Mapman, I don't see your response in any way heretical. As a matter of fact, your response here as many of your others seems more in the down-to-earth, experience based approach to problem solving. I know I will never again hear music the same as when I was younger and I finally realize that, save for one component, chasing this issue through equipment changes may be fun but not likely to result in significant improvement.
The component that I refer to is the equalizer. To many self considered audiophiles the use of one falls into the category of heresy and is an affront to their sensibilities. As I've said before, though, if one has an unrestricted budget, a purpose built listening room with all well selected components and has perfect hearing, they will still likely be looking for improvements through addition of or changes to equipment; as an example, upgrading equipment is one of the most popular subjects on these forums.
Now that I'm using the equalizer (Behringer DEQ2496), between automatic room balancing and frequency adjustment to compensate for age related hearing loss, I'm able to get back much of what I've lost. If I had discovered the EQ approach years ago I could have saved significant time and money in this quest. I tried, as I said previously, to use the EQ as a sort of loudness control for low volume listening but it hasn't really worked that well so far. That being the case, I still want to try the autoformer approach and will as soon as my checkbook recovers from purchase the new speakers.
