I have very strong opinions about amplifiers, but, I think you should speak to a hi fi specialist with your needs and room set up. Opinions on a pinball forum will blur your views badly. Very subjective topic, like DMD man to EM man.
For me ,
I run a yamaha RX-V500D 5.1 ( totally adequate ) internet ( network capable ) DAB+ ( digital radio ), lots of output and inputs. This is a superb little amp. I didn't get caught up in the wank factor, but in saying this my needs were very basic as I have a smallish room and full blown 7.2 ( or more setup ) is just going to be wasted here.
Please don't start me on speakers and devices
