My Conquest powercord is the same way and I have tried a Monster Powerline400 and a Verrastarr Silver Reference with Furatech connectors and it was still very loose. I would have to say that is my only complaint about my Conquest and I have had it since 8/08. I have heard about people wrapping a bunch of electrical tape around the plug to make it fatter so it fits tighter into the plug but haven't felt comfortable enough to try it.
I got my Pop to get a Dynasty for his house/room, which is pretty open like mine, and his cord is the same also.
I have it with my Energy Veritas 2.3, 2.0 and PSB S50 surrounds and a Pioneer SC07. I twisted the sub 90degrees the other day so it is firing into our couch and a corner, moved some speakers a bit and changed speakers wires. I had to rerun MCACC and I had to turn the Conquest down to 10 o'clock and it set the sw level at -10. The Hulk will still rattle my neighbors awning when I have it turned up to -15 but I feel like a wuus for having it set so low. I have a 5500cu ft great room with a wide open kitchen that is 3000cu ft and a double wide foyer and a double door opening into the den that adds another 3000+ cu ft and it still "hits" no matter where you are.(even in the shower)
Now I need to get some inexpensive bass traps for the corner behind the couch as it is a bit boomy there and for the upper corner as well but I need something that the Wifey will approve and I can paint or it will be a no go.
Anybody have any suggestions? I would greatly appreciate it. I could even do a DIY trap or if there is a foam block I can buy and then cut I could do that as well but it can't be big or ugly.
Thanks for all the great posts and stories. I especially love to read about the "newbies" once they get them set up and hit in the chest for the first time.
