First, I have been lurking on this site for a while and enjoyed it so finally joined! I have partially finished system with Infinity 4.1t fronts and Il 50 rears. Since I haven't decided on center, I decided to use a "y' connected pair of Polk Lsi 15s from my bedroom system on either side of Panny 50" LCD. I'm using 45tx as pre/pro and after Rabos / MCACC, I was blown away by increase in clarity and presence as compared to other setups I've heard...Anyone else tried this? Thanks in advance for your feedback.
