Canor AI 2.10

Canor AI 2.10 – integrated amplifier with valve input stage and Class D output

The AI 2.10 is one of the more interesting amplifier designs at this price point — a hybrid that uses two 6922 valves at the input, feeding Class D output stages powered by a linear supply. The result is 150 watts per channel into 4 ohms, with THD below 0.02% and a signal-to-noise ratio above 95dB. Canor has been building valve electronics in Slovakia since 1995, and the engineering on show here reflects that experience.

Canor AI 2.10 integrated amplifier — CMT board technology and signal path

Every PCB in the AI 2.10 is machined using Canor's proprietary CMT technology — a milling process that reduces dielectric losses to near-air levels. The XLR signal path runs fully balanced from input to output stage, with no level conversion or interruption. Volume control is handled by a relay attenuator rather than a potentiometer, which means consistent channel tracking at every level. These are the kinds of engineering decisions that separate a genuinely considered design from a spec-sheet exercise.

Class D with a linear power supply

The output stages run from a filtered linear supply — not a switching unit — with additional LC filters to suppress the Class D carrier frequency. This approach addresses the main criticism of Class D amplification directly, and the measured performance reflects it. At 150 watts into 4 ohms and 100 watts into 8 ohms, the AI 2.10 will drive virtually anything you put in front of it without strain.

Inputs and system pairing

Four RCA inputs and two balanced XLR inputs cover all the usual sources. The natural partner is the Canor DAC 2.10 — same construction philosophy, same CMT boards, fully balanced connection over XLR. Together they form a coherent system that is hard to fault at the combined price.

Frequently asked questions about the Canor AI 2.10

What does the valve input stage actually contribute?

The two 6922 valves operate at the input, where they shape the character of the signal before it reaches the output stages. The effect is subtle rather than overt — a naturalness and ease that pure solid-state Class D designs rarely achieve at this price.

Is the Canor AI 2.10 suitable for difficult loudspeaker loads?

Yes — 150 watts into 4 ohms with a properly filtered linear supply gives the AI 2.10 genuine headroom and control with impedance-demanding speakers.

What is the best source pairing for the AI 2.10?

The Canor DAC 2.10 is the obvious choice — shared construction standards, CMT boards throughout, and a fully balanced XLR connection that keeps the signal path consistent end to end.
