Audio Research CD9 tube rolling ?


I am wondering if anyone has experience with changing out the ARC factory tubes with other brands of tubes and if so what were the results?  I have an  ARC REF CD9 that is probably due for a tube change given its age and use. I know a new tube set from ARC is about $500 so I thought maybe some AG folks have done some experimentation.  
Thanks

$500! That's pretty good for $150 worth of tubes!
(That will probably be good for another 5 years, he wanted to say....)
