Hello All, This is my 1st post so go easy on me please. My neighbor just moved away and sold me his Denon 1803 reciever and an M&K V-76 subwoofer for $700. Did I do Ok? He also gave me a lot of monster cable S-Video wires and AR RCA cables. I also got a 61" RCA for $1000. All the stuff was less than a year old. Do I have a good start for HT?
