I have found the mint Best Tractor easy to use and an essential tool when setting aligning my XV-1S on my Vector Model-3 tonearm.

With the Vector-3, I keep the VTF between 1.88 - 1.95grams max! I don't go above 1.95 simply because I don't want to put additional stress on the cantilever & cartridge suspension. My particular XV-1S has 2,000+ hours of play on it. The bass dynamics are awesome and the vocals are simply amazing. I spend most of my time doing critical vinyl to DSD transfers and I will re-record any album side that has any hint of sibilance in the vocals or lacks dynamic impact. I use Mo-Fi LP#9 stylus cleaner after every single album side. I also own two Onzow Zerodust cartridge cleaners but never use them. LP#9 high purity alcohol is all that I use and my Dynavector keeps on trudging along. I'm still amazed that the cartridge sounds this good after so many hours of play. I'm sticking with the low VTF settings and the mandatory cleaning after every album side.
