Not much, but it's mine
RB-81 II Bookshelves
KSB 1.1 surrounds
KSC C1 Center
Marantz NR1604 receiver
2 Martin Logan Dynamo 700's
Recently snagged the 700's for $145.
I'm under $900 in for the entire set up.
Future upgrades are larger TV, and matching center/surrounds. The marantz is the first receiver I have owned with Audyssey and the tweaking options are overwhelming to be honest. I will say that I did not like how it sounded once it was all calibrated. Sounds better manually setting it up.
Subwoofers aren't in optimal spots, but my living room is basically a shoebox and placement upfront was the only option.
