“In general, Class D amplifiers are characterised by an extremely high efficiency of around 90%. They are therefore extremely efficient and therefore generate little waste heat. Large cooling fins are not necessary; the I35, despite its high performance, only needs a few small heat sinks attached directly to the components […] We were particularly impressed by its breathtaking speed. The amplifier organised the complex sound in a lively and tight manner, skillfully distributing its almost endless reserves and achieving maximum dynamics, while the CD player brought the finest details to light. What a successful combination! ” Stereoplay Highlight
