Question Onkyo Dx-7211 mod questions

Dear All,

I got a Dx-7211 from my friend, but no matter how I change caps or opamp, the bass just cant get any deeper (or even punchy)... I have removed the muting transistors, the output caps and changed opamps.. the mod gives better high end and resolution but not bass... I wonder if the signal path can be further modified (especially those filters), I dont have enough knowledge to understand those filters around opamps, or it is the characteristic of this DAC chip? I am so confused! would somebody please help me out? thx!
