help me with a DAC decision please

i'm looking to upgrade my wadia DAC. My first choice would be to have it also act as my pre. My mind could be changed on that however. I am looking seriously at the April Music Eximus. Does any of the Metrum offerings fit in here? I  need some help finding comparative models from other makers. There is no place for me to see any close by. I have to wing it off of the web and your recommendations. I do not object to buying used.My budget would probably be under 3 grand new or used.
thanks for all the help
