Heed Audio Obelisk Si-D MKIII

Legendary RC-coupled Integrated Stereo Amplifier (with Dactil 2.3 Card)
Manufacturer: Heed Audio

Description

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

After two decades of silence, Heed resurrected this legendary integrated, updating its exterior aesthetics and internal components. More importantly, however, Heed 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 Heed Obelisk Si has become a must-hear sensation straight out of the gate.

The Obelisk Si MKIII builds upon the award winning MKII (Best stereo amp £1000-£1500, What Hi-Fi? Awards 2012). It refines and hones the endearing drive and qualities of this highly regarded integrated amplifier. 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, the experts at Heed have found the solution that describes the magic it creates. Transcap technology is now the main path, which they pioneer and intend to follow, unaccompanied in the world.

The Obelisk Si MKIII is 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! This upgrade makes the Obelisk Si purr, and this has been reflected in the press - with What Hi-Fi? Sound & Vision (UK) remarking on the Obelisk si + Obelisk x2 :

"This is one of the most musically accomplished integrated amps we've heard anywhere near this price. Play something like Mama by Black Eyed Peas and the Heed charges along, making the most of the intricate rhythms and dynamic thrust. This unit sounds robust and in charge even when pushed hard. And it's enthusiastic without ever becoming overbearing."
"We like this amp a lot. Forget first impressions: this is a peach of a product."

The Obelisk Si MKIII features a remote control for volume (input switching is mechanical to preserve the best quality of sound) and has five analogue inputs for a selection of sources, and in true Heed fashion the Obelisk Si MKIII features an upgrade card system for some of their uniquely deft devices. The first input of this Obelisk Si has Heed's new, improved and extremely musically engaging Dactil 2.3 DA card (1x S/PDIF digital input) pre-fitted for enjoying the best from any digital sources 'out of the box'.

If you don’t like the many and more little boxes around you, this highly integrated system is your saviour.

Available in a black casing with black front.
