I am just shy of you in years and share age related hearing concerns when laying out money on this hobby. I have been lucky, in that with patience, I have been able to repeatedly audition most items of interest to me. In the case of the Mojo two opportunities to audition it went bad so I ended up buying blind and have not regretted it at all. Read all the good comments posted here, discount the bad, and that is what I received hardware wise. Sound wise, every time I upgrade my kit I find more tracks in my collection with flaws in the recording/mastering. Mojo added to my list... You will hear a difference, just not the same as a twenty year old will. As you can easily differentiate between your amps, DACs, and headphones you ought to be good to go Mojo as well. On a bang per dollar measure Mojo scores well. A worthwhile purchase in my opinion. Once I have done my research I have found that further time spent in deliberations would have been better spent enjoying the gear I was considering. Just lost eleven months on a WA22.
