Hi. Brand new guy here. My soundbar died and I am looking to set up a new entry level budget sound system. I'd never even heard of Wiim until last night. That being said, I'm set on getting a SVS sb1000 pro subwoofer. I also think I'm going to get a couple used Kef Q750s from ebay which are very reasonably priced. I keep seeing that for this type of set up to get the most of the system, you should get an amp in addition to your receiver. 
So there's an old 90's denon AVR 1800 I can get for $100 (it works fine but it doesn't have any hdmi inputs or wifi or bluetooth etc). It's got pre outs for an amp, 7 channels for the speakers and sub, and it's 80watts per channel. I was thinking I could get the Wiim ultra. 1.It would be my amp; 2.it would get me the wifi and bluetooth for spotify; 3.it's got the hdmi input for playstation/blu ray. Will this work? Would I run the wiim into the denon or vice versa? And would I be able to add a center channel in the future or will it only work for stereo speakers and sub?
