Sherod I have VSF for the mids and a set of CAST for the tweeters only. It is not that I am unhappy with the VSF in the midrange. It is likely as simple as the VSF's revealing the weak source. I suspect it is the slower vintage cap going through oil smoothing out the digital stair step sound. I am running 24/7 for break in. (don't want to pile the hours on cartridge)
Part of the reason for this is I did lots of reading on caps (tweaks) and guys would say they liked or did not like but I never knew what kind of improvement it meant for the buck.
The tweeter (Duelund) caps made at least 10x the difference from an old NAD Cd player to a Linn Karik or at least 10x the difference that I heard from a 1k pre amp to a $3k+ pre amp. In the store I have heard 3k CD player to the 6 or 7k CD player and the Duelund in just the tweeter caps is 10x that. So I am not unhappy with Duelund in the midrange as the vintage blew away the Mundorf's I tried. So the vintage was not weak in the first place as a 28 year old cap still sounded MUCH better than brand new (200 hours on) Mundorf Supreme.
I have personally e-mailed and thanked Duelund for making these fantastic foil caps.
