New Tubes- Need Burn-In?

Hey guys- a question.

I just put a new matched quad of Electro Harmonix KT-88EH in my Cayin A-88T Integrated. I properly biased the amp, and after a couple of hours of warm up there is still a touch of "glare" or hardness evident.

I know these brand new tubes need time to burn in...how long a wait is reasonable before I decide whether the EH tubes are the ticket or not? Any tips on what to expect?

Thanks!

I bought a quad of EH 88's for JOR the other day. What an absolute waste of money, thank god the seller refunded almost all my $100. Not even close to the stock KT90's. The Jadis guy said it would cost me like $800 to get a quad of Jadis 88's.
btw Dan how is the bass in the Cayin A88?

Dan I have plans to get the A88, months off though. What did you pay for the Svet quads? And the 2 sets of pres? Why did you use 2 different types of pres? Different #'s?
I may replace the tubes in my Cayin cdp if that will make a difference.. Any help appreciated.
