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, Heed has resurrected this legendary integrated, updating its exterior aesthetics and internal components. More importantly, however, they challenged themselves 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 the nature of RC-coupled amplifiers. By the designing of the current version of this amp,Heed has found the solution that describes the magic it creates. Transcap technology is now their main path, which they 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, Heed has worked out an upgrade card system for some of their 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 savior.
