Dedicated power amps take an AVR (Audio Visual Receiver) to the next level. There are three good reasons why you might want to consider upgrading to dedicated power amps. The first is to upgrade your AVR’s main, stereo channel. This not only gives a huge boost to 2-channel music, but it also takes the strain off the AVR, letting it ‘focus’ on the surround channels. The second is to gain an improvement in sound quality and power all round. Finally, they let you add additional channels, making it possible to take advantage of exciting new formats from Dolby, DTS and IMAX.
Provided your existing AVR has multi-channel RCA phono or XLR outputs, upgrading to dedicated power amplifiers is very straightforward. In most cases, you’ve got two options. Either upgrade the main, stereo channels, giving you superior stereo sound and making life easier for your AVR’s ability to drive the other channels. Better still, upgrade all the channels using a multi-channel amp or a stack of power amps. Simply connect via phono or XLR leads, set the levels and you’re good to go with an instant upgrade. Unlike AVRs, dedicated power amps have just one job to do – amplify the input signal – making them supremely fit for purpose.
Most power amps provide you with a boost in power but, more than that, higher quality componentry enhances the sound quality as well. With dedicated power amps the sound becomes more dynamic, impactful and yet clearer, too.
Many AVRs feature additional, line-level output channels. What is normally a 7.1 or 5.1.2 channel AVR, for example, may have line-level outputs for 9.1 or 7.1.2 channels. This means that simply by adding a dedicated power amplifier, or two, you get easy access to those extra channels of sound. Extra channels equal extra immersion and are especially noticeable when upgrading to Dolby Atmos / DTS:X.
