@hilde45 Did you ever complete your QS cap upgrades? Reading this thread its not clear which QS model you are working with. If you have a newer QS item I do believe the capacitors if white in color are already Film and Foils if you replace these with any kind or metalized polypropylene cap you're most likely doing a down grade. In almost all cases a film and foil cap will be sonicly superior to a MP regardless. Mike at QS now has available on the QS website Film & Foil capacitors to replace common QS sizes .27uf, 2.0uf, and .056uf I believe. If yours are yellow in color or not identical to the new QS caps you should consider the QS labled film and foils. Im currently updated an older QS full function preamp that seems to be using older QS Metalized Polypropylene caps. I will be using the newer white film and foils from QS. You can view my progress on lowpower audio on youtube.
Tube Amp, Preamp upgrades -- what did you do that improved your units?
Hi folks,
If you upgraded a point-to-point wired tube amp or preamp, what did you upgrade?
I assume capacitors, but was there anything else which you upgraded that made a genuine difference for the sound?
I am looking into improving the caps in my Quicksilver stuff, but before doing that, I am curious if there's anything in addition to caps which I should consider.
Thanks.
