I guess it would also depend on which generation of 300 se monos one is talking about.
There are four if you look at the Cary manual downloads (original 300se, Sig1,2,and 3).Each one seems to use a different driver configuration.
I use to have the first generation monos (but modified) and it was hypnotic with a life like midrange I have yet to hear equalled. These used a single 6sl7 and I see the follow up Sig 1's use two 6Sn7's so that sound is probably different.
Maybe someone else could give comparisons of the sound between different versions.
