Congradulations on your new amp. Great choice.
High quality audio systems can make up for reduced hearing. I think mostly by revealing the whole spectrum of sound in the music. If you miss a bit of the real high frequency, it just isn’t that obvious. Most sound are pretty large spreads across the spectrum and things like snare drums have a very high dynamic impact so, the stand out.
There are lots of great speakers out there, I would look at Sonus Faber and DynAudio for sure. A very classic combo is Sonus Faber, Audio Research and Transparent wires.
I would not worry about fancy speaker cables right now. I would get the best possible speakers you can afford… maybe used… a few years old. This can get you into a category well above the one you would be looking in new.
Then get your speakers… break them in, get to know them really well.. Five hundred hours or more. Which can easily be a year. Then when you are financially recovered start looking for speaker cables. Do the same kind of work you did picking out your speakers. This way you will be able to audition cables and know when you tried the right one.
This method will hel- assure you you are getting the most out of your purchases.
