Running Springs Audio Dmitri AC Power Conditioner

"The Dmitri is unique in my experience in that it not only doesn’t compress dynamics, but actually expands them. I heard this with the Dmitri powering just my front-end components, with the power amplifiers plugged into the wall outlets. (The equipment racks are at the back of the room connected to power amplifiers at the front of the room next to the loudspeakers, making it impossible to hear the entire system powered from the Dmitri.) Nonetheless, the Dmitri noticeably expanded dynamic scale and increased the sense of bottom-end heft and impact. Kick drum had more weight, body, and slam, and orchestral climaxes were more powerful. In addition to these sonically identifiable changes, music just seemed to have greater rhythmic coherence and flow with the Dmitri." - The Absolute Sound
