I bought a pair of Klipsch AW-650. I have a Yamaha TSR-7850 7.2-Channel Network receiver. Running speakers wires to the outdoor speakers will a tall order and about 50ft of speaker wire each. Wondering whether the Yamaha MusicCast Wireless Streaming Amplifier - WXA-50 might be a good option here. Power output of 80W at 8 Ohms. Will that be enough power or will it sound underwhelming? Thanks in advance for your help.
