I actually can’t compare it to the v6 op-amps that came with the Conductor, since I swapped them straight after I verified that the newly received product worked correctly. That said, I really love the sound coming out of the Conductor 3XR with the v7 vivid op-amps, powered using the Super Charger (3A).
The op-amps were relatively easy to swap, just the zip ties were a bit of a hassle. Fortunately, I had a few compatible zip ties left at home. Burson could perhaps supply spare ties of the right size with the new op-amps, at least when bought as a Burson product op-amp upgrade. :)
