I finally pulled the trigger last night on a pair of Rti12's from the Polk Ebay store. Great price, $599. Even with shipping and tax, still better than other deals. However......still approaching this conservatively. I'm very anxious to compare to my current Rti8 set up, which is sounding pretty good lately. I'm assuming the refurbs will still have a break in period, though, so SQ comparisons will be over time. Any recommendations on settings for the new beasts are welcome. Thanks Sherardp for your response. I have the Rti8's bi-amped through the SC-07 (which I know really isn't doing much) using my own home made 12 ga speaker cables terminated with nanners.
My system is finally nearing completion (for now at leaast, until the next upgrade bug bites). Still planning to upgrade my Monster Power Bar 1100 to an APC H10 or H15 and some accoustic treatments in the room and maybe a few cables. I'll provide new photos in the System Showcase after the 12's arrive. :)
