Heed Audio Obelisk PS

High Quality RC-coupled Stereo Power Amplifier for Obelisk PRE
Manufacturer: Heed Audio

Description

The Obelisk PS is a versatile stereo power amplifier, rated at 50 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.

But above all, the PS is every bit an Obelisk. It exemplifies Heed's long-standing tradition of eschewing DC-coupling for a less “processed” sound with more natural decay of tones and uncanny realism has reached new heights with the evolution of the Obelisk PS. With the capacitor-coupled power amp stage of the Obelisk Si integrated (even more effective when quasi-pre/power configured with the addition of the X-2 PSU), Heed have created a distinctively different sound signature much closer to the best of valve amplification than to conventional solid state presentation, as noted by many prominent hi-fi journalists:

"It is much closer to the ‘live’ magic of a reference-quality 300B than it really has any right to.” (Thierry Soveaux, Diapason).

"It really does make that solid-state valve-sound a little closer to reality.” (Jason Kennedy, Hi-Fi Choice).

"With its liveliness and ease it’s geared toward the intrinsic virtues of good valve amplifiers.” (Markus Sauer, Hi-Fi Statement).

The PS proves that it is possible to push the envelope of the Obelisk topology. In doing so, Heed have followed a simple path: They kept the proven dual-mono power amp circuit of the Si, improved its PCB layout, optimized all signal paths, opted for higher grade components, and upgraded the entire power supply. The result speaks for itself. The Obelisk PS, along with the PRE/Dactil and DT digital transport won Diapason D’Or 2009 and 6moons’ Best of The Year — Writers Favorite 2010.

Available in a black casing with black fascia, or black casing with white fascia.
