+1 jomace Buy the best you can. Your entire multi $k audio investment is funneling through one place.
I have high end Signia hearing aids. They are pretty good & MUCH better than the dull lifeless sound I hear without them. However their frequency range of any hearing aid is about 40-8khz
I was looking for better alternatives for someone with hearing loss and stumbled on the ASI 3DME in-ear monitors on a a website called Grand Piano Passion AN OASIS FOR ADULT PIANO STUDENTS AND MUSICIANS WITH HEARING LOSS.
They are designed for musicians, but maybe a good solution for audiophiles with hearing loss. They are analog, have 20-20KHz (although +/- not published) capability and a 7 band equalizer per channel, and are highly recommended by Grand Piano Passion as an alternative to hearing aids for music.
Haven’t pulled the trigger yet, but looks intriguing. You would still need hearing aids, but could buy lesser ones with an IEM for music.
