The weather in Singapore during this "season" is crazily warm and humid. We are looking at between 31 and 33 degrees Celcius. The good news is that the weather here is predictable most of the time. While the rest of the time, rain duration is unpredictable. It can be as short as 15 minutes, but it can also go on for hours and hours.

When I have some time to myself, I'll retreat back to my room listening to music. I listen to quite a wide range of genres. Lately, I have been indulging with this particular album called "Plays Gershwin", by The Bassface Swing Trio. Recommended by some friends, I find the recording to be highly transparent, dynamic, and detailed. Soon, it will become my go-to reference album.

However lately, I am beginning to hear more "distortions" from a tweeter when a piano is being played in the music. I am curious if it is a recording distortion or a "breaking up" mode of the tweeter. Sometimes, it can get as bad as cutting through the ambience of the music. On the other hand, I've been thinking if I should get a new driver to replace it. Could you guys help enlighten me?

I believe there is a post earlier in the thread about distortion.  I've had it from time to time but not lately.

Might try looking at page 187 and a bit before and a bit after.

James - about your perceived distortion. I'm guessing that a recording that is good enough to consider as a reference does not have the type of distortion you are reporting. If it emanates from one channel, swap channels. If it swaps, it's somewhere upstream. Of course I'm guessing, but it sounds like a loose tweeter voice coil. Do you know Rob at Coherent Service? He can help troubleshoot as well as rebuild the driver.

Thank You for the follow up. We have similar weather this time of year.
I have read about The Bassface Swing Trio. I will check out "Plays Gershwin".
Regarding the Tweeter distortion, if you are experiencing the same aural findings on piano recordings, it could be a loose voice coil. I agree with Tom's thoughts.  Consult Rob Gillum at Coherent Service (CSS) in Lexington Kentucky, U.S.A. for a possible re-build of tweeter.
Keep me posted on this situation.

Happy Listening!
