The H30A power supply uses 2 separate 1000 VA toroidal transformers for fast response and
minimized transformer hum. With a power bank of 270,000 μF capacitors, the H30A can handle
even the most challenging piece of music at any volume, it always has enough power in reserve. On
the output stage we 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 we 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 we cancel out with our 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 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 we 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 our amplifier
technology. It is the large orchestra that brings life to any music in any venue.
