Modify Soundcard Help Needed !

Hi there,

some time ago i bought a Audiotrak HD2 as replacement for my Terratec DMX6fire card.

Good thing is it comes with OPAs on sockets.Have tried several
types and currently i am stuck on BB OPA2111 as i like em best
but will try other types.

As a next step i have changed al capacitors located on the card to
Rubycon ZA/ZT and Elna types.This was another good improvement of the sound.

My next question would be is there anything else that could be
modified clock other parts etc. ??????

heres a good picture of the original card :


Best regards
