How far over the limit can I go


I am currently just past the recommended 2000 tube life on my power amp. (Audio Research Ref 110).  It still sounds glorious. Am I playing with fire here?  Or, will I notice some degradation in sound that will prompt the re-tube.  I think it's about $1,000 to retube.  

Thanks guys!!!

I used to have a set of Manley Neoclassic 250s. Turned it on with an old set of tubes one day and BAM! Power tube went down swinging and took out a resistor. Luckily Manley sold these clip on replacements so I was able to get them replaced myself. Always a risk with old tubes.
