Raul, according to the vdH website, the recommended load for the .35mV Condor is 500 ohms, not 200 ohms, and 500 ohms is within the suggested range. In any case, the "optimal" value will not be exactly the same in each system because of the difference in tonearm cable impedance and the effective impedance of the circuitry of the phono preamp (or the impedance of the step-up transformer if you are using one.)
That is why it's important to have a mathematical method to determine a working range (a high load limit and a low load limit for each cartridge) and then to have a reliable way to hear when the load is a little too high or a little too low, or just right.
