No, but I think I will go ahead and make one.
I was sort of holding off just because you can pretty much some up all the differences in a paragraph. But for those people who want the more in-depth nitty gritty stuff I can post those my lengthier descriptions to accommodate them.
Also, do you (or anyone esle) think it's redundant to post a thread for a review and then also post it in the "reviews" section of a product? I noticed that Head-fi lets you post "Reviews" know and the review then gets tagged to the product and also shows up under your profile as a review.
Would it be redundant to post a review in both places (a thread and the tagged review)? I like actual threads because it's much easier to discuss things, but it's also seems nice to have the review that easier to find and is linked from the actual product and the user and what-not...
I imagine that part of the reason the K712 could be considered "less picky" about amps is simply because it's a bit warmer and fuller out-of-the-box. People traditionally complain that the Q701 can sound too thin/bass-light/bright off some (probably neutral) amps and that you needed to search for an amp that would make them sound warmer/bassier/whatever. With the K712 though, it's easier to make them reach that "potential" due to them already sounding that way out of the box.
