I just did my system up last night with Quick Silver and the resolution gains were quite significant. There are a few issues that I hope clear up. These have manifested exactly as described by the Quick Silver creator so I fully expect that I will end up where he claims. At least 36 hours of signal burn-in is recommended before critical evaluation is made. I have 5 hours logged.
I don't have any experience with either SST or Silclear.
