aerius

Mine is now. Significant improvement, well worth it, though I do not have a balanced source yet to complete the chain. So far the only headphones I've heard balanced are my Senn 580, a friend's 650, and my own K340. Of those the 650 & K340 improve the most while the 580 only has modest gains, which could probably be equaled by upgrading to a better single-ended amp.

What my parents did when I was a crawler was to sandwich the wallunit and some tables when I was up and about, and then pull them out into the proper listening position once I was safely asleep. In the "safe" position they were still fine for background music so my parents could still enjoy some tunes during the day, but they definitely sounded a lot better when slid out into the room.
