I am wondering if there is a hybrid headphone(or speaker) amp that uses an SS driver but a tube power output? Now you might be wondering why such an arrangement would make sense? Well from more then a few articles I have read, tubes have the biggest effect at the electromechanical interface; which means with speakers, microphones, guitars and phono cartridges. The biggest contributor is the output transformer and then the power tube. So is one available or would I have to build one?
