Yep those Fritz may well be the best (I heard them at CAF, absolute top notch) if they would fit I’d go for those if budget allows. Most any amp should produce beautiful music with those. An 8 watt tube headphone amp was used at CAF and the results were simply stunning! Note they are rear ported, if that matters.
If you check the fritz speaker site you will find other models that do fit in a $2000 budget that might also be worth some consideration.
