How did you come to that conclusion?

High quality amps and separate tend to keep channels (and their power supply) separated to avoid interchannel noise and distortion. And they use better shielding and methods to keep RF/EMI noise from effecting the components. So IMO amps are better equipped to combat noise than hybrid/integrated amps
Cabling is kept shorter in integrated amplifiers - talking good integrated amplifiers not the ones most people hear -- You are welcom to come to my place and hear watt 10 watts is capable of doing with modestly sensitive speakers. Some people would like to argue my speakers are only 89,5 db sensitive rather than the the 93db in corner measurement -- so if we take the 89,5db rating that illustrates even more so what 10 watts is capable of doing.
