Taking delivery of my new SVS sub today and thinking of buying new fronts and center. I keep reading about a Alpha series of Infinity, but by viewing their site I don't see the Alpha....is that a older line? Was thinking of going with the Beta 50s and the cs360 center since the prelude was a bit outta budget. I recently sold my polk fronts, but still have my cs350 center which seems to still be somewhat popular, but can unload with no problem. Would most keep the polk and buy a set of RTi112's or dump the center and pick up the above listed Infinitys? I currently have the old PRELUDE PQPS surronds in the surr rears and the ERS 210 as the sides. One other question.... Do companys like Infinity debut new stuff at CES? Thinking if that is the case I should wait a few days and see if anything new comes out.
