Sumiko Blackbird is a popular high-performance moving coil (MC) phono cartridge that is available in both high and low output versions. The two versions differ in terms of their output voltage and impedance, which can affect the sound quality and compatibility with different phono preamps.
Output Voltage
The main difference between the Sumiko Blackbird High and Low Output cartridges is their output voltage. The high output cartridge has an output voltage of 0.5 mV, while the low output cartridge has an output voltage of 0.2 mV. This means that the high output cartridge will produce a stronger signal, which can be helpful if you have a phono preamp with a low gain setting.
Impedance
The two cartridges also have different impedances. The high output cartridge has an impedance of 135 ohms, while the low output cartridge has an impedance of 25 ohms. This means that the low output cartridge will be more compatible with phono preamps that are designed for low impedance MC cartridges.
Sound Quality
In terms of sound quality, the Sumiko Blackbird High and Low Output cartridges are very similar. Both cartridges are known for their excellent clarity, detail, and bass response. However, some listeners have reported that the high output cartridge has a slightly warmer and more forgiving sound, while the low output cartridge has a slightly more analytical and revealing sound.
Compatibility
The Sumiko Blackbird High Output cartridge is compatible with a wider range of phono preamps than the low output cartridge. This is because the high output cartridge has a higher output voltage and a lower impedance. However, if you have a phono preamp that is specifically designed for low impedance MC cartridges, then the low output cartridge will be the better choice.
Overall
If you are looking for a high-performance MC phono cartridge with excellent sound quality and compatibility with a wide range of phono preamps, then the Sumiko Blackbird High Output cartridge is a great option. However, if you have a phono preamp that is specifically designed for low impedance MC cartridges, then the low output cartridge may be the better choice.
Which one should you choose?
The best way to decide which Sumiko Blackbird cartridge to choose is to consider your system and your own listening preferences. If you have a phono preamp with a low gain setting, then the high output cartridge may be the better choice. If you have a phono preamp that is specifically designed for low impedance MC cartridges, then the low output cartridge may be the better choice.
If you are unsure which cartridge to choose, it is always a good idea to consult with a qualified audio dealer. They can help you to assess your system and choose the cartridge that is right for you.
