What DAC are you using and any other sources? I just had a customer go through this with a pair of A3s in roughly the same price range. The A series from Magico is not that forward. If you have a warm source, you could end up too warm and the system could drift dark with some of the amp choices above.
With a more forward DAC, take a look at AVM. The A5.3 is a lovely integrated amp for the money and has plenty of power to drive the A1s. AVM and Magico were paired together at the NY Audio Show in 2018 and got tremendous feedback. I have a demo of this amp at the moment and listen to it virtually every day driving Vivids with a Chord DAC and it is really musical. Alternatively, the same combo with an Aqua DAC or a Rockna Wavelight would border on dark.
