When looking to purchase a high-fidelity amplifier, there are several factors to consider. Here is a buyer guide to help you make an informed decision:

Power Output: The power output of an amplifier is measured in watts. Consider the power requirements of your speakers and choose an amplifier that can deliver enough power to drive them effectively. Higher power output typically results in better sound quality and louder volume levels.

To determine how much power you need, you need to consider the sensitivity of your speakers, the distance between your listening position and your speakers, plus how loud you want to listen.

For example, imagine if you usually listen to jazz music at relatively low volumes (around 90dB) in an average-sized room. Then you sit about 10 feet from the speakers, which have a sensitivity rating of 87dB @ 1w/1m. In that scenario, you’ll need an amp pushing between 30-50W, allowing some headroom for peaks in the music. As you can see, a relatively modest amp will work in this case. For specific calculations, you can consult your sales engineer.
