What tubes are in your Cary 805c?

In my experience, swapping either the 845's or 300B's can significantly change the sound. The 6SL7's make less of a change.

I have experimented with Shuguang 845's, 845B's, and 845C's. Additionally, I have tried KR 300B XLS, 842VHD, and new production Western Electric 300B's. I have tried various brands of 6SL7's including RCA 5691, Philips 5691, Tung-Sol, Sylvania, GE, and standard RCA.

After all the experimentation, my favorite combination is:

Shuguang 845B
Western Electic 300B
General Electric 6SL7GE with the wire top getter

Hope that helps,
Jeff

Let us know how you like the KR's and 845M's. I am especially interested in the 845M's as I have considered a pair of those myself. I liked the 845C's, but they sounded just a tad bright and "hi-fi" to me where the 845B's sound slightly more natural. From what I have read, the 845M's may have solved this issue.
