QED Reference Audio 40

An impressive stereo interconnect that ushers through a high-quality sound

The Reference Audio 40 looks like a serious stereo interconnect. Build quality and feel are very reassuring – you’re immediately drawn to the smart-looking ‘Analoc’ locking plugs.

QED claims these give a higher-quality connection with your kit.

Performance

Well, the Reference Audio 40 certainly ushers through high-quality sound.

You are made aware of a much broader and more expansive soundstage compared with Ecosse’s Baton Mk2.

Play Drake’s Hold On We’re Going Home and the QED interconnect brings fantastic depth and dimension.

Bass notes appear to plunge deeper and there’s a meaty, mature tone to music, but not at the expense of control or agility.
