Life of KT150 tubes on ARC Amps


I have Audio Research 250SE amps and the tubes in it have 2400 Hours. I wanted to hear experience from other ARC users if they replaced KT150 tubes before 3000 Hours.  I am not sure if i need to replace them now or wait for some more time.   I dont have new set of tubes for me to compare with my current tubes and wanted to hear from other people who replaced the tubes.

For the price of retubing a big amp directly from ARC, one can buy a used Music Reference RM-200 (100w/ch), which needs it's four output tubes (a pair of KT88 or 6550 per channel) replaced only every 10,000 hours. And like folkfreak's VTL, the MR tubes are fused, so no fireworks ;-) .
So you suggest I should of bought 5 Hyundai Santa Fe instead of my Porsche 911?   :-):-):-):-):-):-)
bdp24, what do you do when you are not pimping for Roger? I mean really man, give it a break. It is tiresome. 
Don't think you want to know.

From what I heard, ARC recommended tube hours is based on performance and not tube life.
