...Grounded or Ungrounded Power Cords...

"With our New Gen 6 release, the ground wire is disconnected from the female IEC. Improvements have been made for exceptional tonal balance."

Hard to believe that Audio Envy, or any company for that matter, would produce/sell something like this. Totally irresponsible, IMHO.

"It was the Audio Envy site that led to this question..."

No reflection on you whatsoever. Hopefully, the discussion of safety-related issues with ungrounded power cables has been informative.
