flagship 159 monoblocks and near-2m-tall BC350 speakers, yours for £233,000 a pair.

Built into an enhanced H590 chassis but featuring 'sound tuning' from the P30A/H30A pre/power, Hegel's fully-networked flagship integrated gets off to a flying start

After an extended period of Covid and component shortage-related calm, Oslo-based Hegel has seemingly shifted into overdrive, launching multiple new products in just half a year. First up in 2023 was a major update to its flagship pre/power system in the form of the P30A and H30A [HFN Jun '23], followed by the Viking CD player [HFN Sep '23]. The third act is the launch of the H600, which takes over from Hegel's popular, top-tier H590 integrated streaming amp, and sells for £10,500 in a very dark grey, almost matt black finish.
