Present system: Denon 3200 85 watt 5.1 (5-6 years old) Vandersteen 1c fronts Vandersteen Center Klipch rear (to be changed out with Vandersteen) New HDTV ( havn't decided on this yet) What I need advice on is whether I should add a amp to the Denon I have or go for a new receiver or possibly seperates: Budget 1000 - 1200 Denon 3805 Pioneer 56txi Marantz 7400 I am looking at an Adcom GFA 7605 or Sunfire Grand Series 5 both used or similar amp to add to the 3200 if I keep it.
