ok i just bought the denon dp-29f for $130 at tweeter. i hooked it up to my denon 3300. i cant get rid of the hum. i moved it around, away from the spekers, on the floor , on top of the big screeen tv. but no luck i still have hum. i also turned of the internal amp that is in the TT. but that produced no sound at all from the receiver. so is the denon 3300 compatible with a turntable even when both are denon? the 3300 has a phono input with a ground attachment on the back next to the rca input. what am i doing wrong? should i just return this and get a different TT? IS THIS receiver able to play a TT without some kind of added amp? help i want to listen to my records that i havent heard in years.
