I have no experience with your Canary amp, but I am using the EML 300B XLS tubes in my SET 300B amp. To me, they were worth every penney.
You can spend more, but you can't go wrong with the XLS tubes.
There are several members that have, or have used, the Takatsuki, Royal Pricess, and the XLS tubes, and I'm sure their comments will follow.
I went from Chinese Mesh-Plates, which I thought were quite good, until the EML 300B XLS tubes took their place. No comparison.
Best of luck, regards,
Dan
