Anybody tube rolled 845's?

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 ...

I've only compared the 845B's to the original Cary tubes in the 211's. My system gets almost daily use. That means I will probably need to replace tubes every 15 months or so. For me, its a matter of cost/value relationship - for the price, the 845B's are great tubes. Would some NOS RCA's be better? Maybe, but for the price difference, I will be happy with the 845B's.

I'm surprised no one has mentioned the TJ Fullmusic 845's. Beautiful sounding in my Art Audio Carissa Signature. I had the KR's previously, a certain unrelenting and analytical presentation in my setup. I also had issues with reliability as one failed and a replacement was on its way out when I replaced with the Fullmusics, absolutely no reliability issues with these. I have not tried the Shuguangs, however, Joe Fratus at Art Audio stated I would prefer the Fullmusics.

Another vote for 845Bs. I use them in a pair of Cary 805Cs. I've only compared them to the other Chinese 845s (845A and 845C). To me, they are richer, fuller, and more musical than the standard Chinese 845s. Depending on the rest of your system, you might prefer the 845Cs. These are more detailed with deeper, tighter bass, but are also much brighter sounding. If the rest of your system is dark and warm sounding, these might be the way to go.

By the way, you don't state what 300B tubes you are using, but if they aren't Western Electric, I'd make that upgrade first before upgrading the 845s.

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.
