Here go's, I am building my ht a few pieces at a time. I am having fun researching but could use some help. I am a semi-audiophile-videophile and here's where I am at so far. I bought a pair of Polk Rti8 Floor Standing Speakers. A Polk DSM 2000 micro subwoofer and Oppo BDP83 SE Blue ray. So what receiver should I go with? Onkyo, Harman Karmon, what? The center channel and rear's will be next but the SE has me concerned as to what would be best with it under $600.00.
