There is always a level up, in audio. No one debates that. I'm quite certain that a Bolder or Esoteric source would sound better than my DAC. But I don't think that it's the case that a $2K source and $3K amp are not appropriate equipment to review a $2K headphone with. I think they are.
I want to re-iterate that I very strongly encourage people to post their own opinions of the LCD-3 no matter how different they may be from mine. I had very different opinions from some people about the Edition 10, for example - I thought it sounded quite bad, whereas others liked it a lot. I think it's helpful for there to be a wide variety of opinions.
I also prefer for people to be respectful of each other, and I would humbly ask that this thread stay respectful.
