The price comps on this are very strong vs. $780. If you had pieced this system together over the past few months, you would have spent $1,010: $160 (FP on mains) + $300 (FP on subs) + $250 (center) + $300 (surrounds).
The mains are the RTiA3 bookshelves, that hit the FP at $160/pair earlier this year here: https://slickdeals.net/f/10130712
The lowest I have seen the center (CSi-A6) was $250 back in September here: https://slickdeals.net/f/10576216
The FXi-A6 were $300/pair during the same sale.
Finally, the cheapest (non GC) offer I've seen on the PSW125 is $150 each here: https://slickdeals.net/f/10946279
