Shuguang 845B vs Shuguang 845M

Warren,

To my ears, there is no clear-cut best, but the two tubes have very different flavors. Which to use is highly system dependent.

I use a pair of Cary 805Cs. In those amps, the 845M offers more detail, sounds a little leaner, and has slightly deeper and tighter bass. The 845B has a more full-bodied, warm sound with a little less bass control.

I don't have any experience with the Definitions, but with the Druids, I prefer the 845M. The Druids are already warm sounding, and need the neutral sound of the 845M. I prefer the 845B with Gallo Ref 3s. The Gallos are a somewhat leaner sounding speaker, and benefit from the full-bodied 845B sound.

That's funny, Jeff. I have the Gallo Ref 3s and much prefer the metal plate "C" 845s to my 845Bs because, among other things, the Bs are a touch too warm :-)

I have a pretty live room, so I'll probably stick with (re order) the 845Bs. Thanks guys, you've been a great help.

Warren,

I dont think you can go wrong here. The former owner of my Dared 845 loved his 845B tubes.According to him, they were definitely an improvement over the stock 845.. Hey, hows your Def's sounding?

Best,

..Ken

It's been a little over a year with my Definitions and, believe it or not, they continue to improve. The most fun and enjoyment I have ever had out of a pair of speakers since my Magnaplanar Tympani 1D days. Thanks for asking, Ken.
