Measurements of SMSL sAp-9 Balance were carried out by Roman Kuznetsov on the hardware-software complex RAA.
The SMSL sAp-9 Balance 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.
