I have been thoroughly enjoying my A07, never would of thought Id actually of kept it after giving class D a run again after disliking offerings few years back in my price range. I came across the A3001 by Aiyima which looks like can be used as either a Sub amp or a full frequency amplifier with one channel. Anyone using one in a dual mono setup? Also seeing how the A07 has 3.5mm aux output, could I run it into one of the A3001 and power one speaker off the A07 and other off the A3001, not my first choice but just tossing ideas around. Thanks in advance.
