I have been using a hand-me-down Bose system and just got a new set up. The new set up is the Episode 700 series In-Ceiling LCR's, Center Channel, and Point 6's. The system sounds great! However, you have to turn it up to roughly -5db to hear it. Below that it sounds very soft, so my thought was that a more powerful amp would be the answer.
I currently own a Yamaha RX-V471 which has been great, but I don't know that its quite powerful enough to push the speakers above, mainly the LCR's and Center channel. I am looking at the Marantz SR5008 and that is pretty much the top of the budget. Would there be a considerable performance difference between these 2 receivers to justify the cost of upgrading?
