“A genuine revelation at a price, after all, without competition” – Diapason





The range






Obelisk Si

integrated amplifier




There was a neat shoebox amplifier in the 1980’s which stirred emotions in unsuspecting hifi-freaks and music lovers alike. Sadly, the unbashedly different design of the original Ion Obelisk had become entirely forgotten. Well, almost entirely.


After two decades of silence, we have resurrected this legendary integrated, updating its exterior aesthetics and internal components. More importantly, however, we challenged ourselves with the demanding task of preserving the classic Obelisk’s absorbing delivery and infectious musicality, while offering even greater transparency, leading-edge detail and more gripping dynamics. Mission accomplished – the Obelisk Si has become a must-hear sensation straight out of the gate.

During the years of evolution, the Obelisk Si showed us the nature of RC-coupled amplifiers. By the designing of the current version of this amp, we have found the solution that describes the magic it creates. Transcap technology is now our main path, which we intend to follow, unaccompanied in the world.


The Obelisk Si III rated at a great healthy 50 watts per channel. Don’t be fooled by the kilowatt amps, this fifty is like a valve-amp fifty. And more, as a Transcap amplifier is rather different in this aspect. With this kind of power the Si is capable of astonishing dynamic authority and massive transients any time. Further on, there are the X2 or X4 power supplies, which converts the Si-system into a preamp/power amp combo with dual mono power amplifiers. Now that’s something classy!


To be more versatile, we have worked out an upgrade card system for some of our devices. The first input of the Si can be transformed into an MM phono input or an S/PDIF digital input via our upgrade cards. If you don’t like the many and more little boxes around you, this highly integrated system is your saviour.

Features

– 5 analogue inputs

– optional MM phono or DAC card

– upgradeable power supply (see Obelisk X2)

– Transcap technology

Obelisk X2

power supply




The Obelisk X-2 power supply (in fact, a dual-mono power amp PSU) holds the ante at a full 50wpc, while allowing the original on-board power supply of the Obelisk Si to dedicate itself entirely to its preamp section. In other words, with the addition of this single device, the Obelisk Si evolves into a fully-fledged dual-mono pre/power combination. It is a substantial technical upgrade, and consequently a leap forward in sonic performance: it catapults the single-box integrated Obelisk into a much higher league.


Features

– separate supply for Obelisk Si power stage

– dual mono supply rails

– enhanced power and impedance handling

Obelisk PX

power supply




One of the most difficult tasks we have undertaken has been to extend the capabilities of the Obelisk PRE, which was designed to perform beautifully as a self-contained unit. However, the Obelisk PX dedicated outboard power supply manages to surpass even our highest expectations.


The PX is based on a sophisticated fully-regulated, double-filtered circuit topology, which eliminates interference caused by the mains supply, providing the cleanest possible current to the PRE. It features very high grade components such as a high-quality mains transformer and well-sized high-grade capacitors custom made to Heed’s own specifications. This results in extremely low noise, low inner impedance and negligible distortion performance.


Although the PX is primarily designed to partner with the Obelisk PRE, it can also be paired to enhance the performance of our Quasar phono stage, Dactilus DAC, Canalot headphone amp, etc.


Features

– low noise, stabilized supply rails

– generously oversized components

– smart enhancement for the Obelisk PRE
