I too disagree with your impressions. I assume your cartridge is either not broken in yet, or you have not adjusted the gain and/or loading to get the most out of this cartridge.
Can you tell us what your phono stage is, along with the gain and loading settings that you are using?
The XV-1S is the absolute best cartridge I have ever heard, both in my system, (past cartridges include Koetsu Rosewood Signature, Shelter 90X), and in my friend's system, (his past and present cartridges include Koetsu Rosewood Signature Platinum, ZYX Universe, and an EMT, although admittedly, the last two are probably the XV-1S's equal, just with different strengths).
My two cents worth.
