Well, there is good amplification, which is called
sound re-inforcement, because it doesn't change the sound but only helps the audience to hear it, but, sadly, mostly concert amplification does not hit that target.
Chamber concerts give one the opportunity to get up close to the artists and intimate with the music. This is the best way to experience it! I have always believed that Indian classical music should be experienced this way, or, at least in smaller halls seating not more than a hundred or two. I mostly avoid the big halls. Also, the more amplification is needed the worse the quality is likely to be.
Last year, in Chennai, we were lucky to be treated to a twice-a-month series of un-amplified concerts. This was a unique treat. I don't think that amplification destroys micro
tones, but it does destroy micro
details. I recall, at one of the concerts, being amazed at the detail in the sound of the un-miced mridangam: there was a world of sound in an apparently simple
nam that is usually just lost somewhere in the cables.
Flute and nadaswaram are the two instruments that can produce enough volume to fill a fair-sized space without electronics (in fact in-door nadaswarm is a bit much). With vocal, violin, etc, the artists have to work harder, and the audience has to work harder to listen. No bad thing!
Thank you for sharing your joy --- I hope your concert presenters will make it a regular experience for you
