With its most recent product portfolio, the CX series, Cambridge is maintaining the quality of its reputation. The new range shifts hues from garish golds and reds to more earth-toned whites, greys, and blacks in order to fit any consumer’s tastes. Each unit’s front tapers out for an appearance that makes them appear to be floating on your shelf.

A volume control knob and individual buttons for stations and sources are included on the front panel’s clean, modern design. A/B Speaker switching enables you to alternate between the speakers on each side of your table without disconnecting or turning them off. A headphone jack is also included in case someone wants to be alone while others are playing video games in public or watching late-night television at home.

Sound Quality

Sound Quality

The audio is clean and sharp without in any way overpowering the musical tone. These speakers are able to portray both low-frequency sounds as well as higher ones without sounding too much like it’s all just “pounding” at your ears occasionally (which I’ve found tends to happen on other systems), so you can feel every beat of your favourite song without getting tired of listening when you turn up the volume or switch to one with more bass.

    I got this great amplifier which I'll never regret

    By Siddharth bora 

    Length of Use: 3–6 months

    Overall Experience:

    I chose the CXA81 after completing extensive research on integrated amplifiers. Stunning! According to the technical assessments, this amplifier will take some time to break in. If that is the case, I am in for a genuinely unique experience. Even though I was switching from an antiquated home theatre amplifier to a two-channel amp exclusively for music, I did not anticipate such a big difference.
