what is the weakest link in my audio chain


Would like to get some advice on the next best upgrade to the following setups. Music playbacks are very important here.

paradigm studio 40 v2 for fronts
paradigm studio center v2
paradigm studio 20 v2 for rears
Hsu VTF3 MKII as sub
Arcam av8
Bryston 9bst
denon dvd-2910
outlaw interconnect
generic digital coax from denon to arcam
HomeDepot extension cord (10AWG) for speaker wires.

an arcam front end would be the icing on the cake, but i suspect your system sounds really good.
It sounds really, really good. But since my exposure to audio gears is very limited. I am hoping that you can use your experience and knowledge to point me to the right direction to perfect my system even more.
Thanks
This is my opinion.

Replace first (top to bottom)

Sub
Speakers
CD/DVD
Cables
amp

I don't know anything about the AV8 so can't comment on it.

Good luck
Probably the speakers but hard to say.

How much more are you thinking about investing in the system for two channel stereo?
