performed the measurements of the LSA Discovery Warp 1 with my Audio Precision SYS2722 system. The Warp 1 runs cool—after 3 hours of testing, the chassis was still at room temperature. Because the amplifier has a class-D output stage, I inserted an Audio Precision AUX-0025 passive low-pass filter between the test load and the analyzer. This filter mitigates noise above 80kHz and eliminates noise above 200kHz that would otherwise drive the SYS2722’s input circuitry into slew-rate limiting. Without the filter, 378mV
