I have a
Yamaha RX-A1060BL 7.2 Channel Network AV Receiver
2 Polk Audio RTI A7
2 Polk Audio PSW505 Sub woofers
2 Polk Audio - RTiA 6.5" Bookshelf Speakers
and
1 Polk Audio - CSI-A6 Dual 6.5" Center-Channel Speaker.
Can you help me answer these questions please. How can I tell if my receiver is providing enough power for my currents set up? And should I upgrade to RTi-A9, and if I decide to upgrade to A9's is my receiver powerful enough to run my current set up.
Any help will be greatly apprecaited.
Thank you for your time...
