Pre/Power Amplifiers

Does the world really need another DAC? Considering the ample offerings from traditional and emerging Asian hi-fi brands, you might be tempted to say, 'not really'. However, Poland's Ferrum Audio combines experience with a flair for innovation – its parent company HEM has been an OEM contractor for other manufacturers, possibly inciting its engineers to go one better for their own brand.

It struck me, around halfway through the first track, that designer/CEO Dan D'Agostino was emulating the way supercar companies delineate their model ranges. Hey, I needed something to explain why the new Progression S350 Stereo power amplifier at £34,998 costs just over half that of the Momentum S250 MxV's £54,998, and yet it is over two times the size and rated at 100W more per channel: 350W vs 250W. Also, at 454x230x584mm (whd) against a Momentum's 318x133x546mm, the Progression S350 dwarfs the dearer unit. It was like the comedy Twins, with Schwarzenegger standing next to DeVito.

Working out the brand behind the Eclipse Stereo power amplifier isn't hard: not only is the design a modern take on the iconic Australian Halcro amps of the past [see 'From the Vault', HFN Dec '22], but the product itself, with the power supply and amplifier suspended between two solid uprights, forms the letter 'H' – not a trick we've seen other manufacturers attempting!

It's not unusual to find consumer hi-fi hardware making some concessions to the custom installation (CI) space – typically connectivity, such as RS232 and Ethernet – that enables a CI professional to integrate and control the product in a wider system. Yet there are also items, such as McIntosh's MI502, that are more deliberately aimed at the CI market. A slimline two-channel power amplifier, it looks a world away from some of the Binghamton, New York-based company's heavy-hitters. Should it be given a swerve by the dedicated audiophile? Or might it be just what the doctor ordered?

Hands up those who have seen a Bryan amplifier before, let alone heard one. Me neither – until I unpacked the Mark III Model 500/700 pairing seen here. The first 500 arrived when higher-power transistors were beginning to be used in quality audio, yet while the technology became universal, British brand Bryan sank without trace.

Musical Fidelity is no stranger to big power amplifiers. Its top-of-the-range monoblock, the £3599 M8s-700m, claims a 700W/8ohm output and weighs in at 35.5kg, and the company sells a stereo model in the M8 series too, the £3999 2x500W/8ohm-rated M8s-500s. But perhaps what few expected from the brand, considering its range also consists of DACs, streaming amps, phono stages and CD players – everything a two-channel audiophile could want, in other words – is a seven-channel amplifier. Which is what we have here, in the shape of the M6x 250.7.

Who remembers the Stella Artois ad that proclaimed its lager was 'reassuringly expensive'? A slightly odd slogan, if you ask me, but it came to mind when setting up Exposure's 3510 pre/power pairing, only substituting the word 'expensive' for 'simple'. Here are two hi-fi products where simplicity has been elevated almost to an art form, reflected in the casework, choice of connections and user experience. And at £1590 a piece, these recently launched models aren't outrageously expensive.
