        About this report
        This is a report for professionals with a suite of test of headphone amplifier.
        You can see a simple report for "dummies" with explanations of the main characteristics for Creative Sound Blaster X7 LE 4 Ohm Low Gain

        A suite of tests for a headphone amplifier can be applied to just a universal output without a formal presence of an amplifier, if in this mode you can connect headphones to this output. Based on the results of the tests, you can understand the real picture, is the output powerful enough or not, with the initial data on the circuitry as a "black box".

        More detailed

        Measurements of Creative Sound Blaster X7 LE 4 Ohm Low Gain were carried out by Roman Kuznetsov on the hardware-software complex RAA.

        The Creative Sound Blaster X7 LE 4 Ohm Low Gain test was conducted as a black box test, without regard to cost and prestige. This is the basic principle for making measurements, measurement reports and developing tests in RAA.

        I believe that it is important to do not make an absolute assessment of the device, but an aggregate assessment when working together with a headphones and taking into account external factors. This allows you to effectively reveal the potential of the entire set of devices or to make a more optimal choice of components.
