Putting the Burson V6 Vivid Opamps in the buffer section yielded very good results. The process of installing them was pretty simple. Given my strange experience with the I/V stage Opamps, trying to swap out the buffer opamps first seemed like the safe bet. They make discrete opamps that can sound quite nice compared to more traditional Opamps. I decided to try some Opamps from Burson Audio. Given how well this card has served me, I decided to try taking the Opamp upgrade to the next level. I just chalked it up to being something in the design that the JRC 2114D was particularly well suited for and basically gave up on those Opamps. It always sounded like something was missing from the midrange when using anything besides the stock JRC 2114D Opamps. The I/V stage uses dual Opamps, but I had bad results when swapping in my favorite dual Opamps such as the LM4562 or the OP627 (two single OP627 opamps on an adapter board to create a dual opamp). Also, almost all of the Opamps in my "opamp collection" are dual opamps, not single opamps. For that reason I've had little desire to swap them out.
The LME49710 single opamps in the buffer section are basically the single opamp version of the LME49720 / LM4562 dual opamp, which has always been one of my favorites. My attempts at Opamp rolling so far have been limited and/or unsuccessful. The stock Opamps are two JRC 2114D dual Opamps in the I/V stage and two LME49710 single Opamps in the buffer section. For now, I simply used two tiny zip-ties to hold the rear bracket on. If I continue to use it without the cover, I will need to get some small nuts so that the screws have something to screw into. Without the cover, there is nothing for those screws to screw into.
The screws that hold the front of the metal cover on also double as the screws that hold the rear bracket on.

A couple of years ago I swapped from using the X-Fi Titanium HD in my main computer to using a regular X-Fi Titanium (feeding an external DAC via SPDIF). For a long time, I used it in my main computer. It has been a great card for me that entire time. Here I have my trusty old X-Fi Titanium HD.
