See those expensive paper in oil caps? Those things cost me nearly $25-$30 bucks EACH back in the 1990’s. I bought several different versions and tried using them in various guitar amplifiers, guitar effects, and guitar wiring projects. They ultimately wound up being better suited here in a diorama made by Mrs. Arthur. One of the main reasons is that they exhibit too much DC leakage, among several other things. Swamping the bias of successive downstream gain stage grids with DC offset isn’t suitable for HIGH performance audio projects which meet the standards I’ve set for myself. I’ll gladly discuss this with other designers Ad Nauseum…
In the beginning, I was roped into overly hyped audio components based on their price tags and just from reading too much BS published by a few self-proclaimed “gurus”. However, there IS some truth where the superior price tags of components offer better audio performance in some cases; but not all. It depends. Paper in oil caps definitely don’t offer higher performance in my experience. When choosing superior parts for builds, I go for overarching characteristics which include offering some unique operation parameters, high reliability, high stability, plus desirable audio characteristics (which can be very subjective). Once these things are in balance with one another in an actual amplifier, then I’ll consider it for further use.
