Well maybe it IS my hearing

I was really bummed when I moved and completely remodeled a large room for audio but it sounded awful. Had acoustic consultant test the room and I couldn’t hear the test signal above 10k hertz. How could I evaluate my system if I couldn’t hear?  Went to doc for tests- bottom line hearing aids to support higher frequencies. Bummed about the need for these and the “microphone” sound I hear.  My HA are high end with latest processors

it took me awhile to adjust my HA to a custom setting for my audio system. But now that I have it, I’m enjoying my music and system again. It’s different with HA, but I’m so happy I did it. My point is that our hearing is where it starts. If there a shortcoming, address it. It will extent your enjoyment and appreciation of your system. Great post Eric

Great thread! I had my hearing checked in 2018 at Costco because I wanted to know more about the process it’s free!
I’m in my late 40s and the Audiologist allowed me to adjust the in-ear “speakers” so they were “at the openings” of my ear canals. A few years ago, an untrained nurse checked my hearing at my yearly physical and placed the “speakers” in my concha bowl—not the openings of my ear canals and told me I was “legally deaf” in my right ear!
The board certified Costco Audiologist laughed at my story and said some unscrupulous Audiologists do the same to sell more Hearing aides.  
The Left/Right beeping tones became fainter and almost unheard. He told me to indicate all sounds, even if I just “thought” I heard something—which is great to know. 
After the first test, he told me he wanted to do another test before he shared my results with me, I was starting to get nervous, and agreed. The Second test was measuring my threshold of hearing and I had to repeat compound words and short phrases back to him. 
I repeated every thing but couldn’t tell, if the last phrase/word was “carport” or “car wash”, the Audiologist told me it was fine and then said in 40+ years of testing, nobody had scored as well as I did—my threshold of hearing was 0dB (weighted) for each ear and I had no perceivable hearing loss up to 8k Hz (as far as he could measure with his equipment)!
I was so happy that I purchased a Benchmark DAC3 HGC and a Modwright Oppo 205 with all the upgrades to celebrate my hearing abilities.
I’ve protected my hearing my whole life and been mocked for wearing double hearing protection while mowing the lawn, attending sports events, concerts, etc. 
I have worked in the audio and hearing protection industry for 25 years and I am amazed at the number of professionals who have not protected their hearing, and/or continue to damage their hearing thru bad habits, or vanity. 
I’d like to post my hearing test results but don’t know how I would do that. 

Erik I'll  be 90 next month and am living, breathing proof of what you say. So, thank you.

I just sent a cartridge off for re-tipping (Denon DL103) and got a new (to me) LP of Gil Evans and Cannonball Adderley yesterday.  Recent purchase was a Marigo Audio Lab "Aida" CD Mat and I'm here to tell you:  It works.  I have hearing aids in both ears (Widex, strongly recommended) and can't hear a thing over 8 kHz.  Probably stretching the truth at that.

It.  Doesn't.  Matter.  I enjoy my system as much as ever. And interestingly enough, I can still discern changes in everything from cables to tubes.  How can this be?  Beats me, but there it is.

I just stay with the crossover settings and interconnects I like music played on.

That should be everyone's goal. :)
