What amplifier does the Wharfedale D320 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 281 amplifiers against it.

Your system

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.

per channel, into 8 ohms

To hit 95 dB peaks at 3 m from a pair of Wharfedale D320, you need at least 15 W a channel. More than 100 W is wasted here — that is all Wharfedale rates the speaker to take.

  • 95 dB target at the seat
  • +4.8 dB for 3.0 m of distance
  • -3 dB for a stereo pair
  • -85.0 dB effective sensitivity
  • 2 dB allowed for optimistic published sensitivity
  • Published sensitivity 87 dB, used as 85.0 dB per watt.

OSD Nero Stream ARC with the Wharfedale D320

Excellent match
5 dB of headroom - enough, but at the modest end for this speaker, which takes up to 100 W.
Rated down to 4 ohms, comfortable with an 8 ohm speaker that dips to 3.8.
Power nearly doubles into 4 ohms (50 W to 100 W) - a stiff supply that copes with hard loads.

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.

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 Wharfedale D320 specs.
