Aren't there measureable loss differences? From what I have read C cores are about 20% more efficient than the equivalent EI core...this should be pretty measureable.
I have an amp with nice output transformers using big double C cores from JJ (the amp, the JJ 322 is a true sleeper in its sound quality). The output iron is GOSS with laminations only about 0.13-0.15 thick. All made in-house by those former Soviet Block guys (same for the caps). Bass is right up there with the best tube amps I have heard (different in quality from SS so no comparison there really). Extension is good, down 1db at 35Khz. Clarity is just higher than what I hear with similar amps that use EI transformers.
