To be honest I did not know that they could vary. But even if they were different I do not think that this could ever make such an obvious difference.

Well, I don't know how many different kinds of HD 650s exist. And I never tried the HD 600 so I cannot comment on this one. But all I know is that some headphone geeks claim that there is an old and a new version of the HD 650 and that the old sounds darker, duller and in some way veiled...

Ok, I haven't been around for a while and now I have just stumbled across this thread but I don't have the time to read all the pages. Therefore I'm asking you to provide me with the HD 700 news in a nutshell. And what is fact and waht is only rumors so far? Thanks a lot!

I am sorry I misread your post. The link I added does not lead to ocean recordings. But I hope you already found some nice ocean sounds ...

Besides 'quiet american' (that really contains a lot of very good binaural recordings) have a look at 'sonic studios' website'. The records by Leonard Lombardo are particularly awesome. And don't miss a file named 'Dogchili' ... ;-)

I'm also a very satisfied Aeropress user. I use it with a Solis burr grinder and with a grind that's a bit finer than for drip coffee but not as fine as espresso and I get great results following the Aeropress instructions ... especially with nice some Guatemala Antigua from my local...

I received my D1 a few days ago and although I think it's a great combo (particularly with the HD650) I'm selling it right again to afford a big DAC. If you're interested please have a look at my offer. - Marco

Ron and jamato, I am still wondering how the sound changes when you leave in the stock buffers and just put in a OPA2111 or a AD8066 ...

The ARC website as well as the program's user interface are only available in German so far. So I am gonna give you the most important facts and try to explain how you will get it work if you want to. Let's start with the facts: You will need: - a Windows PC (I run it on XP and I know...
