Hi I'm a newbie, I've been using a Paramount Pictures (not connected to the film studio) 5.1 surround for about 15 yrs. After watching Terminator Genesis at a friends house recently through his onkyo 5.1.2 atmos, I'm looking to update my home cinema! Im not sure on speakers yet, but I've got my eye on the Denon AVR-X2300W for ?399... when out of nowhere another friend offers me an Onkyo TX-NR838 for ?400. I was just after advice on which one to choose, or whether to go for something completely different? Also which speakers to marry them to? Ideally I'd like an atmos package and total spend would be sub ?1000? Any and all suggestions welcome thanks! ?
