Hegel H120 streaming integrated amplifier Review

What motivates music lovers to look around for a new Test streaming integrated amplifier hagal? Some say they are missing an important feature on their current device – a streaming client, for example. The others that a new amp should bring them even more intense sound experiences – for example with unusual technology. The Hegel H120 integrated amplifier presented here attracts both groups of buyers to the hi-fi dealer. For one, it has an integrated, Roon-enabled streamer. On the other hand, thanks to unusual, patented circuit technology, it promises exceptional sound quality.

In the integrated amplifier lineup of the Norwegian hi-fi specialist Hegel, the H120 replaces its direct predecessor Hegel Röst. Like this, the H120 also has a nominal output power of 2 x 75 watts at 8 ohms. Of course, the H120 wouldn’t be from Hegel if it didn’t look just like its predecessor. After all, as the “family photo” in the gallery below shows, none of the Hegel amps ever built can deny their lineage. It is, therefore, a matter of honor that the Hegel H120 is also available in a black-and-white finish.

Also in the best Hegel tradition, the H120 is extremely solidly built and has excellent workmanship. Its housing is made of robust sheet steel, while the convex curved front panel is made of a solid piece of aluminum. The included infrared remote control also has a high haptic quality. The tiny buttons on its surface are more a matter of taste. After all, they offer a noticeable pressure point.

The company philosophy is interesting, which Hegel Vice Anders Ertzeid sums up as follows: “We leave out every component that is not conducive to the sound.” The fact that the Hegel H120 rests on three feet is therefore not a statement in the Meaning: “Three feet sound better than four”. Rather, “Three feet don’t sound any worse than four.” The Hegel H120 also demonstrates this reduction to the essentials in other areas.

Basis – the Hegel SoundEngine

The distinctive feature of all Hegel amps is their special circuit technology, called “SoundEngine”. It is implemented in its latest generation in the H120. Compared to the original patent by Hegel mastermind Bent Holter from 2001, there are some not entirely unimportant changes here.

The way SoundEngine works is particularly clear in comparison to conventional analog amplifiers. Negative feedback plays a key role here – the common panacea for improving almost all amplifier properties. This usually takes the form of so-called overall negative feedback for the respective amplifier assembly (phono stage, pre-amp, power amplifier). The negative feedback loop usually contains several amplifying elements (transistors, tubes).

On the other hand, the circuit technology of the Hegel amps works differently. Similar to the anti-noise principle in noise-canceling headphones, SoundEngine causes a “subtractive distortion compensation”. The principle behind it: If you subtract the input signal of an amplifier stage from its output signal (reduced by the gain factor), you get the signal distortions generated in this stage as the difference. If this difference signal is then added to the output signal again with an inverted phase position, the distortion components that occur are – at least theoretically – completely eliminated.

Whether static or dynamic – due to the principle of this method it is largely irrelevant how the signal distortions come about. It is therefore also suitable for particularly critical amplifier elements – for example, the push-pull output stages with their typical crossover distortion. In my opinion, this is where the greatest potential of Hegel’s SoundEngine lies. Because it does not inherently require overall negative feedback, the load and control current circuits in the amplifier can act independently of one another. This means that the counter-EMF coming from the loudspeaker cannot have any repercussions on the sensitive input stages.

This is supported by the fact that the load and control circuits each have their own power supplies, including separate transformers. This technology is called DualPower in Hegel jargon. It goes without saying that it can also be found in the H120.

digital

A major incentive to buy the new Hegel H120 is undoubtedly its Roon-compatible streaming client. At the time of the test, the network-based integration as a Roon device was only possible via the Airplay protocol. However, Anders Ertzeid was recently informed that a corresponding firmware update to the uncompromising Roon transmission protocol RAAT is already on the landing approach.

Until then, however, the streaming client in the Hegel H120 need not remain unused. As a UPnP-capable device, it can play music from any DLNA-compatible NAS – in the simplest case, from a USB stick plugged into an AVM FritzBox. The already mentioned airplay and Spotify Connect are also on the schedule. However, the following applies to all of them: Network integration via Ethernet cable is mandatory – for reasons of quality, neither WLAN nor Bluetooth is “transmitted”.

Are apps useful for the sound? Not really – that’s why Hegel does without one of his own. Rather, this “playing field” is left to specialists who have been making their mark here for many years – for example, JRiver Remote, PlugPlayer, or BubbleUPnP.

The D/A converter department of the Hegel H120 has been thoroughly revised compared to the Röst – of course in line with Hegel’s reduction philosophy. Computer USB yes – but not at any price: After all, there is the streaming client for unrestricted Hi-Res playback. That’s why you can safely entrust the USB connection to the Tenor TE7022 interface module, which is no longer brand new. As is well known, it sounds good and requires no driver installation (USB 2 Class Compliant), but only allows sampling rates up to a maximum of 96 kilohertz.

The Norwegians invested the budget saved with the USB input in the new D/A converter chip, which it benefits all digital sound sources. Like many of its competitors, the Hegel H120 now relies on the AKM AK4490.

Hegel H120 – practical sense

Despite Hegel’s philosophy of reduction, the H120 impresses in everyday use with some clever detailed solutions. For example, the volume control for any of the three analog inputs can be programmed to a fixed maximum value. This enables easy integration into home cinema systems. Furthermore, you can specify the volume setpoint value that applies when switching on, which prevents nasty surprises.

Another great thing is the option of importing firmware updates directly from the setup menu via the Internet (…which hopefully will bring us the Roon update soon). Last but not least: Thanks to its preamplifier output, the Hegel H120 can even control external power amplifiers, which makes it suitable for bi-amping.

The Hegel H120 in a listening test

Some semiconductor amplifiers need half a day to warm up after being switched on in order to fully develop their sound potential. The Hegel H120, on the other hand, was “fully there” after just a few minutes. It probably owes this to the Hegel SoundEngine: Apparently, its subtractive distortion correction means that its power amplifiers react much less critically to temperature-related quiescent current influences.

The next surprise for me was the rediscovery of the now 30-year-old NAD-3020 phenomenon. It’s hard to believe how grippingly dynamic music reproduction can be even with a moderate power level of the amplifier. To put it another way: Even with loudspeakers like the Canton A 55, the Hegel H120 had no problems driving the right thrust waves through the listening room with pulsating tracks like Rykketid by Trentemøller. The listening test time invested by the Hegel team in selecting a number of mains transformers was therefore definitely worth it.

In terms of its basic character, the Hegel H120 is one of the agile, lively amplifiers, without appearing brighter in the midrange and presence range. This was also confirmed by the listening comparison with the Neukomm CPA1155S exceptional integrated amplifier. The Hegel H120 even managed the AB comparison with the Swiss, which was almost three times more expensive, surprisingly confidently. Not just in terms of tonality and dynamics, but also in “musical” disciplines such as inner drama – which can be heard very well, for example, in Scroobius Pip’s suspenseful “Broken Promise”.

The clear sound character of the H120 was by no means accompanied by an undercooled note. Rather, it was the far-reaching spectrum, which made his ability to articulate. In this respect, the sales marriage between Hegel and KEF is a pretty happy one: the Norwegian perfectly accommodates the distinguished high-frequency reproduction of a KEF R3, for example, with its tuning. So it’s not surprising that Anders Ertzeid used a pair of KEF Blade Two speakers when presenting the H120, which he calls “Baby Giant”.

Also fully digital

In view of the great sound performance as an analog integrated amplifier, it is gratifying that the D/A converter department in the Hegel H120 played up to par. The listening comparison with the Questyle CAS192D Golden Series , which feeds in via an analog input, revealed subtle differences: The golden boy from the Far East, which costs at least 3,000 euros, performed a little more decisively in terms of dynamics and also showed slightly more plastic tones. However, these differences were not substantial.

However, the streaming client had a botched premiere. At least the prelude in Roon Airplay mode flopped thoroughly: the music sounded flat, concentrated in the acoustic center, and lost all its magic as a result. However, there was a sigh of relief again in DLNA mode: Here the H120 showed itself again in its usual form. According to Hegel, the sound quality in DLNA operation can even be increased slightly with the currently available firmware update.

Hegel H120 – Conclusion

Everything important is concentrated in one device, fantastic sound, stylish design, easy operation, and attractive price – the Hegel H120 is the perfect device for today’s passionate music lovers.

Its technical concept seems minimalistic and audiophile, but it is extremely well thought out and down-to-earth. No feature battle, no pandering with unnecessary gimmicks – all this makes the Hegel H120 a “real guy”. The only thing missing to be an absolute hit is the “Roon Ready” logo, which we hope will be granted soon. LowBeats stay tuned…
