and felt pretty smug about for the last 20+ years w/ my very decent passive VC setup, an impedance friendly setup at that, i.e very short cables, high input impedance on the amp 75kOhms, 50kOhm Alps pot and the low low impedance out of a DAC of 30 ohms. I know there was clarity galore yes, but as I turn up the volume, some sorts of compression kicks in and the sound is still clear but congested, I always felt my system is more capable than that. I loved the clarity but there is persistent thinness to the sound. The sound is clear but flat, if you know what I mean. So there was this "what if" nagging at me through several passive potentiometer changes, from cheap Shacks stuffs to TKD to Alps (I started PVC experiment in 1986!) Well, I know now that there is almost as much plus and minus in PVC as in AVC and impedance mismatch can really tip the scale either way. I know now that the precious low level line out that contains both voltage and current that are easily messed up by lousy connections or equipments.
