Digital room correction

When will there be a simple, affordable 1 box solution where digital room correction can be dropped into any 2 channel system? A number of years ago, I owned a McIntosh MEN220 which was a really cool solution, it worked reasonably well and for the time it was introduced, it checked most of the boxes off. The digital technology inside that piece of gear was state of the art 10 years ago (24/96) but when is there going to be an update or an alternative solution?

I don’t really keep up with this stuff so please forgive me if there has been something introduced. I see a good part of this type of technology now in most decent subwoofers. It would be really cool if you could drop something into a tape loop on a preamp if it exists. Thanks in advance.
