Hello, I was hoping I could get some advice as to which system would be the best for me. 1) I only have about a $1500 - $2000 budget for everything including the receiver. 2) I will likely upgrade in a year or two so I want a good foundation that I can build upon. 3) I will use the system for movies and also music and my music tastes are very bass intensive. 4) Room size will be 12'-14' immediately, but a bit larger in the future. I like the price of the quintet III to be honest, but feel that I will want to upgrade with reference products in the future so I do not want to have to scrap everything and start over. For example, I could buy cinema 8 today, then purchase floorstanding left/right in the future but still keep the rsx4 as surrounds. So I basically want some entry level reference products that can be modified/upgraded in the coming years. Some combo's I was thinking about: 1) Cinema 8 but with rw-10d sub upgrade 2) Cinema 10 stock 3) Quintet III with Synergy 10 sub (cheap for now, get a completely new system in a few yrs) I'm confused with a few things such as the low end frequency of the cinema 8 vs 10 satellites. The rsx5 has a bigger woofer but has the same 92Hz low as the rsx4. So what makes the rsx5 better than the rsx4? If I'm mixing and matching speakers what is the most important? Woofer size? Power handling? Reference vs Synergy line? For instance what is the difference between the RC10 and RCX4 for a center channel? Can you use either? Finally, can you get these setups on sale at audio retailers or does everyone always charge the msrp on these speakers? I've seen some online that are discounted but am worried about the shipping process.... Thanks in advance for any advice Paul
