Well; there you go. The man may be onto something afterall. I mean a transformer is an electromagnet. I would like to observe something. Once you take a proven and good functioning circuit add reasonable quality passive components, adjust the circuit's parameters through close attention to scope measurements, the only thing controlling the quality of sound is the transformer. In the dozens of amps I have heard through the years of all types of circuitry, the only significant factor that has seperated them from each other has been the quality of the transformers. In the EAR SE 859, he uses very pricey heavy well regulated trans, Yoshino's hand picked. That is one of the better sounding amps built. So how do we determine which circuit to use since so much is riding on the quality of the iron, the circuit seems almost superfluous. J.R.
