Thank you all for the information, much of what has been written has been in line with my thinking. The sound coming from my 880’s is terrific, but I would conclude my amp is just adequate. I contacted Axiom to assure me that the Outlaw 5000 would work, and they thought it to be fine. I only used 4 of the five channels so there is a little extra backup power. I sit at about 10 feet from the speakers in a reasonably large bedroom. Occasionally I desire reference levels for orchestral music and I pretty much get there, just worry about pushing the amp too hard which may harm the speakers, however I don’t hear distortion or clipping. The best resolution is to buy a more powerful amp or settle for what I have. Thanks again to all! I really appreciate your input.
