best reciever on a budget for my polk speakers
I have 4 ts15 bookshelf speakers, 2 ts50 towers a psw108 and a psw505. I am looking for an affordable receiver to make this sound good. I am currently using a yamaha 202 but its only 2 channels so I am not sure I am getting the best I can out of my setup. possibly could use a wiring setup. please help.
