Advice on Revel Ultimate Studio2 Ex-Demo Purchase

Hi all! I’m hoping to tap into the collective wisdom of the group regarding a purchase I am contemplating. My local Revel dealer is offering his floor sample Studio 2’s. I believe they are roughly 5 years old at this point. I love these speakers and have been lusting after this line for 7 years - and they are marked down to 50% of MSRP. They look to be flawless cosmetically, however in my listening session at the store yesterday, I noticed a small amount of distortion / break up in the tweeter of one of the units. It was very apparent on solo piano recordings, less so on louder rock/pop. I pointed it out and the store owner immediately ordered a replacement tweeter due to arrive next week. So my question is thus - the speakers will come with a five year factory warranty - should I be concerned about the tweeter issue? Any suspicions the replacement tweeter will somehow negatively affect the speaker? Any general concerns given the scenario described? I am very close to pulling the trigger, but would value any guidance.
