Anybody tube rolled 845's?

I have a pair of Cary CAD-211AE monoblocks, so I need four 845 tubes. I already have tubes supplied by Cary but these are made in China. I am curious to try different tubes but given the cost of 845's and the fact I need four of them this could prove to be a very expensive exercise!

I am curious to try to KR Audio and the Cetron ones. Both of these are quite a bit cheaper than the RCA 845 (which I understand is the best).

Anyone like to share their experience? Also please state what amp you have and what effect the change had on your system.

Thank you for your response, Jaiello. Could you please tell me what the sonic difference was between the stock Chinese valves and the Cetrons?

Thanks for your responses everyone. People who have been using the Shuguang 845B - have you only compared these to the stock Chinese valves on the Cary, or any others?

Nobody tried the KR Audio 845? I've done a search on Audiogon and the only links that come up seem to be about the KR Audio shorting and blowing up the amp ...

Thanks for your responses everyone. Jeffreyds, I have tried tube rolling the 300B's in my system using some borrowed valves and it hasn't made as much of a difference as changing the input tubes or the output tubes. For the time being, changing the 300B's on my amp is on hold because I have found that the output tube makes more of a difference.
