Veiled 'wet blanket' sound from tweeters

No speaker can approach the level of inner detail of good headphones for several reasons, among them:

1. The diaphragm in headphones is much smaller and lighter and can have properties which are impractical in normal driver diaphragms.

2. The power handling requirements for headphone drivers is many many times less which further contributes to how light the moving mass can be.

3. Headphones are free from room reflections which can degrade clarity.

4. The air path itself can attenuate very high frequencies, and the air path is many times shorter with headphones.  (I'm not sure that this plays a significant role in headphones vs normal stereo, but it does play a role in normal stereo vs live performances at some distance, like halfway back in a concert hall).

5. Circumaural headphones block outside noise and therefore improve the signal-to-noise ratio, which unmasks low-level detail.

"...No speaker can approach the level of inner detail of good headphones..."

It may cost you a lot more money but no headphone can compare to a really good loudspeaker system. A good loudspeaker may cost several thousand dollars to surpass a $400 headphone but they surely do. 

@russ69, I'm not advocating for headphones as being "better" than loudspeakers.  But good headphones can do some things better, and good loudspeakers can do other things better.  In my opinion good loudspeakers do a far better job of allowing the listener to suspend disbelief and get lost in the music. 

What I was trying to do was offer one possible explanation for gmckay1960's observations.

I have a tough time with that one for me, too. Speaker are the ultimate in sound OFF my head.. LOL. Head phones  can be good, but they wear me out, no matter how comfortable... I just like digging the detail out of floor standers, mid field.. med size room.. 16X20X8 or 9 is fine.. I like to be able to hear outside the headhear too. JUST in case something is going haywire..

YUP 5 X the cost for the same small setup, have to be careful, it could be 10 times that in a quick second.. :-)

Have to get the, the "Titian of tinker", "Most for the money" Mahgister  to ring out a system for you, LOW cost HIGH quality.. LOL I love when he chimes in... He was an avid HP guy, too.. Likes his SQ.. no doubt..

Get a DEQX premate or an Anthem STR. They will show you what the problem is and correct it. The speakers won't have quite the detail of headphones but the will sound a lot better. If you want the detail of Headphones in speakers you have to get ESLs.
