I tried to precondition the Creek Destiny by running it at one-third its specified power into 8 ohms for one hour with both channels driven. However, it shut itself off after 20 minutes, and the area of the top panel over its internal heatsinks was very hot. Pressing the Standby button brought the amplifier back into operation.
Looking first at the Destiny's preamplifier section, in passive mode the maximum voltage gain, measured at the preamp-out jacks, was 0dB, as expected. Also as expected, the input impedance varied according to the setting of the…
