Testé avec deux autres de sa catégorie, c'est celui que j'ai gardé. Très ouvert, très neutre, très dynamique mais pas "numérique". Un grave incroyable vu la taille. Il vaudrait plusieurs fois son prix si c'était une grande marque traditionnelle.

Topping's PA5 II amplifier is a compact and powerful model, adopting a totally balanced structure and an innovative Class D amplifier circuit, enabling it to develop a significant power of 2x100W under 4Ω with a low level of distortion. The excellent parameterisation carried out by the brand's engineers ensures clear, clean and deep sound reproduction, with no background noise. At 5W and 4Ω, THD+N is measured at less than 0.0004%.
The PA5 II also incorporates an effective and comprehensive protection circuit, acting against overvoltage, undervoltage, short-circuit, overcurrent and overheating.
On the input side, there is a choice of single-ended stereo RCA or two 6.35mm TRS jacks for balanced input. Output is via conventional speaker terminals that accept banana plugs. There's also a 12V trigger on the rear of the unit, enabling the PA5 II to be connected to other devices for automatic on/off.
To use the 12V trigger function, it must be activated using the switch on the front of the device.
