My new U4 Quad Hybrid can receive ACM and 16APSK. Also can get ACM with my TBS6983 tuner card.
Since the Amiko A3 combo has the same chipset as the U4 Quad (Hi3796M and Hi3136 demodulator), I would expect that it would also receive ACM. But I am not sure about the status of its release in the US (if ever).
