EL34 is not good, IMO, idea for audiophill listening, it is more for guitar amps with more sharp sound, that people senses like detail. I had SE EL34 and SE 300B, and 300 B is better variant with more wide scene.
If You use instead SE output transformer PP transf. with one shoulder for 300B sounding and second shoulder for compensating idle current, bass will be max! Saturation, that is main enemy for sounding and bass,... will be zero! Now I have the same construction with EL11 Telefunken and sound is amazing with small PP transformer.
