anthem avm20 vs integra dtr 80.1

I would like some input on what I should do on picking between a integra dtr 80.1 that a local dealer has used for $1400. I have a anthem avm20 2.2 that I would be replacing. would I be stepping down going to the integra,I would appreciate any thoughts.
As it is a local dealer, you take it on a trial basis, or perhaps take your unit into the shop and have it connected. Let your hears be the judge and jury. Don't forget to consider ease of use between to two units.
