HanssoN,
This doesn't come as so much of a surprise actually. I recently started a thread to try to find out the quality of various headphone jacks on premps, integrateds, receivers, etc., and found that there are many good headphone jacks out there.
In an older thread on the same topic, somebody reported a NAD preamp being easily better than an MG Head.
My sense is that you can get a good headphone jack on some components from B&K, Rotel, NAD, Bryston, Denon, and who knows what else. The jacks on these components compare well with good to excellent headamps. I now have no plans on ever buying another dedicated headamp, as a preamp offers so many more features than a typical headamp. The only problem to me seems to be getting good information about the quality of headphone jacks on components that rivals the quality of the headamp reviews on this site.
