Amplification
Watts are easy, current is not.
Integrated, pre and power, or a headphone amplifier. This is where system matching stops being theory and starts being the difference between good and unlistenable.
Do you need it? Only if what you have cannot drive what you own. Amplifiers age extraordinarily well. Keeping yours is often right.
Two numbers off the back of your speakers decide most of this: sensitivity in dB, and nominal impedance in ohms. Our calculator turns them into a watt figure, and it will often tell you that what you own is enough. Then look at your room. A large room with insensitive speakers is a current problem, not a watts problem, and the two are not the same.
An amplifier is only ever right or wrong for a particular speaker. We do not sell loudspeakers, which means we can be plain about them: what is written on the back of a speaker decides what this pillar has to be, and the part that matters most is usually not written there at all.
In plain language: Sensitivity, The 2.83 V trap, Impedance, Headroom, Watts
