Help, my system seem to have slowly gotten " bright"

I have all all of the same stuff for several years and it has always sounded awesome. Lately thought it has gotten where some of the higher frequencys have like a shrill to them. It kinda breaks up at louder volumns but is noticable at lower ones too. I have swapped amps out, preamps too but no change.

Really the only thing left is the player which is a 7 year old sony hapzeis. the only thing i have is a cheap cd player that is like 25 years old to compare. This player has a hard drive with all lossless music on it. It has an onboard DAC too.

Has anyone expierenced anything like this where a source or a dac degraded like this instead of just quitting altogather ?

Try some good recording to see if the result is the same.listen to your friend system to see if your ears will react the same like your system.My friend has a dirty tweeter on his B&W speakers  when the tech clean them ? Problem solve. He went to audiologist twice. Ears ok.

I had a hearing test 1 month ago at a ear nose throat doc. I get one every  work anyway. Some upper frequency loss but its been that way for some time.

My system

source is a sony hap-zeis hd player that was around starting in 2014 or 

so. No longer made, 7 years old.

preamps, parasound jc2 and also a backert rhumba extreme 1.3

amps  parasound a-21 and a jc5.

speakers revel f228be and also have some f208 also.

transparent audio speaker cables.

AQ red river xlr, 2 sets. 

I have never conciderd the tweeters could be cooked. 

They have failed 3 times on the f208's. Dont know why to this day.

One time at a semi moderate volume. I was there when it happened. Didnt hear anything odd and then suddenly they sounded dead. Is it possable the beryllium

tweeters dont just work or not work like the others that blew ? Like maybe they can be damaged and still make sound? 

Anyway i will get some sort of tone testing cd or whatever and try it out.

FWIW my car stereo and my headphones at work dont sound like this.

You're on the right path.  You have to take your time and continue to experiment until you get it figured out.  That's the only way.  Happy listening.

For reference if anyone’s interested i notice this on molly tuttle and golden highways album city of gold. Very good bluegrass album from someone " flying under the Radar " for lack of a better term. Other stuff too but I have been playing that alot lately.

Its the same sound one hears when someone is public speaking too close to the microphone and you hear that shhhh kinda sound.

I did swap the f208’s back in and they don’t have the shrill like the f228be’s do.

 

The tweeter has to be damaged, they used to outclass the f208’s 

 

I really need to sell some stuff but am glad I have it all right now.
