Undertow & Volleyguy,
I asked Duelund for comments regarding your last posts on the technical differences between the CAST and VSF caps, this is the reply I got (my translation):
"While it is true, there is a marked difference between the CAST and the VSF (to our ears at least...) this has nothing to do with differences regarding VDC performance ie. the CAST is not inherently better at handling high DC or AC currents. To achieve that you need to look at either our VSF DC or CAST 630v variants as they employ more layers of paper between the foils.
The remark about the "casing" of the VSF being somewhat of an afterthought is off the mark. The cap being a waxdesign is after several days of vacuum impregnation capable of "holding" its own shape which we augment by using a special lacquer. The upshot of this is ofcourse that there is no resonating box around the cap a highly desirable trait in our opinion.
The CAST being an oil cap at heart is not able to hold its own shape as the raw cap is soft. We take advantage of this by squeezing it in the CAST proces meaning it gets as flat as we can make it. The CASTing layer then keeps it that way. But again this has nothing to do with the standard CAST being better at handling higher currents than the VSF. The design brief was primarily to create a cap that is even less prone to resonance than the VSF."
Me again:
Volleyguy,
When you get the CASTs be prepared for a very long break in period. I used them non stop for 14 days before I was anywhere close to the performance, I'm getting now. To my ears well above the performance of the VSFs.
