Take a look at the follow site for information on headphones. They like the Grado SR-60s and also suggest that these Grado's are about as far as you can take it, without using a headphone amp.
Also, look at the following Audiogon review on the SONY MDR-7506. The reviewer also offers some additional headphone options, if the SONYs don't do it for you.
And finally, take a look at this review for a Creek Headphone Amp, in which the reviewer offers praise for the headphone jack on his Rotel amplifier.
I own the Grado 60s. They are fine sounding headphones. My only gripe is that they can get uncomfortable (tight feeling) after awhile.
Regards, Rich
