Just a suggestion...
I have a APL 3910.
Perhaps your modded 3910 requires a different interconnect and power cord .
Try a silver interconnect like AZ, Kimber Select,Ridgestreet Audio, Purist Dominus, etc.
It may tighten the bass and open the sound.
The Purist Dominus power cord is awesome with my APL 3910.
