AV receivers serve one purpose – to connect all the multimedia devices you own in one place. The Yamaha RX-V671 is a physical hub for all your entertainment needs. It connects your Blu-ray player to your HDTV and surround-sound speakers. Nearly any device you own, whether you bought it in 1980 or yesterday, is compatible with this AV receiver, thus earning it our TopTenREVIEWS Silver Award.
This versatility of the Yamaha RX-V671 is wholly dependent on its wide connectivity array. Yamaha did a great job of including the newest digital connection ports such as HDMI as well as the established analog connections such as coaxial, component and composite.
Furthermore, this AV receiver produces nearly unmatched sound and picture quality. Compound all that on top of its GUI and online capability to stream content from services such as Pandora and Rhapsody, and you have a product that truly connects every entertainment outlet you own.
AV receivers by their very nature aren't beautiful machines. They're utilitarian and boxy. That being said, Yamaha did a good job in making what is essentially enormous router into a sleek-looking machine that meshes well with any home entertainment center you choose to apply it to.
When we measured the performance of the AV receivers on our side-by-side comparison chart, we looked at a few key features. The Yamaha RX-V671 excelled in all the technical specifications we looked at. For example, the total harmonic distortion with this AV receiver measures a mere 0.09 percent. That number may as well be zero because the human ear cannot detect harmonic distortion that low.
Likewise, the frequency response of the Yamaha RX-V671 ranges from 10Hz to 100kHz. This response spans the sound spectrum that the human ear can hear. Therefore, every sound, note and voice on any media you route through this AV receiver comes out as crisp and clear as the day the creator recorded it.
Another performance statistic worth mentioning is the Yamaha RX-V671's power consumption and output. Each the unit's 7.1 channels of sound put out 90 watts of energy. The total energy consumption of this AV receiver is 460 watts. The former number is lower than many competing AV receivers; the latter is the heaviest consumption of any device on our side-by-side comparison chart. They're both healthy numbers, yet they cancel each other out when you consider how much power the whole unit draws and puts out.
The connectivity array on the Yamaha RX-V671 includes every port and connection we looked for when we rated and ranked AV receivers. In most cases, the unit included more than one port for each type of connection.
The mix of new digital technology with the familiar analog connections means that you have the ability to connect anything from that CRT TV you bought in 1985 to the HDTV you bought at the store last week. Both of these devices, and many, many others, are fully compatible with this AV receiver.
On the rear panel of the Yamaha RX-V671, you'll find five HDMI input ports and one HDMI output port. Just these six ports allow you to connect every HD device you have to this AV receiver.
