I am a veteran with some hearing loss on the high side. My lovely wife bought me a turntable with an upgraded needle and system upgrades for the basement sound system. New amplifier is a Yamaha AS501 and speakers are ELAC DBR62 reference to go along with my existing martin logan subwoofer. The elac towers are moving back upstairs. Not the high end system but a decent set for my basement. I am enjoying the sound but feel I am missing out. My music tastes are broad to say the least. I tend to listen to hair metal, van halen, def leppard, journey, ac/dc etc.... But also old delta blues (lightning Hopkins) , modern jazz, classical (goldberg variatioins by Glen Gould), esoteric (Michael Hedges), etc.... So with this simple explanation how can I adjust my system to account for my hearing loss I am sharing the loss from my latest test. In my youth I always had an equalizer in my system. These days they have dissapeared.
