I've had a Cayin A50T amp for over 3 years, with on and off periods of listening (I travel a lot for work), and am curious about a few things:
1. Do tubes degrade over time, or simply fail at some point? Essentially, how do I know when to replace them? What are typical intervals for changing tubes? I cannot tell if the quality has degraded a bit, or if I have become accustomed to the sound. I do bias them.
2. Can I make a meaningful improvement to sound quality by upgrading the tubes? Or should I trust that Cayin put the best matching tubes into the amp based on their design?
3. Any good sites for buying replacement tubes?
Huge thanks!
