While the P75 might be immune to its own noise, chances are the rest of your hifi does not have sufficient high frequency filtering on it if it is more than 5 years old. It's only quite recently that all gear started coming with IEC inlets filtered for HF grunge coming from smps's. Older linear power supplies built into hifi gear tend to be poor at very high frequencies compared to within the audioband.
