PLCC Extraction Tool

Square IC PLCC Extraction Tool, $9.99, Radio Shack
  Have started opamp rolling in the iBasso D4, need to use an PLCC Extraction Tool to remove the opamps.

D4 Topkit

iBasso D4 Topkit, $60 purchased from HiFlight on Headfi.org
  Purchased D4 Topkit with optional L/R opamps.  Sound Quality has a larger soundstage, seems more powerful than before and "natural sounding", like the sound opened up and more musical.  Still need to try the optional L/R opamp.
