Heed Audio's cObelisk Si has become a must-hear sensation straight out of the gate. Preserving the classic Obelisk’s absorbing delivery and infectious musicality, while offering even greater transparency, leading-edge detail and more gripping dynamics. 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. With this kind of power the Si is capable of astonishing dynamic authority and massive transients any time.
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. 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.
