A receiver is basically the brains behind your entire AV setup. If you’re looking to smarten up your system, Woot has a great deal today.

Right now, the website has the Pioneer VSX-521-K 5.1-channel receiver listed for just $134.99. This is a great deal on any receiver, let alone this one. Just know that you’re going to need to kick in $5 extra to ship the thing. 

It’s a decent receiver for 5.1 setups, though, offering 3D support via four HDMI v1.4a inputs. Promising 110 watts of power for each of its five channels, the VSX-521-K also has Dolby TrueHD and DTS HD decoding, Audio Channel Return, and the Multi-Channel Acoustic Calibration system (MCACC).

It’s also compatible with Bluetooth devices, if you want to add in the Pioneer AS-BT200 Bluetooth adapter.

Like all Woot deals, this one is only good for the day. That means you’d better snag one quick!
