The Good Exciting sound quality; well built, smart design; four HDMI inputs.

The Bad No USB media playback; spring-clip terminals for the centre and rear channels; no on-screen user interface; no video upscaler.

The Bottom Line Frugal film fans looking for a fine-sounding, 3D-compatible AV receiver are unlikely to be disappointed by Pioneer's VSX-521. It provides an exciting listening experience, with more polish than you might expect for the price.

If you can live without some of the more advanced frivolity infiltrating the AV receiver market, there are some remarkable bargains to be had. Straightforward multi-channel amplifiers that used to cost around £500 now routinely sell for less than £300. This is great news if you need an upgrade principally for HDMI connectivity or 3D compatibility. Pioneer's 5.1-channel VSX-521 is one such cheapie. It will set you back around £280.

Design and connectivity

At a glance, you'd never think the VSX-521 costs less than £300. It shares the same glossy black aesthetic and build quality as step-up models in the Pioneer line. There's some flex to the chassis but, overall, the finish is of a high standard.

Connectivity is also decent. You get four 3D-friendly HDMI 1.4a inputs -- one more than the even cheaper VSX-421 -- plus two component, four phono AV, two analogue stereo and three digital audio (two optical) inputs.

The Pioneer VSX-521 looks more expensive than it is.

There's also a subwoofer output for the low-frequency effects channel, plus pre-outs for hooking the VSX-521 up to a second amplifier, which is then hooked up to an additional two speakers, if you want to get 7.1-channel surround sound. The VSX-521 supports Dolby Pro Logic IIz too so you can feed sound to seven channels, rather than five.

This may be a five-channel amp, but only the main stereo speakers benefit from decent binding posts. It's disappointing that both the centre and the surround speakers have to use spring-clip terminals.

The VSX-521 lacks any media-streaming talents. Indeed, you won't even find a USB port for local media playback. But you do get a front-mounted 3.5mm mini-jack for your portable music player, and a rear-placed Bluetooth port. If you pay around £50 for Pioneer's AS-BT200 adaptor, you'll be able to stream music wirelessly from a Bluetooth-equipped mobile phone or another compatible device.


The VSX-521 may be a budget option, but it's not devoid of extras. For a start, Pioneer includes the entry-level iteration of its MCACC calibration tool. This is designed to balance and equalise the AV receiver to the acoustics of your listening room. It's simple enough to use -- just plug in the supplied microphone and follow the display prompts.

One feature that's easy to overlook but that's well worthwhile is HDMI standby pass-through. This allows kit to be routed through the VSX-521 via HDMI, without requiring the AV receiver to be powered up all the chuffing time. We suspect this feature will be a godsend for family users.
