Hammond says the 125ESE has 9.58 henries of inductance. Mike says the RH gapped for 60mA has 30 henries of inductance. I say, 20 henries is the minimum for acceptable hifi bass at a 5K impedance level. More inductance is better.
Given Mike's approach to materials and construction, I would expect better sounding treble as well. I have not, however, actually listened to any of these particular transformers.
