Goldmund Telos 5500 NextGen: Mono power amp. Maximum power (IEC60065): 1000 Wrms on 8 Ohm / 1 % THD. “At Goldmund, we are transparent about the protocol we use to measure our figures. This is important because (1000) Wrms is a relative metric and depends on the load (8 Ohm) and distortion (1 % THD) used to measure it. Had we used a load of 4 Ohm instead, the Wrms value would have been higher although in absolute terms the amp output power remains the same. To compare the output power of 2 amplifiers, make sure both were measured using the same protocol.”
