The Marantz pre 7 clone like M7i are supposed to be very close to a very good piece of kit, could the outputs intended for monoblocks not be easily redirected to a headphone output?
Has this been done?
What upgrades might be conducted on the kit?

from memory the output impedance is kind of high so not at all a good match though i could be wrong.I get a chance will look at the schema and give a better answer ;D

original manual for the "7" www.hifilit.com/hifilit/Marantz/marantz.htmschema www.hifilit.com/hifilit/Marantz/model7man-6.jpgthe 12AX7 is not the best tube for driving interconnects not to mention headphones even though the final stage is a Cathode follower.Likely you would not want that output to see anything less than 50K-100K without help-turning it into a "Mu Stage" going to active buffering. Hang a zero gain straight buffer on the output and yes,you will have a headphone amp
