I am selling my Harman Kardon AVR-510 Receiver. It is a very high quality 5.1 receiver if that is all that is needed. For Surround Decoding it has: Dolby Digital 5.1, DTS 5.1, Logic 7, and Pro-Logic. For power it has 70wX5 for surround, or 80wX2 for stereo. It also has a preout-main-in loop so it can be used as a stand alone amplifier. Included with the reciever is the AM Antenna, the Main Room Remote, and the 2nd Zone Remote. I do not have a paper manual, but I can include it as a PDF file on a CD-R if requested, or it can be downloaded from HK's website. I recently upgraded to a DA4es that is why I am selling it. The receiver is in good condition with no scratches, and performs like new. If interested the build date of the receiver is March 2001. Asking Price 320 USD Plus shipping from 53132 Would prefer Pay Pal, but can also take a Money Order or Cashier's Check Would also consider a trade for a similar value Digital Camera or an ES SACD Player.
