Power needed
9.5–150 W
per channel, into 4 ohms
To hit 95 dB peaks at 3 m from a pair of Sonus faber Aida, you need at least 9.5 W a channel. Anything from about 19 W to 150 W a channel is comfortable; past that, more watts stop buying you anything.

Good match
10 dB of headroom over what this speaker needs - peaks stay clean.
Has a 4 ohm tap, which is exactly what this 4 ohm speaker wants. Taps: 4 / 8 ohm.
A valve amplifier makes the same power on each tap, so what matters is sensitivity - and at 87.0 dB this speaker is efficient enough that 100 W is comfortable.
Well below the speakers - leaves money on the table, but nothing wrong with it.

Listed separately because they are not a complete system: a power amplifier has no volume control and no inputs to speak of, so you need a preamplifier or a streaming preamp as well. Worth it if you already own one, or if you want to buy the two halves separately.

Sensitivity and impedance figures are the manufacturer's own. We read sensitivity as dB at 2.83 V/1 m and take 2 dB off it, because published figures run high. Treat the result as a well-founded starting point, not a measurement. Full Sonus faber Aida specs.
