The sound you are describing sounds like you should look seriously into a tube integrated...
PrimaLuna EVO400 integrated is very, very good and describes your needs to a tee. I would consider changing from EL34's to KT150 to give you more power and a slightly tighter and pushier low end. It's at a small cost of air and space (where EL34's excels).
