I have never heard the Dynavector 17D3 but I have owned the Te Kaitora Rua and XV-1s and I am using it with a ZYX CCP-1 (not a transformer). I had good results with the Dynavector PHA-200 as well. The Ortofon T20 is another good one (cheap). I hade a real mismatch with the Lundahl-transformer (1681) wiht the Dynavectors.
If you go with a transformer, make sure it will match your cartridge, because you could go really wrong here.
