What audio aspect are you knowledgeable in?

I am an equal opportunity music and gear lover. Personally, I do think that I have a critical ear and have been to enough live unamplifed shows and audio gatherings to have had the pleasure to hear the very best and worst that this hobby has to offer. I know intimately what my system can do and I am able to make comparisons with other gear that I have listened to, just to hear and guage where the given systems are better, worse, different etc. There are just too many quality components available that none of us have the possibility or resources to try them all, but we can try to listen to as many as we can. Even live music sounds different from evening to evening.  So many variables. Enjoy the process 🎶

I stick with stuff I've heard and what I've learned from trial and error over the years. I have no special expertise just personal experience.

I advise you to not listen to advice but to music

I can fill a known glass or carafe to various levels by sound (not sight).

Certainly this special ability must have some HiFi application.

With every one thing I learn, I realize there are two more things waiting for me.

And so on, and so on, and so on...
