have you thought about making your chords richer??

You can do so by adding the 2nd (or 9th if it's one octave higher)
-0---0-----0-----0------------
-0---3-----0-----3-----------
-2---2-----0-----0------------
-2---0-----4-----2-------------
-0---------2-----3------------
-----------0-----------------
A9 D9 Em9 C9

There's also the 4th (or 13th same reason)

-0---3----0-------1--------------------------
-3---3----0-------1--------------------------
-2---2----2-------0------------------------
-2---0----2-------2--------------------------
-0--------2-------3-------------------------
----------0---------------------------------
A D E C

Try other ones two, but those are the most effective ones. (There's the 7th too, but I guess you know those)
