We knew this Sony was special, but it's taken the extra-close comparison of a Group Test to see just how special it is.
To cut a long story short, the STR-DA5400ES is so good, it's forced us to modify the ratings of every receiver around the same price.
There's nothing particularly special about the way it looks, though, with the exposed knobs and buttons doing nothing to entice the eye. But it's the specs that first hint at greatness.
Specification shines brightFor a start, this 7.1 receiver has no fewer than six HDMI inputs and two outputs. Most people would use these for a TV and projector, but should you use the second output for a TV in another room, you'll be pleased to hear it has its own Faroudja video processor that upscales to 1080i, as well as a dedicated remote and GUI.
More after the break
Of course, the first output has its own Faroudja processor (which upscales to 1080p), remote and GUI, and operating the device is a joy, thanks to Sony's XrossMediaBar.
The '5400ES also has perhaps the quickest and most efficient mic-driven set-up we've seen, producing close-to-perfect results in a matter of seconds.
This means you'll be able to sit back and enjoy your new receiver in a flash – and what a thrilling performer it is.
