I've been talking with Emotiva via emails and the phone over the past week about the hum/vibration in my XPA-3 (nothing to do with speakers). They are willing to let me return it for another one when they are back in stock, or let me exhange it for something else now. There're going to pay the shipping as well considering it's not being sent back simply because it's not liked, but because something might be wrong with it.
I mentioned my interest in the XPA-5 to them, they said that they would send me one if i decide that's what i want to do, of course i'd have to pay the difference which is expected, but they will still cover shipping. Also, they will test it out for me before they send it to make sure everything is working correctly. But the amazing thing is, they said that they will send it out and not charge me the difference until after i receive the amp, hook it up, and decide i'm happy with it. The woman i spoke with told me to just try it out for a little while and make sure i'm happy, and then call her back in the beginning of March sometime and let her know if i want to keep it or not. Wow, simply wow! That is just top notch customer service right there, i've never been treated so well by any other company, ever! I'm just truly amazed!
So they shipped the XPA-5 out today and i'm pretty excited for this thing to arrive. I think this all might work out for the best, considering i wanted the XPA-5 to begin with but it wasn't in stock.
Now i wait, ughh, the hardest part...lol :D
