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 ?

Again, I would recommend having your ears checked.  What you describe might be the start of hyperacusis, an ear condition.  

If it is an equipment issue, my bet is on the speakers.  But, it would be extremely unlikely that both speakers have the same degradation, and to the same degree, so listen to each one alone to determine if there are differences between the two.  If they sound the same, the problem is probably elsewhere.

Do you have a tube preamp?  Could the coupling caps be going bad?

Op’s ears became more natural sound mode from un-natural Hi-Fi ear mode. Many people (almost women, non-audiophiles) are always in natural sound mode and they hear un-natural Hi-Fi sounds as bright and noisy.

All Hi-Fi systems sound like a left speaker in below video. Alex/WTA

We can only guess without knowing the whole setup. Could this be an outside issue with your electrical, something introducing a lot of noise in your house or neighborhood?
