Connectivity Options: Consider the connectivity options available on the amplifier. Look for inputs such as RCA, XLR, or digital inputs like USB or HDMI, depending on your audio source. Additionally, check for outputs that allow you to connect to multiple speakers or subwoofers if needed.
When shopping for an Integrated amp, you need to ensure it has all the inputs and outputs required to connect your gear. All Integrated Amplifiers have several (usually 4-6) analog RCA line inputs for a CD Player, a DAC, or Tape Deck.
Some amps like the Cambridge Audio CXA81 have balanced XLR inputs. XLR cables produce less noise over longer runs. If you have a component (like a DAC) with a balanced XLR output, you may want an amp with this option.
Suppose the amp has a built-in DAC (Digital to Analog Converter). In that case, it will have Coaxial and Optical Digital Inputs for digital sources like a music streamer or CD Transport. Some have a USB input to play music from a computer. Others have HDMI inputs to pull digital audio from a TV.
In addition, many amps have a dedicated phono input which is essential if you plan to use a turntable (that doesn’t have a phono pre-amp built-in). A subwoofer output is also nice if you want to add some low-end (via a powered sub) to your system.
