300b vs 845


I own a nice 300b amp but would like to know what I might gain/loose going to a 845 tube. I know I will get more watts and therefore more volume or dynamics, but that's really all I know. I have only heard one 845 amp, a ASL Lalya, its sound pretty good, but a little grainy.
Your thoughts would be a big help.
Thanks

My ASL 1009-845 drives avalon opus ceramique with great impact and dynamics in 24 x 14 x10 feet room. It was a surprise as speaker is 87 dB into 4 ohms. I would have cancelled my order of ASL hurricane if i knew ahead of time.
they're more different than better-worse. What you got now? what you lookin to improve on?
I have a Viva aurora 845 driving Trios using regular chinese tubes. I have had thoughts I would like to try a 2A3 or 45 amp. I know it is less power,only a couple of watts. With the trios it should be enough though. Does anyone have any comments on the comparisons between these tubes and 845. Also, what about cryoed 845. So far I have heard mixed opinions.
I like the 845B tube best. I have tried standard 845's, 845B's, and 845C's. The 845B is clearly superior to the standard 845's. It has a much richer sound with lots of texture. I found the sound of the 845C's too bright for my tastes. The 845C's have more detail and tighter bass, but the sound is a little thin in my amps. On the other hand, the 845B's midrange is very full and pleasing at the expense of the frequency extremes. It kind of reminds me of the WE 300b sound.
