Rcprince, the whine exists only when both players are conected to the preamp. It doesn't matter if one is turn on or not, I still get the whine. If I connect the DVD only to preamp, no whine. I've even disconnected the ac plug on the DVD and still left the source on preamp selected as DVD (with SACD connected) and still get the whine. I wish I had some cheese to go with the wine. I'm wondering idf ots a ground loop or something wrong with amp/preamp. Will need to contact HiFi Farm next. Thanks,Mike
Help Not 60Hz hum but 10Khz wine noise
I have a high frequency wining noise that increases with the volume. I have 4 dedicated 20 amp plugs, my SACD player only is grounded (Aloia amp/preamp and DVD player ground is lifted), no interconnects are touching. Never had the noise with just the SACD connected but as soon as I added the Tech DVD A10N the noise appears. The noise comes and goes also. But, if I disconnect the SACD ic at the SACD rca jack, the noise disappears (leaving the A10N connected). If I plug the A10 into the same preamp position as the SACD (SACD not connected), no noise either. I can't understand why the noise would come and go. Next step is to connect the A10n to another circuit (original home service) and then separate the dedicated ground (separate ground loop installed outside for 20 amp dedicate lines) the electrician combined with the existing ground to stay in code. Thanks
