Pre/Power Amplifiers

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.

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.

Search online and you’ll discover a groundswell of cheap DACs and streamers playing to every (hardware) whim, making it easy to overlook Eversolo’s efforts. But the company, which is the dedicated audio department of Shenzhen-based Zidoo, known for its EISA Award-winning Neo S media player, follows a different, more quality-focused strategy, as the affordable Z8 DAC and DMP-A6 have so far proved.

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.

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.

Here's a fun game to play: look through the product catalogue of US manufacturer Balanced Audio Technology and try to spot the odd one out. It should only take you a matter of seconds because all of its current models, bar one, employ tubes in either their power or preamp stages. And if you still haven't realised I'm talking about the new REX 500 power amplifier, it's the one that's roughly twice as big as all the others.

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.
