I bought a ZxR and based on the advice in this thread, I also bought Burson V5i op amps.
I am not an audiophile and I had no idea what I was doing when I tried replace the stock op amps.
I bought this IC extractor to do the job:
https://www.amazon.ca/HV-TOOLS-HV85...R94/ref=sr_1_2?ie=UTF8&qid=1516339246&sr=8-2&
However, taking out the stock op amps with that tool was a nightmare. The main problem is that there is very little space between the op amp sockets and the cylindrical parts of the sound card that resemble batteries. I could not fit the tool around the op amps properly. When I finally did manage somehow to yank out the stock op amps, most of the time their pins got bent to Hell because half of them were still stuck in the socket in a horizontal position as the other half of them jerked out in an awkward vertical-diagonal angle. The op amps now look like a spider that has had the lower half of its legs crushed.
Later, when I tried to put the Burson op amps into the empty sockets, that was a second nightmare. Usually when I tried to line up the pins with the pinholes, and then press down, the op amps would not go down. I was terrified that I was going to wreck the pins before the op amps were installed. Somehow, after spending a lot of time with each one, I eventually managed to get them all installed without damaging them. That felt like a miracle.
Now I'm worried that if I ever have to take out my Burson op amps, I am going to wreck the pins in the same way that I did to the stock op amps.
Can anyone give me guidance about how to not wreck the pins when/if I take the op amps out?
Likewise, can anyone give me guidance about to guarantee I won't wreck the pins when I try to put new op amps into the empty sockets?
Are there any types of professionals who can perform those tasks for me for a reasonable fee (like $30 or less)? If so, what is the name of their occupation?
As for the sound: IMO the ZxR sounded like garbage with the stock op amps, but it started to sound amazing after I installed the Burson op amps.
