It doesnt affect your warranty as long as youdont screw up.So if you do screw it up, it isn't covered? IMO, Rotel then still hasn't fixed the problem.
1) Are new units shipping yet without the double bass?
2) Can you ship a current unit back to Rotel for them to fix it for free? (Or, can a dealer do it while you wait, and it *is* covered if they screw it up?)
