'our hearing deteriorating with age'. LOL. I just discovered this effect in spades! Many years ago I bought a bunch of SED KT88's to power some big mono amps (so I have lots of tubes). I could never adjust to their high frequency response so they sat unused - too lazy to sell even though their value has increased. Well 10 years later I gave them a try. Wow. I can't believe the increase in dynamic's, and a forwardness in the mid range which brings the image further into the room with out the more typical 'brightness'. The only downside is it is hard to ignore the audio effects when you really just want to just listen to the music.
I guess the moral to all this is don't sell anything just re-visit it as you grow older. Now that I have this reconfigured amp I'm going to have to start dragging out some speakers and sources in semi retirement. :-)
