I am planning to purchase Yamaha RX V377 AVR. I have sony micro hi-fi component (CMT -NEZ5) Sterosystem which is having bookshelf speakers (with 6 ohms loads, both channels driven, from 120-10,000 Hz, rated 18 watts per channel minimum RMS power, with no more than 10% total harmonic distortion from 250 milliwatts to rated output). Can I match these speakers with the Yamaha RX v377. I am a layman in the Music system world. Kindly help me.
