Yes, I'd guess something is wrong.
One thing I forgot to mention is that at the time my friend was using a Sumiko Blue Point Special and now has an Audio-Technica 120E cartridge. Both are good matches with the rega arm. The AT120E is a suprisingly good match, very clean and musical sounding, although not as "warm" as the blu point.
Another killer match with the Plannar 3 (I used to own a P3) is the Goldring Eroica (hi or lo output both work great).
I'm not a salesman, these are my actual opinions.
