Median

Nominal Impedance of the 4 Ohms means that the Sonus faber Sonetto I is a difficult to drive speaker from nominal Impedance perspective, make sure that you choose an amplifier than can provide 4 Ohms for this speaker.

Many AVRs (audio/video receiver) in the market may have difficulty when the speakers dip below the 4 Ohms levels (this may cause clipping or even physical damage), so we recommend to not pair the Sonus faber Sonetto I with an AVR but use an Integrated Amplifier instead.

Sensitivity

With a sensitivity level of only 87 dB, Sonus faber Sonetto I is a difficult to drive speaker from Sensitivity perspective, make sure to choose an amplifier with a high output if you like listening to your music at high volume levels. You may especially have a hard time using Tube amplifiers which are traditionally very low power compared to Class A/B or Class D amps. Work out how loud the Sonus Sonetto I plays in your room →

Running more than one pair from a single amplifier? Check the load it would present →

What amplifier does the Sonus Sonetto I need?

We check power, impedance safety and current delivery - not just watts.

Prefer to browse? Integrated amplifiers under $1,500, or every amplifier we cover.

Input Type

Sonetto I has Binding post type connectors and lets bi-amping/bi-wiring. Bi-wiring can enhance the overall transparency of your loudspeakers by using separate speaker wires for the low and high-frequency drivers from a single amplifier. Bi-amping, on the other hand, involves using separate amplifiers for the high and low-frequency drivers, potentially resulting in a greater dynamic range and reduced distortion.

  • Speaker Cable and Connectors
    • Speaker Cables with Banana Plugs: If you know the lenght of the cable you need, this is the easier option to connect your speakers with your amp.
    • Speaker Cables without Connectors: If you are not sure about the lenght or need longer than standard cables with plugs, choose this option.
    • Banana Connectors and Plugs: If you chose the cables without connectors option or already have some cable around, pick the banana plugs separately.
  • Vibration Isolators: IsoAcoustics isolators are our favorite isolators but you may find more affordable options too.
  • Acoustic Panels and Treatments: Your room is as important as your stereo equipment so acoustic treatments goes a long way in improving the overall performance.
