If there is one thing you could change in your current system. What would it be?

I could say a dedicated room but that’s not gonna happen, so I’ll say an affordable (5K)  improvement in resolution, however that could best be achieved. Perhaps moving from my Hegel H390’s internal DAC to a standalone unit. 

During the spring my allergies get worse and sometimes my ears get wax buildup. A couple times my doctor noticed excessive wax and had the nurse use a device attached to the water faucet to clean my ear channels. Sounds like a jet engine in my ears... but clear and better reception after. 

The sound volume of the cleaning bothered me. That volume, which must be well over 100db cannot be good for you... even if only for a minute. 

Then it dawned on me... that the device was really only an elaborate water jet. So, when showering, I simple put a little soap in my ears, take the shower head and point it into my ears, parallel the the ear canal. Takes a bit of maneuvering... but you can tell when it is going in. The sound volume is low, and clean ears all the time. 

If there is an excessive buildup, you can drop some  DeBrox Ear Wax Remover before the shower, then rinse when in the shower... Walla, clean ears. 

I did it myself when i learned how to do it...

I dont need it for sometime now...( clearing ears from wax)

Hearing is more precious that seeing for me... As it was for Ray Charles giving his money for deaf child...He said to the journalist interrogating him "why not the blind as you are "?

He answered with his Ray Charles voice : " there is nothing there "....
