Ii have a set of triton 3 speakers and boston accoustics vr2 center and sourrounds and Denon avr e400 should I upgrade my receiver I have 2models in mine marantz 7008 or Denon avr4520ci or my speakers super center Xl and a set of triton seven any suggestions I need help

Hi - I'd suggest the SuperCenter upgrade, unless you are having some problem with the performance of the receiver. In receivers, we don't have much experience with the Denons, but we do recommend the Marantz (along with Anthem, NAD, Integra and Pioneer Elite) receivers. Triton Sevens for surrounds would be very cool.

My receiver is ok but I believe I can do better
