Thanks to everyone for the replies re: balanced vs single-ended. I've updated my endgame setup plans to Gungnir Multibit > Mjolnir 2 > LCD-3. I'll be keeping the Fostex single-ended for general use around the house, especially in the home theater (they do an awesome job with movies and games). Though the LCD-3 will set me back a bit, I have no doubt that they'll be worth the cost. I'm looking forward to the peace of mind knowing that I have a proper endgame setup without weak links, and enjoying it for decades to come.
