Thanks for the suggestion. 300€ is already a stretch (my comfort zone is ~250€). The audiolab I have found locally, thus would be saving on shipping costs, plus is a combo unit. I wish I could afford the Crack, especially that one.
This is a great suggestion. Actually leaving Greece would make a lot of sense, not just audio-wise! As far as I know there is no return policy whatsoever, so I will just have to rely on reviews and opinions.
I only heard the "Little Dot MK IV" in your list with the HD700, it wasn't bad for HD700 but I'm not sure about the HD650.
