The review of the Sablon Audio Gran Corona AC power cord has just gone live at Positive Feedback Online here. Here's a couple of snippets from the review to entice you:

"It is clear that the Sablon Audio Gran Corona AC power cord designed by Mark Coles is a tour de force in power cord design, and I preferred the Gran Corona on my Sophia Electric 91-01 300B mono amplifiers and the Leben RS-100 line amplifier by quite a margin to both the Sablon Audio Robusto and Acoustic Revive Power Reference, and in that order.

The Gran Corona had a combination of sonic prowess and overall musicality that really impressed me, creating a musically evocative and emotionally charged listening experience that once heard is quite addictive and memorable. Overall the Gran Corona is still a touch to the warm and dark side of neutral, yet it provides incredible transparency and detail recovery, deeply infused tonal colors, accurate timbral signatures, and state-of-art performance on attributes important to audiophiles like imaging, soundstaging, dynamics, and soundspace reproduction."

 'The bottom line is this: prepare to be impressed, as the Sablon Audio Gran Corona is the real deal. The Gran Corona incorporates every technological refinement extant into its tour de force design. In a hand assembled, labor and tweak intensive process, Mark, through very careful and astute listening, has created in the Gran Corona a superbly musical and sonically spectacular AC power cord. The Gran Corona unfailingly delivered a musically evocative and emotionally charged listening experience that I enjoyed coming back to time and time again. A smokin' hot Gran Corona—way to go Mark!"

Enjoy!
