I have a Yamaha cr820 and a fluance rt85. I've been using new large Advents with them. My problem is occasionally I like to listen loud and the Advents which sound good to me at low volumes aren't cutting it at high volumes. I've been considering whether to buy a higher powered integrated amp as I'm not sure my 55 Watts are driving the advents like they should. This is also my first foray back into high fidelity sound. I am looking at a pair of heresies to replace my current speakers and I'm wondering, with their High sensitivity, if they would play louder and sound better with my Yamaha cr820? Any suggestions for speakers that would match well with my Yamaha or any input on how the Klipsch would sound. Thanks in advance!
