I ordered and received this receiver/amp in July 2012. When I first connected my speakers to it all the modes made it sound like my speakers were bad, lots of hiss, crackle and pop. Well my speakers are over 30 years old, so I thought they maybe the cause of the problem. I finally purchased new speakers the middle of September 2012 and connected them to the unit...same exact noise and problem I experienced with my old speakers.I tried to contact the seller (The Nerds) through Amazon (Contact the Seller) but have not received a response from them at all. I recommend that no one purchase anything from this company as they are NOT buyer friendly. I don't want my money back, just a replacement unit or this one fixed.But they have to quit ignoring my request and answer my email to them first.Sherwood RX-4109 105 Watt Stereo Receiver (Black)
