Onkyo AV receiver maintains audio fidelity at all times

Power has its price

There are six digital audio inputs, divided equally between optical and coaxial, and you’ll find dual subwoofer RCA jacks too, in case you want twin-sub action in your home cinema.

The remote control is pretty awesome too. It’s larger than the ones that come with Onkyo’s cheaper systems, but feels comfortable in your hand.

Its controls are generally within easy rich of your controlling digit.

If you’re wondering why the TX-NR5007 is over four times as expensive as Onkyo’s excellent TX-SR608, the answer is simply that it’s hugely powerful.

The TX-NR5007 is THX-Ultra2-Plus-certified, which means it’s aimed at rooms of up to 914 cubic metres, with a viewing distance of more than 3.66m between the screen and your eyeballs.

Put simply: the NR5007 is aimed at people who have huge rooms and video projectors.

Does this mean you can’t use the TX-NR5007 in a small room? Certainly not.

But you probably won’t be able to get the amp up to the reference level of the THX Ultra2 Plus certification.

The reference level is designed to produce the same fidelity and volume of sound as the director hears while a movie is being edited.

Ramping up the AV receiver to the reference level in a small room would probably prove unbearably loud.

Don’t want to go deaf?

It’s hard to make equipment that works like this, and building amps of sufficient quality is quite an expensive process.

But, whatever the reasons for its cost, the TX-NR5007 is undoubtedly very expensive, and not everyone will want to spend this kind of money.

The Onkyo TX-NR5007 is expensive and too powerful for most households’ requirements, but if you can afford it, you’ll feel as well disposed towards it as we do.
