I'm using a Musical Fidelity X-Cans II on mine and it sounds great, just make sure that you upgrade the tubes.I used to only used them on my SF Line 2SE but a seperate amp really does make a difference.
But if you really want a great headphone amp check out the top of the line from Headroom.
Hi Mcne, on the X-cans II, just replaced the two tubes inside to your choice of 6dj8,6922 or 7308 NOS tubes of your choice.I prefered Amperex 7308 on mine.If you have questions on how to actually open it and replaced the tubes just email me.
