I understand I cannot put 2 Yamaha receivers next to each other on my rack because the 2 remotes will operate both receivers (even different models) messing up my system and there is no solution (even though Amazon has very good deal on RX-V675 that expires at midnight Nov 27). Question if i buy a different brand receiver like onkyo, pioneer, sony etc will the different brand remote mess with my existing Yamaha? am i completely safe if i put them within 12-18" of each other. thank you
