Have a few questions about the impedance modes on the mainline and will add some full context below:
1. Is the low/high output impedance 32/64 ohms?
2. Is there any practical way to lower the output impedance of the low mode?
I'm using a Denon ah-d9200 (105dB 24-ohm dynamic driver) and I'm happy with the sound, but the impedance is rather low for a dynamic headphone. I'm currently building a Crackatwoa that I'll be using with my high impedance cans. Hoping that there is a way to simply move around some of the transformer connections similar to the power amps to reduce the output impedance on one/both modes of the mainline. The mainline will be fairly dedicated to the Denon cans so I'm ok with optimizing for them at the expense of some flexibility.
