I didn't care for the HE1K ver1 when I heard it but I've yet to hear the ver2 so I don't know if there was enough of a change to sway my ears but I did like the HE560 over the HE1k ver1 since the HE1k was too mellow sounding to me and made some jazz and rock tracks boring but if you listen to mainly well recorded/mastered classical and opera the HE1k is a better choice over the HE560. For me the HD800 and SR009 (traded to a good friend) are the best for classical IMO. The HEX is a great sounding headphone if you want to use it with a DAP or low power phone but for me it was a bit too smooth and a bit boring at times and its why I went with the EL-8 open since its a more exciting/dynamic sound to me but the HEX is the more comfortable of the two.While you are here DavidA, i still haven't purchased the he560. I think i need something close to the hek v2 to be fully satisfied. But it's so ridiculously expensive. How close is the he-560? There is also the lcd2 classic, but it is probably far from neutral. And the Edition X?
Your choice would depend on what you are looking for, if you want a more neutral/reference sound then the HE1K would probably be the better choice over the HE560, LCD-2C and HEX. The main issue I have with most LCD series is the weight, if its not a problem for you then they might be a good option for you. I also have a LCD-2f and while I like it a lot the weight is just too much for me to enjoy them of any length of time.
