New Receiver Advice

Hi,

I’m looking at possibly getting a new receiver and wanted to know what everyone would suggest, or should I get amp instead? I’m looking to pay no more then $1500 and my current setup is listed below, and I do plan on adding more speakers in the future. I use my speakers mostly for Movies, and some time for music.

Receiver: Yamaha RX-V667

Front left and right speakers: B&W 683 S2 loudspeaker

Center speaker: B&W HTM61 S2 600 S2

Rear left and right speakers: B&W 606 S2 Anniversary

Sub: Klipsch R-110SW

Thanks
