I recently purchased a pair of Focal’s 1027Be speakers and was wondering whether I should purchase a power amp for my Yamaha RX-V4600 AV Receiver to get the maximum quality out of them. Per the Yamaha’s manual I’m getting 165W dynamic power to the front main speakers. There’s an Emotiva XPA-2 for sale locally ($300) and I’m wondering whether I should jump on it. <O:p</O:p Any and all input welcome. Thanks in advance.
