Shortcut or badcut?

I am quite happy with the sound I have, so I will take the given advice and not mess it up with a dumb idea.  The SuperTweeter seems like the way to go, so I will $tart $aving.

Thanks for the info.  Much ....appreciated.

You will lose your sense of sound stage.

OP... What is your definition of "air?" Is it to increase the high frequencies, meaning more high-end extension? Or are you looking for the phenomenon of air around the instruments? This would increase the space surrounding each instrument and improve focus.

If all you want is more high-end detail and extension, then super tweeters are worth trying. For true "air" in the audiophile sense, then it's more complicated.

Sincere thanks for the info and suggestions.
I just wanted more high-end extension. Sometimes I miss the shimmer and sparkle of the higher end.  I'm also one of those weirdos who think the inaudible higher frequencies have an effect on our bodies, and therefore, our listening experience, just like the very lows do. (I was once exposed to 22kHz, through an apparently loud driver, and although I didn't hear a thing, I felt like being exposed to positive ions, like at the seashore. ) 

Thanks for letting us know. You would like a little more extension, shimmer and sparkle.

Easy! When was the last time you cleaned? If its been more than a year you may be surprised how much extension and detail has been slowly gradually obscured by dirty connections. Yes its a regular maintenance thing..... that hardly anyone does.

Anything more than a year and you should be able to hear a nice improvement even from something as simple and free as wiping everything off real good with alcohol and a clean cotton cloth. Disconnect everything and clean every RCA, spade lug, power cord prong, absolutely every metal contact you can get at.

This is what you can do for free. There’s a million cleaners and contact enhancers out there, all the dozen or so I’ve tried are frankly not a whole lot better than alcohol. (Keith Herron recommended plain old alcohol to me.) But if you can afford it, Total Contact from Perfect Path Solutions is in a whole other league and will transform your system every bit as much as a major cartridge or amp upgrade. Maybe more. If you do your panel then for sure a lot more.

So, how long has it been?
