Pre/Power Amplifiers

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.

At last, an output transformerless tube amplifier that needn't play second fiddle to transistors, says Ken Kessler, as he hears the GM 200

Given that few people will defend tube/transistor hybrids, how do you go about satisfying the valve-oriented consumer who wants his or her amp to have everything under one cage? And without simply adding to the buttonry? Italian company GRAAF (Gruppo Richerche Audio Alta Fidelta) has as its slogan 'II Suono Fatto A Mano', which I think translates into 'Hand-Made Sound'. This is about as cool a way of saying 'Lunatic purism' as I can imagine.

Celebrating a legacy that stretches back 50 years, the Norwegian brand stamps its authority with the heavyweight AW 800 M flagship amplifier – a solid cube of power!

There's a classical simplicity about this flagship pre/power amplifier combination from Electrocompaniet. The style – realised here with clear-on-black acrylic fascias with gold detailing – harks back to its first amp, 'The 2 Channel Audio Amplifier' [HFN Dec '11], based on Dr Matti Otala's tackling of 'Transient Intermodulation (TIM)' distortion, shortly after it began operations in 1973.

This Polish tech brand has already made waves with its OOR headphone amp and DAC-equipped ERCO. Now comes its most sophisticated digital offering yet – the Wandla

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.

Taking inspiration from the industrial design and key circuit features of D'Agostino's Momentum series, this second-gen Progression amplifier may upset its own applecart

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.

Dubbed 'The Conductor' and 'The Orchestra', respectively, Hegel's replacements for the decade-old P30/H30 pre/power amplifiers are flagships worthy of their names

By all accounts Hegel has been very busy over the last few years, which is a notion that might raise some eyebrows because – understandably – the Norwegian company went a little quiet during and after 2020. In fact, the V10 phono preamplifier [HFN Mar '21] has been about the only piece of hardware to escape the drawing board of Hegel's owner and master engineer Bent Holter since Covid. However, as industry insiders and the company's user base well knew, Hegel was battling the angry gods of software development to make its major integrated amplifiers Roon Ready.

The original Halcro amp starred in a recent HFN Vault feature but, some 20 years on, the marque is back in the same iconic shape and with the same high tech claims...

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!
