Best 300B SET

Hi Pani,
I find the good 300b SET amps allow me to enjoy any genre of music. I'm primarily into jazz, big band and some classical music. However when I do play electronic Chicago blues or rock at home it is very satisfying and gets me very involved. I've concluded that it's really all about the amplifier and speaker match. My amp and speakers are made by the same builder so that's certainly an advantage(and short cut) for me. I share your thoughts on the fabulous midrange they provide. Personally the most nuanced, realistic tone and timbre I've ever experienced so far.
Charles,

Pani, I happen to very much enjoy Rock and pop and heavy rock music on my 300b amp and speakers. The guitars drums vocals, etc simply jump out and grab me and take me on a wild room filling textured ride.

Rock with 300b's in the right system is deff a go!

Jet, absolutely +1, same results!

Pani- I'm sorta in your camp. 845 works better for more that kind of music.

Discussions like this sometimes ignore the individuality of products. Which 845 or 300b amp? There's is a hierarchy and some will be better than others no doubt. What speaker is being driven? Another huge variable to factor in. It's difficult to group all together and genaralize.
