I now have a different pair as I had to return my original ones because of trouble with the right driver (I suppose). The signal didn’t completely go out but after a couple of days the channels became very unbalanced with very little sound coming from the right. I thought it might be the used SRM-717 I just picked up, but I went back to the store and tested the phones with another amp. Sure enough, it wasn’t the amp and my replacement pair (#1014) works great with it. Not sure what happened, as I certainly did not play the old pair at excessive volumes.
I only needed to work with the store where I bought them because the problem quickly surfaced but I am appreciating that these babies come with a warranty.
Hopefully, this post will be slowly buried over time with my previous pair of SR-009s (#1062) being an isolated case. However, I made this a separate thread just in case.
