I have read a lot of information on what gauge of wire to use, I'm just on the fence with what's the best to use, they say the power rating is 150-600 peak, not going any longer than 15 ft for my floor standing r28f's. 8 ohm compatible? I like to listen to it loud, got A Yamaha 683 amp. Everything I've read is leaning towards 16 gauge, but will 14 gauge impede or will it sound better? Going to run 16 gauge for my bookshelf and ceiling speakers. Only 25 ft runs each. Just figured with the big floor standing speakers I would need a thicker gauge. Thanks in advance
