Yeah, that is one thing about airplay that sucks. It is an easy mistake to make, especially if one is not aware it can happen. You may have distorted your voice coil/s on one or more of your speakers. If they hit max excursion all at once they can drive themselves hard and warp or even bend a bit. Doubtful, as others have said, you damaged the amp. Your speakers could be cooked unfortunately. Hopefully you discover the problem and it is easily remedied.
Did I damage my new amp
So, as posted elsewhere, I bought new Monitor Audio Gold 300 speakers which I am still waiting to receive. I was impressed by the Arcam SA30 during the audition so I brought one home to pair with the speakers whenever I get them. In the meantime I am using my 20 year old MA Silver S8’s
Being new to streaming it took some playing around before I figured everything out. But one big mistake was not understanding that the volume on my iPhone also effects the amp volume.
Long story short, I managed to crank the volume on the amp to 100% for a few seconds before I understood what was happening, and got it turned down. ( I found the max. volume setting after the fact)
Since then I find my speakers a bit distorted. Now, I don’t know if they sounded like that with the old amp. Am I just over analysing things, paying TOO much attention to details as it’s a new amp and I’m listening too hard for an improvement, or I damaged the speakers or the amp. It sounds fine with jazz but something more in the progressive rock style and it sounds distorted.
I would like to think that if the amp was in danger it would shut itself down before anything would get damaged. And it was really only a few seconds. I probably will not see my new speakers until next week so I can’t compare with anything and this is got me totally depressed thinking it’s the amp.
What do you all think?
