I solved this problem by having separate headphone system and main system. Certainly more expensive but incredibly flexible and you can optimize the sound for headphones.
Output from Mola Mola preamp to Headphone Amp?
I have a Mola Mola Makua preamp and will likely acquire a headphone preamp. I’m wondering if I can use the secondary line out of the Makua to feed the headphone preamp, and simply have the Mola Mola’s volume set to 0 when using the headphone pre?
Would this end up frying the headphone preamp when I am listening to my main system and have the volume cranked up?
If not, will this have any negative effect on sound, not being a true line out without the influence of the volume control in the circuit, even if the gain is set to 0?
