Canor Virtus I4S & Verto D4S: “a real standout in the high-end class”

In March 2026, the editorial team of the online magazine lowbeats.de took an in-depth look at the Virtus I4S integrated amplifier and the Verto D4S D/A converter from Canor’s brand-new Foundation series, and were अत्य enthusiastic—particularly due to their “very refined sound,” “brilliant operating concept,” and “excellent build quality”:

“The two components of the Foundation series can be controlled via the supplied system remote control or directly on the unit itself. We have already introduced the multifunction knob of the Virtus I4S; on the D/A converter, a large touch display is used. Among other things, this allows you to select sources and adjust the eight different digital filters. Of course, we tried all the filters: the differences are audible, but rather small. In the end, we settled (as with many other DACs offering various filters) on ‘Minimal Phase Fast.’ However, the sonic character of the converter is more strongly defined by its powerful componentry and consistently executed design.

We have already tested quite a number of Canor components and have always been impressed. Admittedly, these were almost exclusively tube models and significantly more expensive. Nevertheless, as with the phono stage, clear similarities to those tube “powerhouses” can be identified. This applies in particular to the amplifier, which delivered a wonderfully harmonious yet powerful performance. The presentation of large orchestras via the Dynaudio Heritage Special, for example, was simply enchanting, both in terms of tonal naturalness and three-dimensional imaging.

In the now rather sparsely populated integrated amplifier price range between €2,000 and €3,000, the Canor stands out not only because of its refined appearance but also thanks to a wealth of sonic sophistication. […] In our listening tests, the Canor ultimately prevailed over the competition because it rendered voices with slightly more expression and, on particularly good recordings, expanded the soundstage further while outlining individual instruments more precisely. A truly audiophile integrated amplifier.

Conclusion
Build quality, tactile feel, and, not least, sonic performance: with the new Foundation line, the small manufacturer Canor aims to make a real statement in the upper class around €2,500. The term “small” manufacturer is somewhat misleading, however, because although Canor is not a large brand, it operates one of the largest hi-fi component production facilities in Europe—where even some competitors’ products are made. This also explains the high level of engineering effort and the comparatively affordable price of the new components.
