Heed Audio Obelisk Super Integrated Amplifier

Heed Audio Obelisk Super Integrated Amplifier

The icon

For decades the name Heed Obelisk was equal to a truly unique experience among the vast world of audio amplifiers. In some of these years Heed Audio offered two versions to choose from, with two different character. They are reviving the tradition and offering two versions again, and now the difference between the two Obelisk models are greater than ever before.

The Obelisk Super Integrated offers a more polished, a more immersive, and an effortlessly more impactful presentation. While the little brother highlights the essence of music with astonishing rhythm and instrument proportions, the Super Integrated displays the delicacy of the musical expression with a deeper focus on details.

There are many technical differences between the two amplifiers. A more powerful transformer is used, along with double amount of filtering and output capacitors, different power Darlingtons transistors and driver transistors, different auxiliary circuits, and all the time constants and biasing settings that are part of the Transcap tuning are changed for the Super Integrated. The two amplifiers have been meticulously tuned to reach perfection in their own world.

The Super integrated pushes the boundaries of what is normally expected as this price point.

SKILLFULLY HANDCRAFTED

Wherever possible Heed Audio use hand tools and manual labour to build their amplifiers, including the hand soldering of the PCBs. This is to ensure that every small component receives dedicated attention.

TRANSCAP TUNING

The Obelisk Super Integrated has 4 x 10.000 uF filtering and 2 x 10.000 uF output capacitors, paired with a custom audio grade 250 VA transformer. Heed selected the extra long life high performance Kemet ALC70 capacitor series for this amplifier. The current delivery and filtering options adjusted to be balanced, slightly to the ‘Charming’ side with fast transient response and enriched lower frequencies, as well as delicate and spacious atmosphere.

DISCRETE MM PHONO STAGE

Heed Audio mostly use discrete semiconductors in their amplifiers, including the MM phono section. This is a 2-stage active/passive RIAA preamplifier with excellent headroom and great compatibility with the majority of the MM cartridges.
