The Hegel H30A power amplifier replaces the H30 reference power amplifier that has been on the market since 2011.
For several years Hegel have known that the H30 was living on borrowed time because the extremely good transistors they used were being discontinued.
This was a problem because they were so good that finding something that could even come close proved to be very hard.
So, for years Hegel have been looking for replacements that could not only match, but also improve upon the performance of their power amplifier.
They have been testing and listening and testing again, and finally are able to launch their new reference power amplifier.
With a new design and vastly upgraded sound qualities, the H30A sets a new bar for what Hegel power amplifiers can achieve.
They of course work best together, but both can also be great individual upgrades to existing systems.
Speaking of upgradability, the H30A is designed as a mono power amplifier and performs best when used as such.
Hegel do however realise that some do not need that much power, and some want to try one before going for the full package.
That is why the H30A can also be used as in stereo mode.
The Hegel H30A is The Orchestra.
With its immense power, speaker matching is no longer an issue.
The Orchestra can play any “venue”, be it large stadiums or small cellar clubs, and with its unsurpassed skill and attention to detail, no music is too challenging It conveys all music like you never thought possible.
No matter what or where it plays, The Orchestra will always perform at its best.
The Hegel H30A is their reference power amplifier.
Hegel have nicknamed it The Orchestra because that is what it is.
The H30A’s job is to take command of any music on any speakers and make it sound as good as possible without ever breaking a sweat, and they can think of no more challenging music than a large orchestral piece.
The H30A is an absolute powerhouse of an amplifier
In its mono state it delivers a truly astounding 1100 watts in 8 ohms, and it is completely stable even with 1-ohm loads.
To achieve this, they have applied all their skill and knowledge in amplifier design and combined that with the best electronics.
The H30A power supply uses 2 separate 1000 VA toroidal transformers for fast response and minimised transformer hum.
With a power bank of 270,000 μF capacitors, the Hegel H30A can handle even the most challenging piece of music at any volume, it always has enough power in reserve.
On the output stage they use 56 pieces 15A 200W high speed, ultra-low distortion bipolar transistors.
With so much power ready at any given time, things like speaker sensitivity and variation in loads no longer come into play.
With the H30A you can confidently drive any speaker you like.
Power is however nothing without the details to match.
In a large power amplifier like this, the input stage is especially vulnerable to electrical interference distorting the music signal.
One troublesome type of distortion is higher order harmonic distortion.
It is a type of distortion that is far removed from the original music frequencies and can often make the amplifier sound harsh and unmusical.
In the H30A input stage they eliminate this by using single pair FET transistors.
These are carefully hand matched transistors that have the exact same values, and therefore they have no higher order harmonic distortion.
Other types of distortion they cancel out with their patented Sound Engine technology.
This actively monitors the music signal for corruptions and corrects for distortion using a feed forward design.
Sound Engine effectively removes distortion in real time as the signal is amplified.
These measures make the H30A sound very smooth and natural, without compromising on the details.
The Hegel H30A is designed as a mono power amplifier, but it can also be used as a stereo power amplifier.
It has both balanced (XLR) and unbalanced (RCA) inputs and a 12V trigger input.
For the best possible connection, the H30A features high quality, gold-plated speaker binding posts.
Usually, when going from one amplifier to a more powerful one, you experience more of everything.
More bass, more details, more involvement everything is just more.
With the H30A they have reached a whole new level of differences.
Because the H30A is so immensely powerful and detailed, the concept of “more” simply becomes irrelevant .
In the H30A the bass is tremendously deep , but never dominating.
The high frequencies are exceptionally detailed, but never fatiguing.
And the articulation of vocals in the midrange is just sublime.
At this level, what you experience is simply total control.
The H30A is an amplifier that can drive virtually all known loudspeakers with authority and ease.
It never sounds forced, only relaxed and musical.
The H30A is the spearhead of their amplifier technology.
It is the large orchestra that brings life to any music in any venue.
