I can't disagree more, because I'm still searching for the "best" cartridge and I tried over 60 of them (new and old, mm/mi and mc). Using 4 different tonearms is better than using one.
It was an illusion that I could use one great cartridge on one great tonearm, this is the reason why my Reed 3p "12 inch is not in use now. This is the reason why my most expensive modern LOMC are not in use now.
In my perspective I only discovered something more interesting, more involving and it wasn't a compromise in sound at all.
As I mentioned in my previous post, with tonearm (with removable headshells) like Ikeda IT-345, FR-64fx, 66fx, 64fx PRO, 64s, Lustre GST-801, Victor UA-7082, Technics EPA-100 mk2 and much cheaper Denon DA-401 ... no one can go wrong if they are in use with properly matched cartridges. I have all those arm and very happy about performance.
