I've driven my Stages with several amps with good results. The load is not that difficult, as compared to some of the larger Apogee models.
Much depends on your tastes. I had the mentioned Aragoon 4004 MK II in my system for a short time. While it had good base control, the mids and highs lacked refinement and clarity.
I've had a Bel Canto Evo 2, Gen II for the last 8 months and I'm pleased with its speed, clarity and control on the Stages.
It's best if you can try out the amp to get a feel for its sound character, especially if it uses tubes.
