Any McIntosh C46 users??

Hello! I am considering this preamp to upgrade from my trusty little McIntosh C712. One of the main reasons is for the equalizer because I have been doing in-room response measurements that have brought some room issues to my attention. I have the TAS review of it but they left out one of the equalizer values. They listed 7 when there should be 8 and I see a hole between 70Hz and 300Hz which I suspect is the missing value. Can anyone read it off your preamp? That is the zone that needs correction and I am estimating the preamp's potential effectiveness.

Also any opinions about its sound is appreciated. Comparisons with other preamps are most helpful for me.

Thanks!
Arthur
