For $1000 or less I would suggest Room Correction technology. Basically these are computers in little boxes that look like audio components. All the digital components-in your case that might just be the CD player-connect. They come with a little microphone. You will need either a computer or a mobile device to do the setup. It takes about an hour. You can generate different settings depending on what sounds best to you. It analyzes the individual characteristics of your room and adjust accordingly. It may perhaps help a little with the hearing loss.
The technology is usually bundled into AV Receivers, so if you are looking to replace your integrated for any other reason you can go that route, or it can be purchased as a stand alone. The two competing companies that I have used are Anthem ARC (as part of an Anthem AVR) and Dirac, which I have as a free standing box that cost around $300 a few years ago. The Anthem was a bit easier to set up, but it has been a few years and since software gets updated frequently that may no longer be the case.
