Replaced OPA2134 and OPA2604 chips in my Music Hall DAC 25.3. Since it comes with standard 8 pin DIP sockets, installation took only minutes carefully observing orientation. The V5s definitely elevate the performance in many subtle ways. You hear more inner detail without any false brightness. There’s better focus with voice and instruments. You’re better able to follow rhythms in the background. Very nice results for a modest cost.
