I wonder if you are referring to the XPA-2 amplifier. I had originally looked at that, but, at around 70 lbs., the weight was simply too much for the cabinet shelf on which it would need to be placed!
While I continue to be happy with the UPA-2 as it's breaking in, I did find it unnerving that there was smell that lasted for a little better than 5 hours. Tech Support quickly responded to my inquiry by telling me that there can be a smell at the beginning, but that it should fade -which is what has happened.
I've never heard the Gallo speakers, but I would be very interested to what you think of them when matched with the Emotiva.
