Arcam DV 137 vs. Denon DVD 3910

Hi everyone my pioneer elite vsx 27tx receiver died last week, so rather than repairing it I decided to buy the Arcam AVR 300, it was a NOS unit and the price was great.
So now I am debating replacing my Denon dvd 3910 to the Arcam dv 137. So my question is, will I notice a big difference in video and audio ? or are they pretty well a
close run? I may only get $400.00 for my Denon and the Arcam is close to $2000.00 after taxes are included. I would rather save the $1600.00 if I can.
