Ortofon SPU Royal GM

This cartridge is quite heavy at 30 grams, so you need a tonearm capable of balancing that mass. It is designed specifically for tonearms with an SME-type headshell mount, which is standard for the classic SPU form factor.

The Replicant 100 is a highly refined profile that tracks the groove with much greater precision. You will notice significantly more detail in the high frequencies and a cleaner, more accurate reproduction of complex musical passages.

Yes, because it has a low output voltage of 0.2 mV, you will need a high-quality moving coil (MC) phono stage with sufficient gain. Ensure your phono preamp can handle a load impedance of greater than 100 ohms to get the best performance.

Electrum, an alloy of gold and silver, is used for the coils to ensure the signal transmission remains as pure and uncolored as possible. This material choice helps maintain the warmth of the SPU sound while adding modern clarity and transparency.

Not at all. While 3.0 grams is heavier than many modern audiophile cartridges, it is the correct tracking force for the SPU design. When set up properly, it is perfectly safe for your vinyl and helps the stylus maintain stable contact with the groove.
