Like the title says I'm just finishing up my theater and now that it's tax return time I have a little spare cash to replace my 15 year old receiver that I've been temporarily using. I want to purchase a refurbished model from accessories4less.com to get the best bag for my buck. I've been looking between Marantz, Onkyo, and Denon and really don't have a preference. What I do need is at least 7 channels (9 is preferred but not a deal breaker). I don't care about 4K, but it has to be able to do 3D. Also one that hooks up to the network for Spotify would be nice as well. My budget is about $700, lower is better, but I could probably go up a little bit if it'd make a big difference. I'm trying to save a little to upgrade my mains eventually. I'm a noob, help me out!I'm no audiofile, I love my bass HOT and I can't hear over about 9-10K hertz if that matters at all.
