I'm looking to upgrade/build my home audio/theater set-up. I already have some built-ins for my front and rear speakers (brand: Jama) left to me by the previous owner of my home. I'd like to stay around $700--while keeping the built-in speakers (since I will likely only be in the home a few years)--but I could creep up a bit if I am duly advised and convinced. I'm thinking of the following: Denon AVR 1802 - Approx. $360 online Sony Sub (SAWM40) Approx $150 online Center Channel - Thinking of going with JBL S-Series. But most of posts on forum suggest to keep same brand as front and rear. I can't tell quality of built ins just yet--I'm presuming their average at best. And I pretty much can't get the brand easily. These seem to be pretty well liked on the forum. How would they all go together?? Are these suitable purchases? Or should I just go with a solid Home Theatre in a Box (e.g Kenwood HTB 504--which has gotten some good reviews for box sets) and upgrade components later. Thanks for all your help. Happy new year to all!
