So, I have Q Acoustics 2020i, Marantz PM5004 amp & MAudio 2496 sound card. The sound card allows for 88.2KHz output.
Some time back I had tried this 88.2 KHz output and had noticed distortion in sound (only in demanding songs like heavy electric guitar & western classical music). Looked to me as if spkrs would get damaged. So I questioned here in the forum and ppl agreed that there should be no distortion on upscaling.
The related thread is here - http://www.hifivision.com/speakers/57629-do-speakers-buzz-when-music-upsampled.html
So I was careful, but a few days back I got the urge and saw that normal bollywood songs played fine. So I set it to 88.2 and off I went. I forgot to switch it back to 44.1 and played classical & rock songs.
Yesterday I noticed that dreaded scratching sound coming from spkrs when volume is changed.
Now, what has happened here? What is your take on the reason for this damage?
Either upsampled music demands higher power and clipping has occurred.
OR as Marantz amp manual says, higher than 44.1 music requires spkrs to be able to handle higher frequency range.
OR maybe spkrs couldn't handle the higher dynamic range.
OR maybe spkrs having paper based drivers (2020i are carbon fibre & ceramic coated paper) were not as sturdy as maybe polypropylene based ones and blew.
Asking the more experienced ones as I will have to buy new ones and I plan to listen to music upscaled to 192khz.
Thanks.
My dear spkrs lasted only a year :-(
