Just received my new LPS-1 power supply unit in the mail, hooked it up to my Nuforce Icon-2 and have been amazed with the difference in sound quality! In sheer scale of the the sound, it is like night and day. Where it used to sound somewhat small, thin and veiled, the sound is now much thicker and robust. The sound of the instruments is now much more effortless and "real", like there is more body to the sound. I mean I knew it would make a difference, but I'm just surprised at how much has changed...truly sounds like a new amp!
To all of you out there with Nuforce Icon amps or Nuforce HDP, you should definitely check out the power supply unit - really opens them up to a new level of sound. I'm so pumped!
