Hello everyone, new to the forums and since my home theater speaker system is comprised of Polk oldies but goodies, this seems like a great place to hang out and get started in the vintage speaker section. I am running LS90's for mains, a CS350 for center, and a pair of M5's for surrounds along with a Definitive Technology Powerfield 12 and a Yamaha SW-150 for subs. My weakest link is only using a Yamaha reciever for power which will be my next move for improvments. Although the Polk's have a little age on them they still sound awesome and have not found a reason to move them out. I will definitley be asking for some advice here when I am ready to do an upgrade and start looking at power amps. Thanks for reading and hope to be a contibuting member here at Club Polk.
