The Obelisk PM mono-bloc power amplifier is the main course of the Obelisk family. What is the ultimate Obelisk power amp like? How much can be extracted from capacitor-coupled power amp topology if done uncompromisingly, no holds barred?
Don’t be fooled by the PM’s deceptively modest power specification — 70W into 8 ohm, 120W into 4 ohm — as it hardly says anything about the real capability of this unit — a stable 150W delivery down to 2 ohm! And bearing in mind the unique Obelisk topology, those watts effectively behave more like valve-watts.
We’re satisfied that the Obelisk PM can drive virtually anything; even the most awkward loads can be handled with relative ease. Drawing on an enormous power supply featuring custom-made components and employing shorter signal paths than Heed have previously ever used in power amplification (signals are almost fed from component leg to leg) all these small engineering details contribute to astonishing performance results.
Sheer power and technical ingenuity are one thing (well, two…), musical performance is another, and one ideal which we hold above all others is summarized in our credo — ‘Forget Hi Fi — Remember Music’. The Obelisk PM is indeed that rare thing: a most unforgettable musical 'brute'.
If you really want to get maximum 'Heed-Room' into your system - and really want to feel how good Heed amplification can be within the framework of the Obelisk family, then pair the Obelisk PRE with a duo or quartet of PM's and let your music truly come alive. As Heed maintain..."It is simply one of the best power amplifiers we’ve ever built".
