We have made measurements (26.8 dB gain) using our test setup which only has 107 dB dynamic range of THD + N measurement capability. This is what we measured (SINAD 107 dB) and only represents the test equipment THD + N as the NCx500s are better. In listening, these amplifiers are as quiet as a dark night in deep space with intense layering, dimension and power. Please PM me if you would like me to send you the plots. I don't want to publish the plots as some may not understand test equipment limitations. This is a pure Hypex build with the Hypex on board buffer amplifiers and SMPS1200A700 power supply.How is SINAD changed with such difference in gain?
