An interview with the chief designers & co-owners of Canor Audio, made in Slovak.
An amplifier is a complex matter. It is always about details and finesses that are embodied in the overall design of the amplifier. Certainly, a separate components is a better and more uncompromising solution, but it also brings in higher costs. The CANOR AI 1.10 is a perfect example that great sound can be achieved without making a lot of compromises even with integrated amplifier. The TP101 and other types of amplifiers we made, such as the TP105VR+ and TP134, were classic ultra-linear connections that deliver great sound. However, by having a lower damping factor, it is quite hard to pick the right speakers for them. In order to make a more versatile amplifier, we decided for a fixed bias cathode feedback design. The model TP106VR + with 6550 was designed with consideration to that idea. But there was still something missing. It took us countless tests, listening and measurements after we finally get to the design with automatic bias cathode feedback and in pure A class – the AI 1.10 model. This topology can play superbly with 80-90% of the speakers that are produced, although there are always listeners that will enjoy the sound of, for example, TP134.
8. What are uncommon specifics which you would like to point on at the AI 1.10 Amplifier?
Output transformers are made by using custom coils, which we assemble by a combination of EI permalloy sheets and classic EI sheets in the ratio 30:70. A possibility to connect AI 1.10 as a so-called “integrated monoblock” where two amplifiers are connected via a special C-Link bus, doubling the power and improving the parameters. It is a connection without the need of a preamplifier, where the user selects one AI 1.10 as a Master and the other one as a Slave and controls both amplifiers synchronously by the Master amplifier.
9. What are the tube testing and selection methods for Canor Audio products?
As far as the reliability of the vaacum tubes is concerned, the quality of the tubes produced has significantly decreased over the last 15 years. In order to maintain the reliability of our products, we had to deal with this situation. Since there was no tube measuring system available on the market that would meet our requirements, we decided to design such a very complex and extensive system by ourselves. The available systems did not achieve the accuracy and functionality we required – we wanted to store all the measured tube parameters in the database and have the possibility to select the tubes according to different measurement accuracy filters. Last but not least, we wanted a system that we could rely on in terms of the temporal stability of measured data
We’ve been developing this system for about 6 years and called it Aladdin – this system really allows us to select “Aladdin’s miracle lamps”.
In addition to the measurement, testing and pairing of the tubes, the initial burn-in process is also important for achieving ideal parameters and lifetime. For this purpose, we have developed our own “burn-in” frame. All the tubes we purchased, especially power tubes, have to go through the burning process on this frame for 100-200 hours. This way we stabilize the parameters of the tube and the tubes can be further measured and tested on our “Aladdin” device.
10. As the finale’ What music would you take with you on a deserted island ?
Some wonderfull female vocals for sure, any album from Tracy Chapman
….some powerfull male voice, Give It Up To Love album from Mighty Sam Mcclain
….some acoustic music of course, any album from Nils Lofgren
….and something from pop scene, Off The Wall album from Michael Jackson
….and and, if there is any chance for some party on this island, electronic music: Random Access Memories album from Daft Punk !!!
