Here is my dilema....I have all active speakers, Mackie Hr824 for R&L, Mackie Hr626 center, and just recently bought four Tapco S5 active speakers for surrounds (made by Mackie) so that I can upgrade to 7.1. My problem is that I dont want to spend the money for a high end reciever if I dont need the large amps they usually have built in. Even my subs have separate amps. What can I use that will have all of the tunabilty as the high end recievers without built in amps? All I really need is clear signal and a complete set of pre outs.
