They aren't comparable in price terms so it's a bit skewed. For the same money without a doubt I'd go for the Tag combo; if the A11SR is much cheaper (as well it should be) and your speakers are easy to drive, I'd still consider the denon.
The TAG AV30R is a nice machine but if available go for an AV32. If you read the specs carefully you will notice that the AV30 has significantly higher noise levels than an AV32 (esp in the surround channels). This translates into an audible hiss at low volumes which can be off putting.
I used to own one and it hissed with my M&K speakers. Replaced it and the new unit did it as well ! My Yamaha A2 when used as a processor never produced a hiss with the same speakers and same power amp (a Rotel 1095). Called TAG up and was told that noise levels were as per spec and still industry leading (nowhere near I think) and I should try changing to less sensitive speakers ! I was running M&K's at the time......
However if you can live with the slight hiss go for it - its a very good machine otherwise and nowadays is available pretty cheap second hand etc.
