Our take on the brand
Look inside the brand
Our interview with the brand
What are two key technological innovations or strong opinions that differ you from other brands?
We consider ourselves specialists in tube technology. This year marks our 30th anniversary at Canor. Over the past three decades, we have amassed a wealth of experience in tubes and the design of tube-based audio products.
In addition to our core offerings, we design and manufacture audio products for other brands as an Original Design Manufacturer (ODM). We also designed the tube testers, which are essential for precise measuring and testing of tubes. These testers allow us to carefully select and match tubes for our products. Additionally, each tube that passed the measuring and testing process was assigned a unique number. This allows us to track the tubes used in our amplifier and provide the exact replacement for the customer when needed.
Furthermore, we have developed tube “burning” (or ageing) stands that are used to age the tubes we source from producers. This process ensures that the tubes' parameters stabilise before we proceed with precise measuring, testing, and pairing.
As a second technological innovation we are proud of is so-called CMT technology which we used in our tube-based products. This technology allows us to approach the dielectric loss factor (loss tangent) of printed circuit boards to the air loss factor. With this technology, we have achieved such excellent parameters as can be achieved with "wire connections" only by using very expensive and high-quality wires with Teflon insulation. However, our new technology has the advantage of repeatability in production with a 100% identical geometric arrangement (which is not possible with "wire-to-wire" connections). In addition, the advantage over "wire to wire" is that the connections are several times shorter than it is possible to achieve with a "wire to wire" connection.
What's your approach to customer support?
We appreciate every customer of Canor, whether they purchased an old amplifier 25 years ago or the latest model. Our strong relationships with partners, distributors, and dealers ensure that customers can reach out to them with any post-sale inquiries.
In addition, we are here to assist customers directly from all over the world. Anyone can contact us with questions about Canor products or any technical issues. We can provide remote support or collaborate with local service centres by offering technical advice or schematics needed to fix any problems that may arise.
We understand that deciding to buy a new audio product is a significant process. We are also available to assist potential customers by answering any questions they may have, including helping them match our products with other audio devices or loudspeakers.
What are your favorite tracks for showcasing the strength of your products?
That's a tough question, but if we must choose just three tracks, I would mention the following:
- Dominique Fils-Aimé – Rise
- Paul Cauthen - Cocaine Country Dancing
- Two Feet - Had Some Drinks
- And bonus: Rage Against The Machine - Fistful Of Steel
What other products pair best with yours?
We really like Fink Team loudspeakers (Borg, Kim) and Epos speakers. When it comes to more commercial (or well-known) brands, Focal is the one we enjoy playing with as well. Our amplifiers are designed to be compatible with most loudspeakers, and we believe our customers have had very good experiences with other brands.
