Prefered 300B tubes for Canary Amplifiers


I'm the owner of a Canary 306 300B amplifier. The stock tubes are EH and I'm interested in upgrading to a premium set of 300B tubes. I'm wondering what others have tried and liked and wondered whether the Canarys can accept the XLS designated tubes.

If you are a working person , the Golden Lion 300B is excellrnt
Can you please explain this remark? Do you mean these tubes won't be effective for someone who is retired, or who is a student?
Cost, he is letting you know that these are very reasonably priced for good 300b tubes. Higher end 300bs  can easily cost 800 to 2000.00 dollars per pair. For example I have Japanese Takatsuki (1800.00) bought about 5 years ago and Czech Republic EML XLS (850.00). Of course  vintage Western Electric 300bs can go for much more.

The Golren Lion 300 B  is a Great Tube long lasting and very musical a little warmer I like these better the the Full music great dynamic driver best value 
B class the Sophia princess are made I. Same factory of the full music c 
now worth the cost . The Golden Lion with good vintage  small  tubes 
great value performance combo. Cryoset matched tubes absolutely 
sound better then non cryo tubes  and last longer . It’s your money .
