Veiled 'wet blanket' sound from tweeters

You’ve been exposed to hyper-detailed/bright headphones and now, by comparison, the speakers sound different.

OP, just make sure on the jumpers, that can cause all kinds of problems over time.. Just strip back some good copper, and get rid of the factory jumper. Dirt cheap, just to check, listen and see if there is a difference..

Check all your connections, loosen and retighten them. Plug and unplug them a few times to clean the pins, RCAs, XLRs, ICs and speaker cable if you use them, clean is good... fresh clean copper on the bi /wire/amp speaker post... They go bad.... They get dirty..

Cost nothing... LIKE MC said, did you change anything? always a clue, ay? Remember any loud pops, weird thing? anything?

Merry Christmas safe holidays, EVERYONE... Santa is on his way...

I love watching my Pup open presents.. LOL Junior too, the Bunny...

Regards

Merry Christmas!

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.

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.
