Ayon CD-2 Tube Changing

To those of you who have the Ayon CD-2, does anyone have expierence changing the tubes. It is not in the manual. Thanks Stephen
Stephen kick back drink some cold suds in the dark tubes and enjoy it ;)
I believe Ayon discourages one from rolling tubes in their CD players. Would check with the distributor or Ayon directly first. May void your warranty.
Do you find the Ayon aggressive and need to tame it down a bit?
