Heed Audio Obelisk PS Stereo Power Amplifier


The Obelisk 'ps' is a versatile stereo power amplifier, rated at 60 watts per channel into 8 Ohms, yet performing like a much higher rated amplifier due to its unique circuit topology and outstanding power supply section. It is entirely suitable for bi-amping, tri-amping or multi-room use. It is a perfect match for the Obelisk 'pre'. Above all, the 'ps' is every bit an Obelisk. Our long-standing tradition of eschewing DC-coupling for a less "processed" sound with a more natural decay of tones and uncanny realism has reached new heights with the evolution of the Obelisk 'ps'.

The Obelisk 'ps' proves that it is possible to push the envelope of the Obelisk topology. In doing so, we followed a simple path: we kept the proven dual-mono power amp circuit of the Obelisk 'si', improved its PCB layout, optimised all signal paths, opted for higher grade components sourced from the likes of Mundorf, Clarity Caps and Noratel, and upgraded the entire power supply. The result speaks for itself. The Obelisk 'ps', along with the 'pre'+'dactil' and Obelisk 'dt' digital transport won Diapason D'Or 2009 and 6moons' Best of The Year — Writers Favorite 2010.
