Thank you HiFi Review and especially George Fung for the review. Indeed Class D amplifier like all other amplifier topologies that has good/bad design. In these days one cannot use a simple way to describe an overall sound by looking at what class it is. Although we don’t expect Class D is warm as melting butter like 300B.

Eximus S1 and Stello Ai700 are both very modern sounding amplifier with neutral tonality. I have extreme respect to Stello/Eximus team to combine elements and produce a very gooding device without ultra expansive costs.
