How loud is too loud

Hi. Im new to the world of audiophile and am hoping someone can help with a problem only nine months in to spending £3000  on my set up. I've got an audiolab 8200p power amp, audiolab 8300cd and monitor audio silver 8 speakers. After playing some fairly heavy house music at -10db I noticed a distinct lack in sound quality when I played music at a lower volume and now it sounds as if I've lost a whole frequency level. There is not distortion as such, it's just that music sounds quieter and less definition in the top end. I always run my system in before turning up the volume and never push it too hard for too long. Normal listening level is around -30db.
Any suggestions greatly appreciated.

Great question;

There are cell apps that record DB for you.

I have a audio group & they all play at different levels.

My ears like softer

When reading & listening -60-65 dB
When really listening - 75-80 dB

One buddy -90-94 dB 

most others -80-85db

yes, I’m geeky

you may have damaged the tweeters

Nothing wrong with a bit of geekiness frozentundra! However, what you suggest is a subjective thing about personal listening levels. This is a definite change from one day to the next in loudness at every level, so when the system is running properly everything is fine, when the fault occurs everything sounds about 10db quieter and almost tinny in the top end. 
I was hoping it was something like damaged tweeters, but I have been unable to replicate the fault at the shop I bought it from when I took it back for them to check out. it seems to be something that occurs after playing 'loud' music?

tcapone,

If the loss of sound quality is still there at loud levels, you blew a driver. if not, you are suddenly self aware of your ear's limitations.

Tuning speakers with a smile like curve helps them sound better at low volumes. Loudness controls in older preamps / receivers was also a great benefit.

Best,

Thanks for all your insight. 

I will carry on with some sound tests and see how I get on. The shop I bought it from have said they will come out and listen to it, so hopefully they can confirm. If not then maybe I really have damaged my ear drums in some way.

To be continued......
