Rauliruegas, thank you for your comments. My contention is that many unipivot tonearms show evidence of instability in the azimuth plane, when cartridges which feed large amounts of energy into the tonearm are used. This is less problematic when medium compliance cartridges(which feed lower amounts of energy into the arm) are used. This is why I recommend what I do. I agree that this is a tonearm design related issue, and many unipivot tonearm makers are showing a trend towards stabilizing features on their arms. I'd say that this is directly related to this issue. All tonearm types have their deficiencies, and this is one that happens to many unipivots, with certain cartridge types.
However, I do accept that many people find these matchups to be listenable in their systems. When making recommendations, I try to show people things to consider when they make their choices. I am in no way trying to tell them what they must do. They can do as they please. But it would be remiss to ignore the things that commonly happen with these combinations. So, I make my recommendations from my experience, and the experience of others that I know, and hope to help them in their quest for better sound. In my experience, tonearm stability considerations(in all planes) are as important for the cartridge matching as the mass/resonance is, when high-energy low compliance cartridges enter the equation.
Not everyone would agree with me, but that is my opinion.
