Heed Obelisk X-2 Power Supply Upgrade for Obelisk Si

Heed Obelisk X-2 Power Supply Upgrade for Obelisk Si


The Obelisk X-2 power supply (in fact, a dual-mono power amp PSU) ups the Obelisk to a full 50 w/ch (again, behaving more like so many valve-watts), while allowing the original on-board power supply to dedicate itself en- tirely to the preamp section. In other words, with the addition of this single device, the Obelisk Si evolves into a fully-fledged dual-mono pre/power combination. The transformation in sound quality is dramatic. Bass becomes hugely more authorative-- deeper and tighter-- and dynamics take a huge leap forward.
