I've been told that the Schroeder Reference, w/ the Jan Allaerts cartridge is a Monster. So much so that, it will make the hair on the back of your neck stand on end! at least this was a strong suggestion from a very reliable, and well known audio reviewer (name withheld, something to do with the witness relocation program) when I asked the same question re: updating my Verdier La Platine. I just never took the plunge... the $ was a big concern. At least look into it.
