Neal,
I don't know if you still have you 400xi, but if yes I would suggest a change. I used to own it and I found it analytical, neutral, but not very musical. Instruments lacked body, and the dynamic was poor. It was quite annoying.
I upgraded to a Plinius 9200 which is as transparent and neutral, but will give you back the life you may miss with the 400xi.
Hope this help.
Fabien
