ASUS STX II sound card

[GODInTheWax]

So I've had the Asus STX II sound card for a while now. I've swapped the 3 op amps for Burson V5 op amps, and the card sounds amazing. There is an optional upgrade you can do where you solder on a few MKP devices and I was wonder is it worth doing? I do know how to solder, but I've had some mishaps in the past and this card is very hard to come by now I believe, so replacing it would be a bear. See the link below for what I'm talking about. Does anyone have this card and has done this upgrade? I know this question is a long shot, but I figured I'd ask anyway. Thanks in advance for replies.
