II just had received a used pair of Yorkville YSM1P's that I bought used on Ebay. The units seem to work fine despite the soft domes on the tweeters having been pushed in during transport. I listened to a pair in a store a few weeks ago and the sound quality seems to be the same.
The problem, however, is that after about 20 minutes of operation, this pretty loud white noise starts coming out of both speakers (both seem to start about the same time). Even when you turn the line in signal off, they still emit a fairly audible white noise that does not change in volume despite:
- Changing the trim level control on the monitors
- Unplugging cables (thought it was a cabling issue, but even when unplugged the noise persists)
- Moving monitors away from the wall
I am thinking it must be some sort of feedback that build up in the amps over time, since when you turn them off, and back on again, the white noise is gone - but seems to come back faster once the units have been used for a bit.
Does anyone know what may be causing it, and whether I have been the unwitting recipient of a lemon pair of speakers - important as I have yet to leave feedback on these monitors and am within the sellers 3 day return window.
Not sure if the domes on the tweeters having been pushed in may be contributing to this or if it is something else. Any thoughts, experience or suggestions would be greatly appreciated.
