I have the DSL40C with the stock Celestion Seventy80 speaker.
IMHO, there is some fizz that users have described. Some of it went away the more I used the amp, and more of it went away the louder I turned up the amp.
Perhaps my ears just needed some getting used to the speaker.
I wish I could try one with the stock speaker to see if there is a major difference.
I have watched videos of the Fender Blues Junior with the upgraded Cannabis Rex speaker vs the Celstion Cereamback, even that amp sounded warmer with the Celestion Creamback.
