Canor Verto D4S and Virus I4S: super test of the amplifier-DAC combo by Stereo NL:

In its July 2026 issue, the specialist magazine STEREO tests the new combination of integrated amplifier and D/A converter, the Canor Virtus I4S and Verto D4S – with a result that is well worth noting:

“After a convincing run through the measurement lab, with tiny distortion levels and minimal residual noise, we were eager to find out whether the first transistorized duo from Canor would confirm the sonic impressions we had previously gathered from the Slovakian company’s test devices.

There was not much need for further discussion: what these two slimline components had to offer, both individually and as a team, was simply a joy. In particular, the ease with which the duo could switch between the most varied demands – from Martha Argerich’s feather-light, floating piano keystrokes to kick-bass tones from Led Zeppelin to Michael Jackson that hit you squarely in the gut – kept us spellbound by the performance.

Admittedly, compared with more muscular rivals, the I4S occasionally lacked a tiny bit of pressure at the lower end, which one might colloquially describe as a somewhat less fat bass. To make up for this, nothing became blurred; structures in the lower registers remained precisely audible without ever sounding thin. Voices from Lyn Stanley to Joni Mitchell stood vividly and in the right dimensions within the room, while sibilants were free from any hissing effects and full of natural nuances and tonal colours.

Even the aggressively priced Eversolo DAC-Z10 could not pull ahead: sometimes it had a tiny advantage, sometimes the D4S did, without it being possible to crown a winner. It depended more on the music material and personal taste than on a question of quality. However, the Canor clearly has the better tactile quality.”
