Hegel H30A
2 x 500w Power Amplifier or 1 x 1100w Mono Mode
With a power rating of more than 1,1 kW in 8 ohms, it is on the verge of being easier to measure the H30A in horsepower. The massive H30 mono power amplifiers from Hegel play any loudspeaker in the world with ease and authority. The H30 is our best power amplifier ever and is definitely a combatant for being the best power amplifier in the world. The H30A is developed as a monoblock, but there is also the possibility to use it as a stereo power amplifier to start with if you are on a budget. Progress is a one way street and so for our power amplifiers.
Normally, when you compare a less powerful amplifier with a more powerful amplifier, the most powerful will have a more potent bass, more attack and more "SLAM" than the less powerful one. This is how it works up to a certain point. The Hegel H30A is beyond this point, and all of a sudden the differences become different. The H30 will simply play with a completely undisputed control, regardless of the loudspeakers. The bass is tremendously deep, but not dominating. The level of detail in the high frequencies are unheard of, but never overbearing. Usually, a demo of the H30 and P30 combination ends with clapping hands and a whispering wooooow...
As a mono power amplifier, the H3A has a fully balanced output stage which reduces and cancels out distortion. Furthermore, the H30A has a much more advanced input stage and voltage gain stage. Both the H4SE and the H30 uses hand-matched transistors, but only the H30 uses the special combination of JFET and MOS-FET transistors. This further reduces higher-order harmonic distortion in the H30. The third big difference between the two is H30's output transistors. These are of higher quality, with less distortion than the ones in the H4SE. In addition to this, the use of dual transformers in the H30, reduces mechanical noise. The higher budget also allows the use of better parts throughout the H30.
Review by The Absolute Sound (USA)
"The Hegel H30A is not just a great-sounding amplifier, it's also a tremendous bargain. I know I'll get letters complaining that a $15k power amplifier by definition can't be a bargain. But what else can you all a 15,000 amplifier with massive output power, unflappable stability, and a gorgeous musical presentation that vaults it into a select league of world-class power amplifiers? If your amplifier budget is anywhere near $15k, the Hegel H30 should be on your short list of products to audition. You may find, as I did, that this unassuming and understated black box contains a Scandinavian surprise."
