What amplifier does the Triangle Borea BR03 need?

Pick a speaker and tell us how loud you listen and how big the room is. We work out the power it actually needs, check which amplifiers can safely drive its impedance, and rank 292 amplifiers against it.

Four questions. Nothing is hidden on price.

Passive speakers only — a powered speaker already has its amplifier inside.
Changes the order only. Nothing is hidden for costing too little or too much.

Were these amplifier recommendations useful?
It helps us tune the matching, and we read every comment.

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 Triangle Borea BR03 specs.
