The anthem has room correction with ARC. I use it in my anthem MRX-520 and it works well even with just a 2 channel setup. But I can also sympathize with the desire for a McIntosh.
The speakers have a sensitivity of 90 db so are easy to drive. Either amp will work fine. If you really want to crank it up, I'd recommend the anthem 200 wpc at 8ohms, the Mac, 100 wpc 8 ohms. (at 70+, I wouldn't recommend cranking too much; save the hearing you have.)
I'd also note that these are heavy units, 38 and 40 lbs. So make sure you can maneuver them as you say you are disabled. There are some nice class D amps that are very efficient and much lighter. NAD masters, Lyngdorf to name a few. The Lyngdorf TDAI-3400 is 18.1 lbs. NAD M32 is 20.1 lbs. Lyngdorf has Lyngdorf Room Perfect room correction. M32 none, although the coming (August) M33 will have Dirac live room correction.
You don't mention the nature of your disability but getting up to put in CDs can be a pain. Might consider a streaming function. Lyngdorf TDAI-3400 will do airplay so you can stream music files from ripped CDs on a laptop, iPad, or iPhone to the unit. You can also load them up on USB thumb drive and play them via an app. Not sure about the NAD.
Will this also serve to amplify sound for TV and movies? If so, the NAD and Lyngdorf can be had with an optional HDMI module for connecting a blu ray player and cable box, and they pass the video on to the display.
If you want old school with meters like the Mac, you might consider the Yamaha integrated amps, 1100,2100, 3000 etc, or a Luxman. The coming NAD M33 will have digital meters via a display, but that's not the same as the allure of real meters. All of these will be pretty hefty units (except the NAD M33), so there is that to consider.
The Mac at one time was my dream amp as well. But my system came to be basically the system for mostly music, but also occasional movies, so my sources became universal players, Oppo. Hence HDMI inputs became important to me, hence, why I use the Anthem MRX-520 even in just 2 channel mode. I think my dream amp today would be the lyngdorf TDAI-3400 with optional HDMI module.
Good luck with your choices.
