Just purchased a Yamaha RX-V1300 from my local authorized dealer. I won't go into details but when I unpacked it, it became obvious that the box had been opened before and resealed. It appears to have been done at the factory...the staples, sealing tape is identical. Everything in the box appears new, wrapped. There is not a blemish on anything. Is there a reason the factory would re-open a box? I just want to make certain I bought a new unit and not something that has been refurbished. Any quick thoughts would be appreciated as I want to take this back ASAP if I need to. Thanks!
