LATEST ADDITIONS

Cambridge Audio has always made fine-sounding a/v receivers but in past years the British brand has had trouble keeping up with the latest features, as often happens with smaller manufacturers competing in the feature-frenetic a/v receiver space. But Cambridge is catching up with 3D and other must-haves with three new models. The Azur 751R has 200 watts times seven, Anchor Bay video processing, an extra sub-out for zone two, and Audyssey 2EQ auto setup and room correction (note that it does not equalize the sub channel). The Azur 651R is similarly equipped with 175 watts times seven ($2200). The Azur 551R ($1200) has 110 watts times seven, Faroudja video processing, and proprietary CAMCAS auto setup but no room correction. Note that these power ratings are into six ohms, so the more customary eight-ohm ratings would be a bit lower (for instance, 120 times seven in the top model). Still, the six-ohm ratings suggest how the receivers will perform with slightly more demanding speakers. And these receivers are far from underbuilt. All have heavy damped metal chassis with large toroidal power transformers and an X-tract heat control system involving a large central heat sink and cooling fans, allowing high performance in a not-too-tall form factor.
